not sure what you are asking... but
we are broken into 5 geographcal unified commands (edited to fix that I am a dipshit that just sat through a briefing on the proposed new UCP and still got this wrong!)
U.S. Northern Command (NORCOM)
U.S. European Command (EUCOM)
U.S. Pacific Command (PACCOM)
U.S. Southern Command (SOUTHCOM)
U.S. Central Command (CENTCOM)
and 4 functional commands
U.S. Joint Forces Command (JFCOM)
U.S. Special Operations Command (SOCOM)
U.S. Transportation Command (TRANSCOM)
U.S. Strategic Command (STRATCOM)
obviously SOCOM handles Special Operations... when you ask what makes a SOCOM whatever, I can only assume that you are refering to a piece of equipment that is refered to a "the socom something or other"???
If so, that is what they call marketing (it sound cool), you see it all the time on here, the terms Operator, SpecOps, etc just tacked onto whatever pice of equipment someone is hawking...
In truth, it means nothing more than one company got to the name first...
