If a POG, awarded with a CAB (combat action badge), were to transfer to Infantry, would the soldier be authorized to wear the CIB?

No.

The term POG, is a Marine term, the Army may have tried to co-opt it, but it is a Marine term. It is used to distinguish the fact that even though every marine is a rifleman, not every marine is Infantry. The Navy and Marine Corps do not have the CIB, they have the combat action ribbon, which is NOT restricted by MOS.

The equivalent Army term is REMF, rear echelon motherfucker.

The CIB was never meant to be infantry specific, as the MOS and career field of infantry did not exist in the Army at the time of its creation. And tanks were infantry support units back in the day. It was more about the unit formation than MOS.

The term POG makes me warm and fuzzy inside. Y'all can talk about CIBs while the Sappers make the way safe for you to earn them shineys. Essayons.

No.

A POG is a POG, until that 78 GT score "grunt" pours gasoline into a diesel generator. Until he runs his/her HMMWV without oil or gets a hot meal after a week of MREs. No. He can't.
Googling "How does me look up rules for Army awards" helps.

LOL. Nope.

NO. Read criteria for CIB

“POG” is a slang term and no. That’s a big “hell” no.

Absolutely NOT!!

Not relevant to the question, but I DESPISE the term POG. I my day, it meant "piece of garbage." Any soldier (or other service member) who rates that term should be getting chaptered. Are you really referring to a REMF?

NO
