When I think scenario training, this comes to mind;
Then you don't understand scenario based training (not stated sacastically but as a simple statement). The video claimed to be a BB demo/test.
Let me give an example of a system that is a form of scenario based training. It involves firearms and the LEO's on the board will understand I'm talking about the FATS machine (FireArms Training System). This is a screen made of a type of neopren (sp?) that you can shoot live rounds at. The screen is dialed into a computer that can branch-chain the scenario. On the screen are actors, like being in a movie. Some scenarios are shoot and some no-shoot. You interact with the actors on the screen, such as verbal commands/direct orders etc. Depending upon your actions, the computer changes the situation 'in-flight' so-to-speak to make it realistic and unpredictable. If it is shoot situation, the computer records where the shots went, whether it was considered a good shot and the actors respond appropriately (perhaps they fall down, perhaps they continue to fight/shoot/attack, perhaps they fall down but still return fire etc). There are thousands of scenarios and each one can change on the fly so you never know quite what to expect. They could obey your commands and the situation is over. That's realistic. They could defy you or cuss you or attack you. That's realistic.
This system has evolved to be so realistic that rookies literally come out of the room sweating and shaking due to the stress and adrenaline. Sometimes where behind them with lights flashing and sirens blazing, or we're yelling at them or whatever. Anything to make it as realistic as is safety possible and still provide valuable training.
What this does is give them exposure to a broad variety of experiences that they can later draw upon if faced with someting similar. As an example, if anyone has ever seen the training video, "Surviving Edged Weapons" they'll recall a training situation where an officer walks into a room but doesn't know the situaiton. A man draws a knife and begins to violently attack. Most officers backpeddled from the man and attempted to draw their sidearm despite not have enough distance to do so. Many were even trying to draw their sidearm will falling backward over their own feet. No one was successful in drawing their sidearm or successfully defending themselves. So better training needed to happen such as not to be so dialed in on drawing the sidearm in situations in which there is neither time nor space to do so. Looking for better, more viable options. Perhaps going hands on, perhaps seeking a barrier between you and the attacker, perhaps using something else easily at hand as a weapon. Often times we'll video tape training and the person will watch themselves afterwards for review and see what, if any, mistakes were made and what could have been done better. Then run the scenario again.
Just as importantly is the situation that never starts. By practicing de-escalation and having that as a viable tool when viable is preferable to fighting. I remember a long time ago as a rookie I was charged by a violent EDP (emotionally disturbed person). In my best command voice I loudly ordered him to stop and get on the ground, ya' know, like we do in all the movies. Well the guy actually stopped and fell to the ground, spread eagle. I didn't know what to do at that point! I was all jacked up and ready to rumble and here this guy actually followed my commands. Now what do I do? Took a few seconds before I realized I should probably cuff him up. The point is that prior to that there was not really any training in what to do if the guy actually stopped his attack and listened to you. As a result, I insert this sort of stuff into what I teach. So some scenarios don't necessarily have to go to a hands-on conclusion and that's good training. Best way not to get hurt in a fight is for the fight not to take place. Isn't as Rambo or sexy...but too be honest, I'd take it every time I could get it. Same thing with evading the fight or simply moving to the side and shoving him as he barrels towards me. When he lands on his butt, if I can get to a door and close and lock it...well, again, that's a viable option and the situation doesn't have to go any further as I'm safe. And sometimes it's going to be a knock down drag out fight for you life.
Exposure on the front end may mean a happier ending on the back end.
