This is a USMC base right? Sheesh.
I don't know why MPs are the only ones that go around armed on a base. I'd think in the interest of preparation, more would be carrying.
Then, instead of a SHelter In Place (or SHit In Pants), a general alarm can be sounded.
Yep, pass out rifles and ammo. Attention, live fire drill. Shoot anyone not in camouflage
