The no liquor rule must be an Artesia thing as it is not in place at GLYNCO or Charleston SC.
I after a shooting (interrupted crime in progress) involving an inservice class, Charleston (and I believe Glynco) now allow in-service students to keep their guns in individual gun lockers at the gate house to facilitate carrying off base.
No go for basic students of course.
We lost 3 from my FLETC FITP day one and none after that. It was at FLETC cheltenham which is a “day only” campus that mostly does inservice driving and shooting for DC based FED LE so no dorms, no cafeteria and no checking weapons.
