Grunt 

ACTUALLY...the term grunt does NOT originate from WW2 as a reference for untrained military personnel..it's a Marine Corps term for any infantry MOS due to the "grunt" made when infantry Marines would lift all their gear...throughout military history, the Marines have carried the heaviest loads into combat and have remained the most effective, intelligent, and brutal force. Marines are known for their ability to carry the most weight the longest distances...with all due respect, NO OTHER BRANCH CAN TOUCH THE MARINE CORPS...don't get mad...i said with all due respect!...and another thing POG is the correct spelling for a non-grunt...it's an acronym for Personnel Other than Grunts...

Marines who aren't grunts should've joined another branch. Don't fake the funk.
