The 213 Things You are No Longer Allowed to Do in the U.S. Army

An oldie but a goodie - my personal favourites:

22. Must never call an SAS a 'Wanker'.

77. The MP checkpoint is not an Imperial Stormtrooper roadblock, so I should not tell them "You don't need to see my identification, these are not the droids you are looking for."

170. Not allowed to 'defect' to OPFOR during training missions.
