The best branch of service for broad jumping is the Navy. The other branches get the leftovers. Most of the BM's swab decks and chip paint and paint the ships. It's no fun refueling ships in rough weather, lot's of hard nasty work.
Check into Special Opps. 1140. Lots of opportunities in that classification. You can go Underwater Mine Warfare or salvage diver or EOD. When you get out of service you could be a diver on an oil rig or salvage diver, (Treasure), or get an EOD job with the LEO Bomb Squad. There's all kinds of possibilities , C3Shooter might even give you a job in Demo.
Have fun seeing the world and remember to take lots of pictures and the most important thing is don't try to be a hero and come home in one piece.
