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

What is a POG?

No.

In order to qualify for the CIB you need three things:

You need to be school trained as infantry.
You must be in an infantry unit, doing an infantry mission.
And you must be satisfactorily performing said duties.

No

Fuck NO. Outta here with that bullshit

There are NO POGs. All Soldiers & Civilian support personnel are vital, in their given rolls, to success of our country & Armed Forces. My first enlistment was 13B10 - Cannon Crewman - Field Artillery. My unit assigned me to our Supply Platoon, another was assigned to Motor Pool - Parts (TAMS Clerk), & a third as our Battery Commander's Driver. We were all 13B10s.

Hell no! Anyone asking this question is also a POG because they would know if they were Infantry. You MUST be 11-series and engaged in combat. No other MOS, except maybe 18's are even allowed to wear it. Read a manual on the wear and use of military combat awards.

Are you said POG? Strange question.

Rule #1 in the military, if you have a question then read the regulation. AR 600-8-22 is MILITARY AWARDS. Each award is unique and non-transferrable, you have to meet criteria.
8–8. Combat Action Badge
a. On 2 May 2005, the CSA approved the creation of the CAB to provide special recognition to Soldiers who personally engaged, or are engaged by, the enemy. The CAB is intended to serve as a companion to the CIB and CMB to recognize the greatly expanded role of non-infantry Soldiers in active, ground combat.
b. The requirements for award of the CAB are branch and MOS immaterial. Assignment to a combat arms unit or a unit organized to conduct close or offensive combat operations, or performing offensive combat operations, is not required to qualify for the CAB. However, the CAB is not intended to recognize Soldiers who simply serve in a combat zone or imminent danger area. Battle participation credit alone is not sufficient; the unit must have engaged or been engaged by the enemy

Rule #1, when in doubt read the regulation. AR 600-8-22 MILITARY AWARDS sets the criteria for awarding of awards. Each award is unique and they don't cross over.

No.
