The Navy deleted a picture of one of its commanders after people online pointed out the scope on his weapon was on backward, but not before the Marine Corps got its licks in.

Cmdr. Cameron Yaste was featured on the Navy’s Instagram with a rifle in hand. Yaste is the skipper on the USS John McCain, and the branch intended to honor him. The photo was captioned, “From engaging in practice gun shoots, conducting maintenance, testing fuel purity and participating in sea and anchor details, the US Navy is always ready to serve and protect.”
