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, next question please

NO

No. Plus the CAB is dumbest thing ever come up with.

The CIB is not a uniform decoration for someone just because they an infantry unit. There are very specific criteria that need to be met prior to being authorized to wear the CIB! Those requirements include being assigned to an infantry unit during such time as the unit is engaged in active ground combat and actively
participate in said combat

Seems like a question that could be easily answered by simply looking at the regulations. But common sense should also tell you that you can't.

Different awards, different criteria, different people. You would still be required to wear the CAB if you went to a promotion board for example or a soldier of the month or year board. You have to have an Infantry MOS and serve in an Infantry Role normally for a certain period of time in Combat, although that is probably waiverable. Be proud of who you are young soldier, because that enables to have the future that you can create. Same for the EIB and the EFMB and if they actually got the ESB going -- no idea just haven't seen it in AUSA, you have to have the MOS and be assigned in the position.

No
