The most useless training Marine Military Police must ever do.

I'm gonna cut the idiot Public Affairs Officer that decided to release this video after the tragedy in CT some slack.

A little, not alot.  The Marine Corps doesn't need to touch the gun control issue with a 10 foot pole and they're dancing on the line by coming out with a vid on active shooters.

Next.

If you have a Marine go madman and do an active shooter on a Marine base then you're more than likely facing a combat veteran...they better hope its not someone from Combat Arms or they're facing hell in a hand basket.  The "fast is slow" "smooth is fast" nonsense will get tossed when they engage in a CQB battle against someone that knows what they're doing.

An 03 will be slicing pies around corners and making MP's cry.

Last but not least, the truth of it all is this.

Marine MP's will secure the perimeter and once the active shooter knows that a credible deterrent has arrived then most just cap themselves.

This was trendy training, not smart training.
