Breaching is a very specialized skill and it’s not practiced nearly as much as it should be. In real life it’s a critical skill that unfortunately is often just an afterthought. A good breacher can be the difference between life and death, good cases and bad cases.
I’m a retired Firefighter, a trucky at that. I never in my career had a door I couldn’t breach. Sometimes very fast, aka mule kick, some very slow, aka Partner saw. The thing with us is we weren’t worried about the element of surprise. If on a first breach attempt in a tactical situation you’re not successful, you’ve lost that element and need a second option.
It was amazing how many unlocked doors were breached. Usually by excited pumper rats. I was inner city most of my career, there were days we had two or three good housefires. It toned down by the end of my career but I stayed on the truck in the hood anyway because if there was going to be a fire it was most likely to be in my district. A lot of unnecessary damage gets done by young people with an adrenaline dump. I’ld rather have them a little too aggressive than have to go looking for them hiding in the backyard leaning on a roofman hook.
