Well any gunfighter worth their salt is going to try and get close in-order to get you in the kill-zone. I am not firing from a distance unless I need to, to many things can go wrong. Even the best sniper misses. No, I want you as close as possible while still keeping me safe. 

Bravo Melon on your interrupts . . . that is the proper use of them. You act when you see the action begin. The truth is there are a lot of myths surrounding guns and gun fights. Being shot at, even in training exercises is not fun, but it teaches you to use cover. Simunition puts the fear of God into you when you get hit, and makes you remember the CQB techniques designed to keep you alive.
