Before my gramps passed on, he would tell me stories of how he watched them dump tanks, jeeps, and other equipment in the ocean off the ships. He was part of the under water demolition, what is now formed into the navy seals. His team had to go over to them islands and dive looking for some kind of floating bomb or something to dismantle so the boats could land. I wish I was old enough at the time to remember the stories he would tell.
