Charge 7
Master Gunner
This was always the prime gag to pull on a newbie. It's related to "box of quadrants", "bubble pump", "Left handed monkey wrench" and other similar jests but this one had the advantage of sounding very real and important. You select your victim and tell him that so-and-so (best if somebody not in the immediate area but requires a long run to reach and should be on the gunline) has the "cannon report" and so-and-so (should be as far away as possible from the person first sent to thus ensuring another long run) needs to have it. This can go on for quite awhile. I went to the Chief of Smoke, the Gunnery Sergeant, the motors chief and finally the Battery Commander who took pity on me for the fun the XO had started. The Cannon Report is "BOOM!" that is the report or firing sound of a gun. I hope they still do this one. The uniform was the old "pickle suit" when I went through this rite of passage.
