I have had several SIMunition training days. One was an active school shooting scenario the others were traffic stops and clearing a house.
I would agree with XD in SC about training with SIMs if you get a chance (DO IT). I think were the best training days I have ever had. You're using a real gun shooting real ammo at a real threat. You get to see how you would operate under some pressure too (close to real world).
XD in SC, sounds like you got a taste of the life of an LEO. It's fun and scary at the same time isn't it? Sorry to hear you took one in the throat.
Have fun and stay safe, state6three8
