U.S. Army’s Modular Redesign: Issues for Congress

Summary
In what the Army describes as the “most significant Army restructuring in the past 50 years,” it is
redesigning its current active duty division force to a 48 brigade combat team (BCT) force. The
Army National Guard and Army Reserves will also redesign their forces in a similar fashion. The
planned addition of active duty brigades and the conversion of Army National Guard brigades
could provide a larger force pool of deployable combat units to ease the burden on units presently
deployed, and possibly to shorten the length of time that units are deployed on operations. The
Army has three other concurrent initiatives underway that it considers inextricably linked to its
brigade-centric redesign: rebalancing to create new “high demand” units; stabilizing the force to
foster unit cohesion and enhance predictability for soldiers and their families; and cyclical
readiness to better manage resources and to ensure a ready force for operations. These initiatives
involve substantial cultural, policy, organizational, and personnel changes.
Some experts believe that modular redesign, selective rebalancing, stabilizing, and cyclical
readiness are prudent actions that should provide the Army with additional deployable units and
also eventually bring stability to soldiers and their families. As long as no additional significant
long term troop commitments arise, many feel that these initiatives could help ease the stress on
both the active and reserve forces. As the Army continues its modular conversion, it may have to
contend with budget, personnel, and equipment shortages which could impede plans to build this
new force as intended. Some also question if the Army can afford both its Future Combat System
(FCS) program and its modularity program. The 110th Congress might decide to examine these
and other concerns in greater detail. This report will be updated.

U.S. Army’s Modular Redesign: Issues for Congress

Issues For Congress
The United States Army is involved in a total organizational redesign of its combat and support
units to better meet current and future operational requirements. This redesign effort, as well as
associated rebalancing, stabilization, and cyclical readiness initiatives are deemed important by
proponents as they are intended to sustain both the active and reserve Army through a potentially
long term, manpower and resource intensive war on terror.
The overall issue facing Congress is how well the Army’s modularity program is progressing and
what are some of the issues affecting this major redesign effort. Also of critical importance is the
Army’s ability to fund both the Future Combat System (FCS) program and its modularity
program concurrently. Key potential oversight questions for the 110th Congress can be
summarized as follows:
•

How will the Administration’s proposed increase of 65 thousand soldiers impact
the modularity program?

•

Are some Brigade Combat Teams vulnerable to enemy armor?

•

Is the Army’s overly-optimistic in its ability to fully fund modularity and the
Future Combat System (FCS)?

•

How are the Army’s rebalancing, stabilization, and cyclical readiness efforts
progressing and what are their associated costs?

•

How does the Army’s Force Generation Model impact the manning and
equipping of Army modular forces?

The 110th Congress’s decisions on these and other related issues could have significant
implications for U.S. national security, Army funding requirements, and future congressional
oversight activities. This report addresses the U.S. Army’s redesign of its current force structure,
based on large divisions, into one based on smaller brigade-level modular brigade combat teams
(BCTs).1

Background
What the Army Intends to Achieve by Modularization
The Army maintains that by organizing around BCTs and Support Brigades, it will be able to
“better meet the challenges of the 21st century security environment and, specifically, jointly fight
and win the Global War on Terrorism (GWOT).”2 Accordingly, the Army hopes that
modularization will result in:
1

According to Department of the Army Pamphlet 10-1, “Organization of the United States Army,” dated June 14,
1994, a division consists of approximately 10,000 to 18,000 soldiers and a brigade consists of approximately 3,000 to
5,000 soldiers.

Army positions and also for programmatic accuracy purposes.

U.S. Army’s Modular Redesign: Issues for Congress

Support Unit Modularization
Multi-Functional Support Brigades
In 2005, the Army defined the roles, designs and numbers of support brigades to be developed.
The modular support brigades consist of both single function and multi-functional designs. The
Army’s Multi-Functional Support Brigades include6
•

Combat Aviation Brigade (CAB): Consisting of between 2,600 to 2,700
personnel and a variety of Army aviation assets;

•

Fires Brigade: Consisting of between 1,200 and 1,300 personnel, the Fires
Brigade is to have a mix of cannon, rocket, and missile artillery systems and is to
be able to employ Joint fires (Navy, Marine Corps, and Air Force) as well;

•

Combat Support Brigade (Maneuver Enhancement) (CSB (ME)): Consisting of
435 personnel, the CSB (ME) is to have engineer, military police, nuclear,
biological, and chemical (NBC) defense, and air defense units assigned to it. In
addition, the brigade could also have explosive ordnance disposal and civil
affairs units assigned to it;

•

Battlefield Surveillance Brigade: Consisting of 997 personnel, the Battlefield
Surveillance Brigade is to consist of an intelligence battalion, support troops, and
a long-range surveillance detachment. In addition, the brigade can be augmented
with special forces units as well as additional unmanned aerial vehicles; and

•

Sustainment Brigade: Consisting of 487 personnel, the Sustainment Brigade is to
have medical, finance, human resources, ammunition, transportation,
maintenance, and supply and service units.

The Army currently plans to field the following numbers of Active, National Guard, and Reserve
Multi-Functional Support Brigades as indicated in Table 2.

Current Issues
“Lessons Learned” About Modular Forces in Combat8
The Army has compiled a number of “lessons learned” about modular units in combat.
Commanders maintain that modular BCTs are better in interacting with other service’s tactical
elements and that the permanent task organization of critical core components has eliminated
“multiple bosses” thereby simplifying command and control. Modular BCTs have also exhibited
a “significant increase in situational awareness for brigade commanders based on increased battle
command systems.” Commanders also provided favorable comments on the enhanced BCT staffs
and organic combat support and service support elements within modular BCTs.
Commanders also identified areas in need of improvement. Additional earthmoving capability
was identified as a need as was more capability in the BCT’s armed reconnaissance squadron to
“fight for information.” Commanders also maintain that additional intelligence analysis capability
is needed in the BCTs and that BCTs lack organic engineer assault breaching and gap crossing
capability. Of critical concern to commanders was the need for greater bandwidth capacity to
support battle command systems.
The Army plans to continue to evaluate lessons learned from combat experiences and to make
changes to personnel, equipment, and force structure when appropriate. The Army has initiated

changes for both the BCTs and modular support units in terms of force protection, navigational
capability, physical site protection, as well as convoy security and improvised explosive device
(IED) protection based on these “lessons learned” as well as independent analysis by other Army
organizations.

Modular Brigade Combat Team Firepower9
An Army study, conducted by the Army Training and Doctrine Command (TRADOC), reportedly
concludes that modular infantry BCTs (IBCTs) and Stryker BCTs (SBCTs)—which constitute
over 60% of the Army’s combat brigades—lack tactical lethality during the early deployment
phase of expeditionary operations. The Army Study—“Close-Combat Lethality Line-of-Sight
Capabilities-Based Assessment”—supposedly maintains that IBCTs and SBCTs as currently
organized and equipped are unable to:
•

Achieve desired effects against main battle tanks equipped with active protection
systems;

•

Achieve desired effects against main battle tanks with or without explosive
reactive armor at extended ranges out to 6,600 meters;

•

Identify vehicle targets up to 5,500 meters from the shooting platform; and

•

Achieve desired effects against other armored vehicles with active protection
systems.

Proposed solutions to these deficiencies include modifying tactics such as employing volley fires
to overwhelm active protection systems and developing better equipment to increase the lethality
of IBCTs and SBCTs.

Modular Conversions in FY200610
According to the Army, by the end of FY2006 they had converted 31 active BCTs and during the
year, another four active BCTs began modular conversion. The Army National Guard (ARNG)
continued the modular conversion of seven BCTs begun in FY2005 and started the conversion of
nine additional BCTs in FY2006 for a total of 16 BCTs converting. During FY2006, a total of 45
multi-functional support brigades and 86 functional support brigades were converting in the
active and reserve components.

The Modular Army FY2007 and Beyond
Modularization Plans FY200711
During FY2007, the active Army will have 35 BCTs and another three BCTs converting. On
January 19, 2007, DOD announced that the modularization of two BCTs would be accelerated,
bring the number of BCTs undergoing modular conversion in FY2007 to five. 12 These two
accelerated BCTs are expected to be ready to deploy to Iraq in FY2008 if required. 13 In FY2007,
the ARNG will begin the modular conversion of nine more BCTs and by the end of FY2007, an
additional 13 multi-functional support brigades will be converted. During FY2007, the functional
support brigades will increase by four in the active component and 6 in the ARNG.

FY2008 - FY2013
From FY2008-FY2013, the Army plans to convert the following units to the modular design:

FY2007 Budget
The President’s FY2007 Budget Request included $6.6 billion for modularity in FY2007 and an
additional $34 billion between FY2008 and FY200115 but modularity costs are spread among a
wide variety of Army programs, which makes it difficult for many to characterize an exact figure
for Army modularity.

U.S. Army’s Modular Redesign: Issues for Congress

FY2007 National Defense Authorization Act (P.L. 109-364)
The FY2007 National Defense Authorization Act (P.L. 109-364) added $548.9 million for Army
modularity, and directed it to be spent on M-1 Abrams, M-2 and M-3 Bradley, and M-113
armored personnel carrier refurbishment.16 In addition, the Army was directed to develop a multiyear procurement strategy for the Abrams tank and the Bradley fighting vehicle and to also
provide Congress with the full costs of Army modularity.

Modularity Cost Estimates17
Army cost estimates have increased significantly since January 2004 when the Army initially
estimated that it would cost $20 billion from FY2004-FY2011 to increase the number of active
Army brigade combat teams from 33 to 48. According to GAO in July 2004, the Army added $ 8
billion to reorganize the reserve component—bringing the estimated cost for the entire force to
$28 billion.
In March 2005, the Army revised their figures and estimated that modularity would cost at total
of $ 48 billion from FY2005-FY2011—a 71% increase over the earlier $28 billion estimate. In
April 2006, the Army once again revised its modularity cost estimate to $52.5 billion - $ 41
billion for equipment, $5.8 billion for military construction and facilities, and $5.7 billion for
sustainment and training.18 This most recent total does not reflect requirements for creating
modular forces for the Army’s recently announced 65 thousand soldier endstrength increase.

Modularity Versus the Future Combat System (FCS)19
There has been long-standing concern that the Army will be unable to afford modularity and the
Future Combat System (FCS)—the Army’s $230 billion modernization program. Also competing
for Army resources are equipment reset20 and the costs of the wars in Iraq and Afghanistan.
Program cost growth in both the modularity and FCS programs has also contributed to skepticism
that the Army will be able to afford both programs, given current and projected budgetary
pressures.
The Army contends that modularity, FCS, and equipment reset are affordable. While the Army
has made a variety of program adjustments to continue funding modularity and FCS, the Army’s
main argument is based on the Army receiving a larger share of programmed defense resources,
noting that during World War II, defense spending was 38% of Gross Domestic Product (GDP)
but in FY2007, defense spending was only 3.9% of GDP.21 While it is likely the Army will

receive additional resources for modularity, FCS, and equipment reset, there do not appear to be
any advocates to increase military spending as a greater percentage of GDP. This apparent lack of
support calls into question the Army’s underlying argument on the concurrent affordability of
modularity and FCS.

Non-Budgetary Issues Affecting Modularization
Selected Personnel Issues22
Prior to DOD’s January 2007 announcement that it would increase the size of the active Army by
65 thousand soldiers,23 there were concerns that it would be difficult to fully man modular forces.
The Army’s decision to convert to a modular force structure significantly changed the
requirement for Army officers. The Army’s previous plan to convert to 42 modular BCTs
increased the Army’s requirement for officers by 4,131. Approximately 88% of this increase—
3,635—represent requirements for captains and majors. This requirement for captains and majors
has resulted in a projected shortage of 2,708 in FY2007 and an additional shortage of 3,716 in
FY2008 in these grades. The recent announcement that the Army would now create 48 BCTs and
additional modular support brigades will undoubtedly exacerbate these projected shortages in the
grades of captain and major and might also create additional shortages in both officer and enlisted
grades. These potential shortages might significantly affect the ability of the Army to adequately
man not only BCTs but also modular support units. If this is the case, the Army might be hardpressed to create the additional 6 BCTs that it needs to relieve the stress on the Army.

Equipment Issues
As previously stated, the Army is also faced with equipment shortages as it implements its
modularity program. According to GAO, modular brigade combat teams will “require significant
increases in the levels of equipment, particularly command, control, and communications
equipment; wheeled vehicles; and artillery and mortars.”24 Command, control, and
communications equipment are of particular concern as they constitute what the Army considers
the key enablers for the modular brigade combat teams. For example, by 2007, the Army expects
to have only 62% of the heavy trucks that it needs for modular units and less than half of the
Force XXI Battle Command Brigade and Below (FBCB2) command and control systems that it
requires.25 These shortages will likely be even more pronounced in the Army National Guard that
could start their modular conversions with less and much older equipment than most active Army
units.26

Flagging Designations from The Association of the U.S. Army (AUSA) Report, “Active Component Division
and Brigade Combat Team Stationing and Flagging Designations,” August 2005.

This stationing plan does not, however, reflect the proposed addition of 65,000 additional soldiers
over the next five years. The Army has not yet announced the designation of the new units or
where they might be stationed but given DOD’s Global Basing Strategy and 2005 Base
Realignment and Closure (BRAC) decisions, it is possible that there might be difficulties in
finding adequate facilities, both at home and overseas, to station these additional units.

U.S. Army’s Modular Redesign: Issues for Congress

Rebalancing and Stabilizing the Force and Cyclical
Readiness
Other Critical Army Initiatives
The Army has three other concurrent initiatives underway which have been described as “critical
enablers” in the Army’s brigade-centric reconfiguration: rebalancing and stabilizing the force and
cyclic unit readiness. These initiatives involve substantial policy, organizational, and personnel
changes and some observers contend that these initiatives may be more be difficult to achieve
than the creation of modular BCTs and support brigades as they require significant cultural
changes for the entire Army.

Rebalancing the Force
In what the Army describes as its “most significant restructuring in 50 years,” the Army is
presently converting a number of units deemed less relevant to current requirements into units
more appropriate to the types of operations ongoing in Iraq and Afghanistan. This change
involves over 100,000 active and reserve personnel and involves decreasing certain types of units
while increasing others as described in Table 5, below.

The Army maintains that rebalancing will increase its capabilities sufficiently to relieve the stress
on high demand/low density units. This rebalancing is also intended to place more combat
support and combat service support units back into the active component from the Reserves to
improve overall deployability and sustainability, as well as to reduce requirements for immediate
mobilization of reserve units.28

U.S. Army’s Modular Redesign: Issues for Congress

Stabilizing the Force
This initiative transitions the Army from an individual replacement manning system to a unitfocused system. This stabilization initiative is applicable only to Active Component forces. The
objective is to keep soldiers in units longer in order to reduce historically high turnover rates of
soldiers and their leaders and to foster unit cohesion and operational effectiveness. 29 In addition,
this initiative is intended to provide stability to Army families, and could ultimately save the
Army money as it could result in fewer moves for soldiers and their families.

Cyclical Readiness—Army Force Generation30
In FY2006 the Army implemented a new readiness system—modeled on the cyclical readiness
systems of the other Services—to replace its old “Tiered Readiness System” which, according to
the Army, created a “Haves” and “Haves Not” culture - with most of the “Haves Not” consisting
of Army National Guard and Reserve units. Under this readiness system, called the Army Force
Generation Model, units will move through a structured progression of unit readiness over time
intended to produce predictable periods of availability of trained, ready, and equipped units
available for deployment. Under this model, units will fall into one of three pools: the
reset/retrain pool; the ready pool; and the available pool. In the reset/retrain pool units will not be
ready or available for major combat operations but could conduct homeland security and disaster
relief operations. Units in the ready pool are conducting training and receiving additional
personnel and equipment to bring them up to full strength and units in this pool can be deployed
to meet “surge requirements” if need be. After passing the ready pool, units are assigned to the
available pool for one year where they become eligible to deploy for combat and other operations.
The Army hopes to maintain 20 BCTs (14 Active and 6 Reserve) in the available pool on a
continuous basis.
The Army maintains that the Army Force Generation Model for readiness will result in:
•

A steady-state supply of 20 ready, fully-resourced, BCTs and supporting units;

•

Stabilized personnel to join, train, deploy, and fight together in the same unit;

•

Assured and predictable access to National Guard and Reserve units for
operational requirements;

•

Better ability to allocate constrained resources (particularly equipment) based on
unit deployment schedules;

•

More predictable unit deployments for soldiers, their families, and employers;
and

•

Opportunity to synchronize unit readiness with a wide variety of Institutional
Army requirements such as professional schooling needed for promotion and
military specialty-specific training.

U.S. Army’s Modular Redesign: Issues for Congress

Potential Oversight Issues for Congress
How Will the Increase in the Size of Army Impact Modularity?
Congress may decide to examine how the proposed 65,000 soldier increase will impact the
Army’s modularity program. While there are few details available, DOD officials have proposed
creating six additional active component BCTs (about 21,000 soldiers) which would leave 44,000
soldiers to be used for other purposes. Given personnel shortages in the existing BCTs and
modular support units, it is reasonable to assume that an unspecified number of the remaining
44,000 soldiers will be used to fill these shortages. This scenario could result in the inability to
create other types of units—either functional or multi-functional—that are needed to support the
addition of six additional BCTs.
Another consideration is the equipment issue. Reports suggest that current modular forces are
significantly short of equipment in a wide variety categories. These shortages, combined with
equipment loses from operations in Iraq and Afghanistan, have compelled the Army to adopt the
Army Force Generation Model, where units are only fully equipped when they deploy on
operations. These circumstances call into question the Army’s ability to even marginally equip
new units. For example, a new heavy brigade combat team would require the procurement of 177
armored vehicles and 870 wheeled vehicles of all classes. If new Army units are less than
optimally equipped, there is a potential for a significant increase in wear and tear on the Army’s
existing equipment, as more units use a disproportionally smaller amount of equipment. With this
increase in equipment wear and tear will likely come an increased requirement for funds for reset
and equipment replacement.
An expansion of 65,000 soldiers might also have an impact on current and future basing plans.
New units will likely require additional training areas, barracks, and motor pools as well as
family housing. Even if funds are available today to accommodate these needs, the “real estate”—
at home or overseas—may not be available and the requisite physical facilities may take many
years to construct, thereby precluding the Army’s ability to station these forces where intended.

Infantry and Stryker BCT Vulnerabilities
Infantry units historically have been vulnerable to enemy armored forces and, even when
equipped with anti-tank systems, are considered to be at a disadvantage when attacking enemy
armored units. These vulnerabilities, however, could be exacerbated when enemy armored forces
are equipped with explosive reactive armor and active protection systems. Because Infantry and
Stryker BCTs constitute “early entry forces” they might conceivably come up against these
“enhanced” enemy armored forces (before the Heavy BCTs can be deployed) and find themselves
at a distinct tactical disadvantage. Congress might decide to examine this issue of Infantry and
Stryker BCT firepower vulnerabilities with the Army in greater detail. Such an examination could
address potential organizational or weapons systems changes to provide enhanced lethality or
changes to employment doctrine that might mitigate these BCT’s vulnerabilities.

U.S. Army’s Modular Redesign: Issues for Congress

The Army’s Funding Assumptions
The Army contends that it can afford both modularity and the FCS program but this affordability
appears to be predicated on an increased Army budget more in line with historical precedents.
While it is not unreasonable to assume that the Army may receive a greater share of the defense
budget as it attempts to reorganize the Army and at the same time modernize, some consider it
highly unlikely that the defense budget will increase relative to GDP to World War II levels as the
Army suggests. Congress may wish to address the Army’s apparent assumption to insure that the
Army is not basing the funding of its modularity and FCS programs on what many believe are
unrealistic expectations.

Rebalancing and Stabilizing the Force
Congress might act to review, in greater detail, the Army’s rebalancing and stabilization
initiatives. The Army has characterized these initiatives as “critical” to the modular
transformation of the Army, but little is publically known as to how well they are progressing in
terms of new units that have been created or how stabilization is affecting unit cohesion or family
life for soldiers. Given that these two initiatives involve significant structural and cultural change
for the Army, they also likely have significant budgetary implications that some feel are not
adequately discussed as part of Army modularity.

Cyclical Readiness
Congress may decide to examine the Army’s Force Generation Model of cyclical readiness in
greater detail. This new model - a departure from the long-standing tiered readiness system - will
supposedly provide the Army with a trained and ready force pool of 20 active and reserve BCTs
at all times. Such a change will likely have a significant impact on how the active and reserve
Army staffs, equips, and trains its units and will almost certainly have budgetary and resource
implications that Congress might decide to review. Some argue that while it is beneficial to
reduce readiness standards in wartime, others maintain that it permits the Army to under resource
units in terms of personnel and equipment while advertising a “48 brigade combat team Army”
that, in reality, it does not have in terms of soldiers and equipment.
