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...

Referring to US Marine Corps Infantry personnel. GRUNTS are anyone with the MOS beginning with 03 as in 0311 (Riflemen). The term originating during World War II to abbreviate the term "Ground Reinforcements Untrained," referring to tons of troops being sent to combat with little training. The term has taken on a more affectionate meaning for our killers in the Marine Corps Infantry today.

The term GRUNT also refers to those doing their time commitments and getting out during the Vietnam War; as opposed to Lifers who were career Marines.

The term POG is the opposite meaning "Personnel Other than Grunt"
