There's a few issues with this. First, u.s.m.c is an artist. The tag marine corps is largely the United States Marine Corps, but not exclusively.
'Corps' is maybe generally US-centric, difficult to say without looking at all the other Marine forces' full titles --- which for reasons that should become quickly apparent, I an reluctant to do, yet the more famous Royal Marines in Britain are also [ presently, they started off as a Maritime Regiment in 1664, and have been 'Light Infantry' and a Brigade in the past ] a Corps. Even older, France's Marines were always very formidable, like the rest of their military and started part in 1622 and part in 1627.
Wiki has 61 present countries [ I dunno if any terrorist groupings have Marine components, such as ISIS, the IRA or Shining Path... ] and 25 historical countries including Rome, the Byzantines and the Austro-Hungarian Reich, with Marines; I would be revolted if the word devolved automatically to mean the USMC.
