If you are talking about glider flying for the military, I don't believe West point has a club, Navy flies at a local SSA club, and the Air Force Academy Flies a standard right-hand pattern that is tower controlled and in Class D Airspace.

The Air Force's record prior to making it an enforced and strict program was not all that terrific, but since regimenting the program and beating airspeed control into student's heads, they may have one of the best safety records in the gliding world (incident per flights)...

Probably goes to show that you can fly whatever pattern you want as long ask you maintain a safe airspeed for your flight condition.
