Oh man... whoever said not many was very wrong... I live in Virginia Beach which is basically the biggest military town on the east coast. And trust me, there are tons of "military surfers."
That being said, in my opinion, 95% of them are total kooks. They just flat out suck, and they ride some terrible boards. They seem to love funboards or like 6'8 thrusters that look like they belong on the north shore. They love to cut people off too. The worst is when some military kook just burns you on a wave, falls in front of you, and when you confront him about it, he says "No man, YOU cut ME off."
On a side note, when you see one of these said kooks in the water, (especially at your home spot) just incessantly tell them to go home. Its fun to see how aggro they get. They will immediately want to fight you. At which point you point out all the parents on the beach with little kids, and tell them that the second they throw a punch one of those parents will call the cops faster than they can say blueberry pancakes. They usually attempt to catch like 3 more waves after this before leave with their tail between their legs.
P.S. Sorry if I have offended anyone here, I have just had waaaayy too many bad experiences with "surfers" in the military.
