The Army wants a Bradley replacement big enough to hold a 9-man squad, which is now considered the minimum squad size needed. The Bradley forced mechanized infantry to split squads into two vehicles and the Army doesn't like that. Do we really need mechanized infantry squads to be that large for mobile warfare?
One method to reduce the squad in the vehicle is to have virtual gunners manning remote weapon stations on the vehicle. See "Reachback for the Squad" in Infantry magazine.
