Had a great uncle who never spoke about the war at all. Learned at his funeral that he received two bronze stars and had four tanks shot out from under him. Most never survived the first I was told by a fellow who served under him for a few weeks of the war. Replacements tended not to last long and he never forgot my uncle taking care of him. He got wounded when the fourth tank got hit. Only two survived and he was one of the lucky ones. Went to hospital and came out shortly after the war ended. Funny thing was he knew every persons name and where he was from in the tank. Said he had visited each of the families and had talked with my uncle within the last year. Never knew and I was close to my uncle.
He just never spoke about it and if asked gave a short, vague answers like he could not recall or it was not very important. If fact most men I know who served never speak much about what they did or saw. Those who speak volumes are often just full of crap. There are a lot of things men do not want to clearly recall and I respect that in them.
