re: Three armed men invade your home at 2am. What do you do?

Grab AR with extra mag (mounted overhead in my closet) & Glock 19 (bedside table). Wake up GF and tell her to do what we've practiced for, which is position her behind bed in back corner of bedroom with shotgun aimed at the door and tell her to get on speaker phone with 911. Walk out of bedroom and lock door and get on a knee in the hallway right outside of room. There is one hallway that gets to my bedroom and Im at the end of it so I just sit and wait. Instruct GF to shoot anyone that comes through door besides me.
