The Department of Defense (DoD) is acquiring two new tactical wheeled vehicles (TWV): the Mine Resistant Ambush Protected (MRAP) All Terrain Vehicle (M-ATV) and the Joint Light Tactical Vehicle (JLTV). The $12.5 billion M-ATV is for use in Afghanistan; JLTV is the future replacement for vehicles like the High Mobility Multi-purpose Wheeled Vehicle (HMMWV). This report assessed: (1) DoD's progress in rapidly acquiring and fielding M-ATVs; (2) JLTV's expected features and cost compared to other TWV; and (3) the extent to which the current plans for M-ATV and JLTV are consistent with the services' TWV investment strategies.
