My dad was a sniper, paratrooper in 1st Canadian Parachute Battalion in WW2.
He's told me some wild shit that he went through. Getting dropped in the middle of it all behind enemy lines to clear it out for the troops to come in. He did a few drops.
He told me that one time he and his buddy took out a concrete bunker (I guess thats what they are called, Germans hiding in it with machins guns and shit) by themselves to help the allies progress. He wasn't suppose to, but got fed up with his commanding officer and went against his orders and did it anyways. He didn't like the way the plan was, so those two did it their own way, and got the job done. I've read about that incident before, but he sure wasn't mentioned and it was all thanks to him.
Thats just one moment in the war that he told me about. He's not the type of guy to brag about it. He went there to do a job and survived through it.
