As with all decisions, trade-offs were a necessary part of the T&E plan for the MRAP program. The first and most obvious trade-off in this case involved the heavy emphasis on survivability during DT-C1, at the expense of reliability, maintainability, and other supportability issues. The PM accepted significant risk in that some of the vehicles fielded, although survivable, may have been difficult to sustain and may have had low operational availability. A second trade-off involved the prioritization of the MRAP ahead of existing and ongoing acquisition programs. As a result of the un- forecasted MRAP T&E requirements, personnel and other resources were reallocated from some programs. Consequently, some schedules were adjusted and programs had to replace reassigned personnel; however, no program missed an acquisition decision based on changes made at the Aberdeen Test Center due to MRAP T&E requirements. In addition, the MRAP program provided a silver lining for existing and future programs with the facility and equipment upgrades it brought to Aberdeen.
