He was left holding the pieces unable to fire back while one of the Green Berets walked along the edge of the boat to get Tommy another M-60. As he was doing so, the boat made a high speed turn to starboard and the Green Beret kept going--straight into the river.
I thought that Rassman was blown off the boat by the mine. Now by Kerry's own words in the Congressional Record he says the guy fell off when he made a "high speed" turn.
It may be that this was a diffent event and different guy who was falling off his boat but this story differs greatly from the Rassman story.
Good catch.
