I had mine today. Sort of sadly ironic considering the circumstances in California, but it was fun at least. I managed to almost piss off the instructor, though. Apparently we did real well; nobody got shot. They use Simunition rounds on us (9mm cartridges loaded with paintballs). But they do it in three scenarios; escape, barricade, and fight. In the first, we have to escape the building. The second, we have to barricade ourselves in a room and ensure the shooter can't get in. The third is we have to fight the shooter. They train locally; each scenario is five minutes long, as that is the average response time for Security Forces. The first two went alright (although in the second, I managed to destroy one of their vacuum cleaners using an extension cord to tie the door shut, made them a a little irked). But the third one, the fight scenario, was sort of interesting. We loaded a set of wall lockers against the door (we had to create an obstacle, but one the shooter could get around), and flipped the furniture over. The guy managed to get in the room, but the lockers got a bit tilty on him. One of our Master Sergeants who weighs about 250-260 and all muscle got him against the wall. My troop got a shoulder in his gut and it was my job to get the gun away from him. Which is where things got dicey; he had an M9, but he had it pointed towards someone else. So I got my hand over it and managed to get the safety engaged. Then I got my fingers in his wrist and got the gun away. Flipped the safety off and held him at gunpoint on the ground until "Security Forces" arrived. Apparently they weren't a fan of that lol. They didn't say we couldn't, and I figured why the Hell wouldn't I? Apparently it's the first time anyone's ever done that. Which is odd to me, but oh well. AST in general is a bit of a joke; its very controlled and there are lots of rules, which they thankfully acknowledge, but it was a crap ton of fun. Thinking of helping them with training; they need aggressors to shoot at the cops and the SOF guys that train out there, so maybe I'll do that. Also, since none of us got shot, they had two full mags of Simunition left, and offered to let us shoot it....Hell yes I shot it. They set up a terrorist cutout at the end of one of the halls and let us go to town. It was a good day.
