Marine vet Richard Rocco developed a new skill after his combat tours: Snapping selfies of his muscled, tatted body and posting them online. He looks pretty hot stripping out of some overalls, too.

Rocco has developed quite a following, no thanks in part to a penchant for posting his sexy on Instagram. Pics with pup Rambo just make him more appealing. Whether he's packing that booty into some sexy underwear or showing off at the gym, it works. It so works.
