my brother was a vietnam vet and i recently met and befriended as it turns out another vietnam vet. who happens to be an amputee (leg) not from the war but after but then who is to say, that war left many scars unseen. any really loud noise and if my brother had a few drinks in him, he would dive under a table...never the same. my brother lost his leg as well, not in the war but after, but who is to say. maybe he lost it somewhere out there, hit by unseen shrapnel, he lost more than just a leg.
