Oh, I don’t know. Just read the CO’s bio. He’s had a lot of staff jobs that would have had him rubbing elbows with some very senior admirals. Given that this was a stray 3-shot burst of an M-240, and no damage was done, I figure that this will stop with the sailor (and maybe his immediate supervisor if it’s shown to be a training issue).
The most dangerous thing in the world is a Sailor with a firearm because he likely doesn't know how it works. The closest I ever got to one in back in NTC SDiego boot camp back in '67 was a Springfield 1903 with the firing pin removed...though I did have some real experience with real ones in SERE school (but cannot claim to be a very good marksman). Sailors then were best at working the sliderules that Marines couldn't figure out in a thousand years--I suspect the same is true today with higher tech gear.
