Does combat cause anyone to struggle with truly believing or questioning how a God could exist?

Some turn to God, and some turn away.

I've heard that some come to the crossroads (during an engagement) of questioning their sense of what is right when faced with a combatant in their sight picture....you rely on your training and fight for those on your flanks, to the left and right, but the main priority is to focus overwhelming & accurate firepower on the target to eliminate that threat! You might thank your God after the engagement is over but for now, your ass and abilities belong to the unit!

Just a knowledge that God is a libertarian and stays out of peoples lives unless requested works for me. Bad things happen and I think that is part of his plan, in the end I'm certain it all works out.
