You are The Pilot of a Mill. $$ Air Craft.
You feel You are taking Fire. Or at least think You are. You go on the offensive.
Friendly Fire, Yes, it has does and will happen as sad as it is and will be.
I am sorry that I cannot remember the NFL Player who was there and was Killed "By Friendly Fire".
But, these are real people with real guns who may want to kill You! So, if push comes to shove, You fire back!
It is great to sit back and second guess if You have never been there.
Actually, it makes no matter where it was, it happened. It is regreatable to lose any life.
It does happen!
