The critical role contractors play in supporting military operations in Afghanistan and Iraq necessitates that the Department of Defense (DOD) effectively manage contractors during contingency operations. Lack of sufficient contract management can delay or even prevent troops from receiving needed support and can also result in wasteful spending. Some analysts believe that poor contract management has played a role in permitting abuses and crimes committed by certain contractors against local nationals, which may have undermined U.S. counterinsurgency efforts in Afghanistan and Iraq.
