4 years active duty in the USMC Air Wings, as a logistics/emarkation specialist, and 2 year reserves with HQ Co for an infantry battalion. I freely admit to being a remf. Funny thing is my civilian friends think I'm some kind of bad @$$ former Sgt of Marines. I've never ever claimed to be infantry.
Sometimes you have to explain to people it's a game, not trying to represent real life, but for pure entertainment. I was relating an experience my character in Rae's game had to a non RPGing friend who got annoyed- "He should have died from hypothermia, there's no way he could have survived that." I had to explain that some situations are resolved by die rolls regardless of how risky they are, and apparently Lady Luck was with the character that day.
