My ex wifes Grandfather got a purple heart on Iwo Jima and was picked on about it by his buddies for decades. He didn't like to mention it because although he was very proud to be one of a handful of Army on Iwo, he got his purple heart for a twisted ankle when he jumped into his foxhole not knowing his best friend had got there first. So, he jumped on his best buddy then the poor guy had to carry him to the rear with his purple owie, where the medics listed him as wounded in action. I am sure John Kerry would not have been embarassed by the medal.
My Maternal Grandfather was an old man when WW2 started (late 20s). The doc that processed him, told him that he was 4F because of piarhea (gum disease). His response was "Well hell, I don't want eat the damned Japs, I want to kill em". Turns out that the Doc was just trying to offer him an easy out. They ended up pulling all his teeth and giving him dentures so it wasn't a problem after all. Then they put him in the Navy and he told them he couldn't swim, they said it wasn't a problem, they guaranteed they'd teach him to swim. He was about 90 when he told me this story and he leaned over and said "you know, I still can't swim"...LOL Poor bast"%" ended up on Destroyer Escorts and the USS Dennis went through about every $#!% storm you could suffer through in the Pacific on a tin can.
My other Grandfather hopped a ride over the hump in a C-46 and from North Africa to South Africa in a C-47 at treetop height. His favorite story though was about the C-46 that hit a flock of vultures and the two locals who cleaned the ground and burned vulture out of the engines for two bits!
I own firearms not to fight against my government, but to ensure I will not have to.
