Funny video. But anybody that's done the "helo dunker" knows how little fun the crew is having right now.
My unit spent a long weekend at NAS JAX doing all sorts of unnatural water events including the dunker, treading water for long periods of time with multiple high pressure fire hoses directed straight down onto us, and full combat load swimming laps, as well as others whose memories I have probably repressed.
Some dark-green Marines had a really bad weekend.
