I also remember our survival swim. My whole platoon was supposed to jump into the water, link arm to arm in a line with our heads toward the shore. I noticed armed sailors on the circling LARCs, so I asked the Gunny what they were for.
"Oh nothing, just a precaution." he said.
"From what?" I asked.
"Look" he continued "When you join the line get in the middle .... you may get to the beach before the sharks get to you!"
Then he shoved me off the ramp into the water.
"Noooooooooooooooooooo!"
