Topic: Security Central / Bus assault training

I was recently put in charge of my facilites CERT team. I work for a private correctional facility in Texas and the trainning lets just say is not to where I think it needs to be. I used to be on a Marine CQB team and training is very diffrent there than with at CERT team. I am trying to conduct a bus assault scenerio with my CERT team and having alot of questions on what would be the best approch to do so. If there are any suggestion please let me know.

—Scenerio- Officers are getting ready to transport inmates from facility to court or to another facility. An unarmed officer makes his way toward the back of the bus to conduct a headcount. Two or more inmates take the officer hostage. Now the CERT team is deployed to take back the officer and the bus. My first thought when thinking of this drill was to gas the entire bus and restrain everyone which is a given. But when i pitched the idea to my assistant warden he said it was a great idea yet he want diagrams and written out procedures on how this would be done. If anybody has conducted this type of trainning before please help me out, and just be mindful that this is taking place inside the facility and no type of fire arm can be used.

Respectfully Sgt. Mendoza
