I qualified a whole GAARNG Mech Infantry BN (600 or so Soldiers) in one weekend at FSGA - M9 Pistol, M16, M60 (pre M240B), SAW - in one weekend. That is an exercise in Time Management. The local 24ID teams (now 3ID) used 2 weeks for that training. Not much training - get on line and shoot. Big goal was to get to Bradley BFV Table 12 a few months later.
