Add it up yourself. This is from Fort Benning
http://www.benning.army.mil/infantry...ent/ATP3-21.8/
both Benning and armchair general give the same data...27 infantry + 12 crewmen + one platoon commander ....that adds up to 40 in four vehicles. When everyone but the crews are dismounted there are 3 men per vehicle......therefore there are 7 spaces per vehicle for the dismount troopers
