My grandson when in Spec Ops had a regular routine, where they would wait for a moderately rough surf at Camp
LeJeune, and take the Marine Spec Ops out, and have them stand in a boat and pick off bottles, that churning in the distant surf.
After their second deployment, the man who "had his back" while in close urban combat, went on to train snipers shooting from choppers.
My grandson was interested in Joining the CG, before he chose the Marines. his plan was with the .50 cal on drug interdiction crafts.
The way it worked out though...his .50 was mounted atop a Humvee.
