A SEAL, a Ranger, a Marine, and a Delta operator were all sitting around a fire one evening. The Marine says "...on my last tour we rucked 40 miles and killed everyone in sight." The Ranger says, "Ha! Well on my last tour we jumped into combat, rucked 50 miles, and killed everyone in sight." The SEAL says, "How about this, on my last tour we swam in, rucked 60 miles and killed every last person in sight....."
After arguing for a bit they look over at the Delta operator and he's stirring the hot coals with his dick.
