My dad was a Green Beret during the Vietnam era. He did three tours of duty there.
When I was about twelve, he described an exercise where they parachuted into the ocean at night, swam to shore, then made their way through the jungle to a rendezvous point, using only rudimentary tools, etc.
I think that qualified as air, land, and sea.
Navy Brat myself.
Never understrod my Dad’s choices until I had to face them myself.
It’s not just the military man but his whole family that pays the price for our freedoms.
