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

Nope. I have an infantry e5 in my platoon who was literally attached to some engineers on a deployment to Iraq and since he was attached to them (even though he was 11b), he got a CAB, not a CIB.

Funny,... Really ? OF COURSE NOT !

If he earned a CAB he should wear it. As for a CIB he must earn that before he could wear that.

No, you would continue wearing a CAB until you earned a CIB (then you get the choice on which to wear) You would also have to be assigned to an Infantry position performing Infantry duties to earn the CIB. Check AR 600-8-22. https://armypubs.army.mil/ProductMaps/PubForm/Details.aspx?PUB_ID=1003738

I don't personally think it's a silly question, especially from a young PFC wheeled vehicle mechanic. He doesn't know infantry, or the award system of the army. Remember, there's no such thing as a stupid (or silly) question. I learned that in the Army

1st off I would comment of the term "POG" especially when it comes from a service member with an MOS that would him firmly in the middle of that group. However the answer to you question is NO. Look at it this way, let's a convoy is rolling out to a FOB. On the way it gets ambushed and a firefight breaks out. It gets intense and lasts 30 minutes. All 11 series Soldiers in the convoy would earn a CIB, any non 11 series would earn a CAB unless they were in the medical field where they would earn a CMB all for being in the same engagement.

No. One of the requirements of the CIB is that the soldier is assigned to the infantry branch.

Good luck.

If he/she earned it whats the issue. You should be proud of anything you've earned. As a soldier you should respect another soldier until proven not worthy not assumed not worthy.

At first I wasn't going to respond to this but since I am now, If this POG has a CAB, this means he doesn't have an 11 series MOS. That being said, if the POG changes the MOS to an 11 series, that DOES NOT MEAN the POG gets to wear the CIB UNLESS, the POG is SERVING in a COMBAT THEATER WHILE IN said 11 SERIES MOS.
