Army Logistics: Global Combat Support System-Army Is Supporting Requirements at
Selected Units


The Global Combat Support System-Army (GCSS-Army) is among a new generation of
information systems that are replacing older legacy systems in the Department of Defense
(DOD). The Army initiated GCSS-Army in 2003 with the intent of replacing several separate
information systems used to manage logistics at Army tactical units, such as ordering and
tracking supplies, maintaining accountability of organizational equipment, and monitoring unit
maintenance. Once fully fielded, GCSS-Army will manage $216 billion in assets on an annual
basis and, according to DOD officials, is intended to be a key component of the department's
plan for correcting financial management deficiencies and ensuring that its financial statements
are validated as audit ready by September 30, 2017, as called for by the National Defense
Authorization Act for Fiscal Year 2010.1

As an information system that supports the Army's management of its supply chain, GCSS-
Army intersects two long-standing areas on our high-risk list:2 (1) DOD's supply chain
management, which has been on the high-risk list since 1990 because of challenges related to
managing inventory, tracking materiel distribution, and maintaining asset visibility; and (2)
DOD's business systems modernization program, which has been on the high-risk list since
1995 because of the size, complexity, and significance of related modernization efforts. We
have also previously assessed the schedule and cost estimates for GCSS-Army.3

1The National Defense Authorization Act for Fiscal Year 2010, Pub. L. No. 111-84, div. A, § 1003(a), (b) (Oct. 28,
2009). Further, the National Defense Authorization Act for Fiscal Year 2014, Pub. L. No. 113-66, div. A, § 1003 (Dec.
26, 2013), also mandates a full audit of DOD's fiscal year 2018 financial statements, and that those results be
submitted to Congress by March 31, 2019.
2GAO, High-Risk Series: An Update, GAO-1 5-290 (Washington, D.C.: February 2015).
3In September 2014, we recommended that the Army update its schedule and cost estimates for GCSS-Army to fully
incorporate best practices. DOD concurred with our recommendation to improve its schedule and identified actions
the Army had taken, and we agreed that, if effectively implemented, these actions should fulfill the intent of our
recommendation. DOD also concurred with our recommendation to update its cost estimate and stated that the Army
had completed actions to improve its cost estimate; however, we stated that these actions were not fully responsive
