following testing, a first order for 1,200 mrap category 1 maxxpro vehicles was placed by the us marine corps systems command on may 31, 2007 for delivery by february 2008. however, as the u.s. army research and development laboratory is overseeing the entire mrap program, it is unclear which branches of the us armed services will be receiving the vehicles, and in what numbers. the contract was worth over $623 million, making it then the biggest mrap contract to date. the us marine corps plans to replace all hmmwvs "outside the wire" in iraq with mrap vehicles.
