Had an uncle that served on a Navy minesweeper prior to D-Day. He said it wasn't really bad duty. Well except for the Germans shooting 5" at you for target practice. lol
Never been under shore battery fire but I'd wager it sucks.
That's how I got interested in Frog men and Buds. Read about them going in wearing a swimsuit, planting charges on the steel gizmos the Germans put up to stop landing craft. And of course that group morphed into Navy Seals.
I'd have never made it, hell they had to almost throw me off a 12 meter platform in bootcamp and that was in broad daylight. I always thought that "Shallow Water Sailors" stayed in water you could walk back to shore in,,,bastards. lol
