After all, field Marines had to be processed, fed, sheltered, supplied, resupplied, medically cared for, counseled, paid, entertained, (if it was safe enough) and damn near anything and everything else by REMF Marines; They were the grease that kept the war wheel turning.
These "all-area" Marine's name derived from "Rear Echelon Mother Fu...uh, well, you get the idea." Their battles were often against enemies unknown to most; generally, rear echelon command was efficient, well disciplined, and professional but there were those certain Marines who seemed adept at creating boredom, tedium, and petty bureaucracy.
Yes they had cold beer and other "bennies" not available in the field, but hey, they never asked for the damn job of baby sitting the "FEMF" Marines, it was their duty; somebody had to drink the beer...
