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

AR 670-1 is required for the correct answer to this question. Yes the non combat MOS Soldier who arrives as a non Infantry Soldier can wear the CAB if earned, He or she would have a lot more respect in the Infantry unit, if said person was to earn the EIB they hold more prestige in the Infantry Units in my Eyes. Takes a little more effort to earn it than a CIB. CIB can be awarded for just showing up in Combat I have seen this personally.

This question has a simple answer. If any soldier has orders awarding something, he wears it; if not he does not.
If he engages in combat, as an infantryman, in the future, he can earn a CIB. I got out before the CAB was created, so I do not know if a soldier earning both (at different times in his career) could wear both on his uniform. I am sure there is an AR that addresses that subject too.

Astonishing that people ask such questions easily answered by referring to the relevant regulations

Proof that there actually are stupid questions. To win a CIB requires having an Infantry MOS assigned to an infantry unit, in an infantry MOS.The CAB is awarded to other than infantry soldiers to put recogn0<h0⁰

So I have been out for 20 years....I knew of the EIB and CIB....what is a CAB?

A POG with a CAB is no longer a POG.

Byron Skinner. Back in the day to qualify for a CIB besides being in the field and engaging in hostile fir you had to be an 11B MOS by completing Infantry AIT. EMs 11B’s through SStg. E-6 qualified and officers through and including 01,02 & 03’s In short you were to have engaged in Infantry Combat as a member of a rifle squad for EM’s or as a Platoon Leader or a Company Commander. At the end of the Vietnam war a lot of CIB’s were recalled as wee as a truck full of Bronze Stars for combat that the individual was never involved in as an Infantryman. The only qualifying MOS’s were 11B and 11C (Dismounted mortar) and in some instances 11H (recoilless rifle Dismounted) In may units this policy was not enforce and every Cook, Company Clerk and Mechanic sported a CIB. The CIB was established in early WW II to distinguish the Infantryman who had been engaged in Combat from other soldiers. I guess the popularity of the award is so high that the non Infantry are jealous, but we never saw these guys in a fire fight. I’m proud to be a second generation in out family to have qualified and was awarded the CIB. My late got his in western France January 1945 at the Comer Pocket in the Vogue Mountains, as a member of K Company 3/409 Infantry 103 Infantry Division.

Sure after he is in Combat with an enemy force

Quick answer, no. When I was in-country, non-airborne qualified replacements were assigned to the 82nd and 101st Airborne. They wore the shoulder patch, but that didn't mean they were authorized to wear jump wings too.

What is a POG?

Your awards don't change because you go to a new unit.
Would you wear a CAB if you had a CIB and went to another MOS?
