Since Vern Humphrey yelled this at Bob Allman, I hollered this in response:
 VH> We used to take an ammo box (the wooden two-round box that 106mm
 VH> rounds are shipped in) and place it about 20 yards behind the breech. 
 VH> While trainees in the stands watched, we'd light one off, and blow that
 VH> box to toothpicks.
 VH> That was one lesson that sunk in. :-)
Especially if any of those trainees has ever been on a detail hauling the
empties away.  Them damn things get heavy.  Quick.
