We have armed guards at them all..
I doubt the schoolhouse is very secure once you pass the main gate.I can’t speak to the main gate but I can say the secondary gate to this particular base is very well guarded and a very well conducted search is done of your vehicle each and every time you pass through it . You get out , turn over your keys and you get them back when they are done . We spent two weeks there moving “ stuff” off base for them .
