When we used M16A1 in the '80s, the drill was
On 'load' you cocked the wpn, rotated the change lever to safe, put the mag on
On 'action' you cocked the wpn,
On instant, set the change lever to fire and wait
The M16A1 never had a mag on it without being set to safe, I'm surprised there was any other drill that had the change lever in the fire position with a mag on, but nothing in the chamber
What army is this?
