 Up-armored HMMWVs were not designed to be armored cars like the M1117, which are designed to withstand hits from small arms, mines and rockets in front-line combat units.Soldiers who used them, and some members of Congress visiting Iraq favored them over other mine protected vehicles.As of mid-2007, 1,729 vehicles were delivered or under contract with many being dispersed not just to MPs but numerous other military units including the Iraqi National Police.
