For sure. My buddy has gone through 2 tours in the last 3 years. He doesn't talk much about it but when he does... just cant imagine.
The stories I have heard in my family alone make me shudder. Great uncles... one in Iwo Jima, one in Berlin in the final days, and one a B-24 Pilot.
These folks deserve so much for literally making it possible for us to live where and how we do.
