[Double Naught Spy]

I assume that the non-hostile person is someone you are trying to save? If so, then you are doing hostage rescue. Unless you have no other choice, call the professionals. If the non-hostile person is not important to you in some manner, why risk your life trying to perform a the task of dynamic entry for which you probably are not adequately trained?

Contrary to IamNOTaNUT, you can hit what you don't see. The problem there is that you may hit the non-hostile person and that may not be able to hit the targets you want to hit in an efficient manner. Spray and pray tactics work that way, but that also means you are firing without knowing your target or what is beyond your target. Remember, you are responsible for every round you fire and the consequences that result.
