A little more to the story. That was primarily a USCG mission. The SEALs were in theater and shopping for something to do, asked to do it. The coasties told one of the SEALs 'hey, you are wearing too much gear.' SEAL told him to piss off, he knows what he is doing. SEAL was being butt-pushed up the ladder, which was about 4' or so above the side of the boat, hand slipped off the rung. Fell between the big boat and the smaller VBSS craft. Buddy went in right after him.
Guy who told me is not one for RUMINT or tall takes, so I believe him until something says not to.
