I found this on a google search. One of the stories involves a grain of wheat to rebuild the nation (who is to do this? Supposidily you are to kill yourself with the round).
Inside that truck were some matches, a razor, and a .45 pistol
(obviously a M1911A1). We were told that in case of the post being over
thrown that the last man leaving would take down the flag, climb the
pole and knock the truck off of the top, use the razor to cut the flag
up, use the matches to burn it, and then shoot themselves with the .45.
Also, the ball on top is just a ball, and the TRUK is actually part of the pulley system.
