While many just talk about the Marines going from the Winchester 97 Trench Gun in WWI, to the Winchester 12 in WWII and the Mossberg 590 and Benelli M4 today, for years the Corps fielded a specialized version of the Remington 870, dubbed the M-870, Mark 1, complete with a bayonet lug forend over a lengthened mag tube. These guns are highly collectible when encountered in the wild today.
As for Kitty Hawk, one of the Navy’s last conventional supercarriers, she was decommissioned in 2009 and is awaiting disposal. The Navy recently said she will undergo a drydocking in early 2021 at Puget Sound NSY’s Dry Dock 6 to remove sea life in anticipation of being moved to the breakers. She long outlived shotgun-wielding Marine Dets, which were pulled from flattops and disestablished in 1998.
