"Fielded to the Army in 2005, the Crusader 155 mm self-propelled howitzer (XM 2001) and resupply vehicle (RSV) have taken fire automation to new levels. The three-man crew can automatically take care of ammunition transfer from the resupply vehicle; ammunition inventory management and selection; fuze setting; ammunition loading and fire control without ever leaving the vehicle. It has a firing rate of 10-12 rounds per minute, a range of 40-50 km and can reload 60 rounds in 12 minutes."
