Sim training is fun.
on 2: Do the knife drill often. A buddy of mine has a training studio in his basement well equipped with a heavy bag, kick pads, a BOB, blue guns, training knives, etc. In practice we've found the teuller (sp?) drill easy enough given 21 feet or less room and a large area to retreat. The problem is in the vast majority of cases 21 feet is the exception to the rule. We practiced that particular drill down to point blank using every angle of attack. Both of us know how to handle a knife too. It was incredibly intense. We came to the conclusion that in enclosed area's at close distances, don't even think about going to the gun until you've dealt with the knife. We found the best way to do this was controlling the knife hand with both hands and pulling the guy off balance and sweeping. Once off balance and on his ass, draw and make a judgement call.
on 5: You are cops, you wear vests. Train how you fight. I did sim training in a T-shirt last time because i carry a handgun in a civillian capacity and the only time i wear a vest is on duty when i can't carry.
on 6: simunitions cut out the hero shit you get when using airsoft. People will run out in the open and take 2 dozen hits with an airsoft and laugh it off. when those sim round hit, no one is laughing, and no one is volunteering to break cover.
