Something that unfortunately tends to fly out the window when stress enters the equation is clear thinking.
It seems like everybody studies, practices and sometimes even downright fantasizes about “dynamic entry” and building clearing when often the best thing to do is slow the F@#K down and think about the necessity of it.
Going into a building after an armed and barricaded man or clearing your home in the middle of the night is probably the most dangerous thing you could ever do. You need to seriously consider the necessity of attempting it before you do it. Ask yourself, is there really a need to “go in”? Is someone in danger?
If you know someone is inside a building, armed, alone, and not ready to surrender, what is the hurry? Why would you need to “go dynamic” and risk getting shot? Perhaps there IS a reason, but you really need to figure out what that reason is first and be able to articulate it. If you go in and get yourself or someone else killed, what will your explanation be for your decision? If you and your wife are in your bedroom and you hear someone in the house (you KNOW someone is in the house and there is nobody else living in the house with you), what possible reason is there to go out looking? Arm yourself, call 911 and bunker down. It may even be a good idea to announce what you have done quite loudly. ..the fact that you are armed and have called the cops that is.
In lone gunman barricades there is typically an attempt made to make contact with the bad guy and negotiate. If that works than you are golden. If the bad guy decides to not respond then an option is to knock in the front door and wait outside.
This approach allows you to continue (if necessary) with what is called a “limited entry”. You don’t necessarily have to breach and clear every room in the structure. You simply have to figure out where the subject is.
If the bad guy manages to wound, or even worse kill one of you, will “going dynamic” to get him be a good solution if it results in more of the good guys getting injured or killed? I don’t think so. Evacuate and deal with the new situation.
And while it is a fact that you want to minimize the noise you make so that the subject can’t track your movement or location, that does not mean that you cannot call out commands or instructions. I have seen officers trying to “stealth clear” in situations where the better option would have been to stand outside and call the bad guy out. Even if you get a “F$%K YOU!!” in reply you at least can get an idea of where the bad guy is.
It is vital to remember that all situations differ, you need to be flexible and decide what the best tactical response for your particular incident is.
