The warriors on the battle field, the men in the shit. The ground re-enforcement unit for any armed forces.

Grunt is an acronym used during WW2 for troops who had no formal training, or skills. G-general, R-replacement, UNT-untrained,...GRUNT, as they had no special training, they were given rifles and sent to the front.
Grunts do all the fighting.

Try not to waste your shotgun ammo on Grunts. They're not worth it.

Grunt is basically a non twitch sub to somebody. (Mostly used in YRG and YRG affiliated servers) Grunts are the lowest of ranks you can have. Grunts mostly have no rights and get banned left and right.
Some people say "Grunt Lives Matter" to make the Mods appreciate them.

A front-line soldier.

A grunt is anyone, regardless of rank, who digs his or her own foxhole, performs front-line tasks, handles live weapons and ordnance and duties in combat zone and risks his or her life.

The opposite of grunt is REMF (Rear-Echelon Motherfucker), a desk job military person off the combat zone. If the definition of a grunt is one who digs his own foxhole, a REMF is anyone who sleeps between clean sheets.
To be a grunt in the Marines is the pinnacle of macho image

Grunts.... Age of the Corps, 234 years of ass kicking, ball busting, days of death and destruction. Where every day's a holiday and every meal's a feast. We are A.L.I.C.E. pack operated, M.R.E. feed, beer cooled, green amphibious monsters who thrive on war. GRUNTS, Ooh-Fuckin-Rah!!!
Those Marine grunts are some baaaad motherfuckers!
