I did not grow up in the vietnam era...but I always thought a "tour of duty" was one year....How did Kerry get 2 "tours" out of the 4-months he was over there?

Another thing, kerry must've been one heck of a soldier...here's a bit of trivia for you guys...

The military (army, navy, air force, or marines) has NEVER given out three purple hearts to the same person in only 4 months. never..Hmm.....makes you wonder.
