Defense Budget: Obligations of Overseas Contingency Operations Funding for Operation
and Maintenance Base Requirements

Since September 2001, Congress has appropriated approximately $1.7 trillion to the
Department of Defense (DOD) to fund overseas contingency operations (OCO).1 Since fiscal
year 2010, DOD has requested, and Congress has authorized and appropriated, separate
amounts for both operation and maintenance (O&M) base requirements2 and O&M OCO
requirements as part of the annual budget cycle.3 Both amounts, however, are appropriated into
and executed out of the military services' existing O&M accounts. Congress directs how both
O&M base and O&M OCO appropriations are to be obligated by designating specific amounts at
the subactivity level in conference reports or explanatory statements accompanying annual
appropriations acts. On occasion, Congress has directed that O&M OCO appropriations be
used to support base requirements. For example, in fiscal year 2015 Congress directed that $1
billion of O&M OCO appropriations be used to improve DOD military readiness, including
increased training, depot maintenance, and operations support for installations-requirements
that are generally supported with O&M base appropriations.

1DOD defines contingency operations as small, medium, or large-scale military operations, including peacekeeping
operations, major humanitarian assisted efforts, noncombatant evacuation operations, and international disaster relief
efforts.
2Base requirements are those costs that would be incurred whether or not a contingency operation took place. O&M
base requirements encompass continuing annual costs of DOD's routine operations, including operating support for
installations, training and education, civilian personnel, maintenance, contracted services, and defense health.
3Prior to fiscal year 2010, supplemental appropriations generally provided additional budget authority needed by DOD
for contingency operations and were most often identified as Global War on Terror (GWOT) rather than as OCO
funding. Supplemental appropriations are funds appropriated in addition to those already enacted in an annual
appropriation act and provide additional budget authority usually in cases where the need for funds is too urgent to be
postponed until the enactment of the regular appropriation bill.
