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

Yes, when he earns it. You can't trade one for the other.

If this individual did not engaged hostiles in combat with the infantry unit he is assigned to, then no!

No and when I was in we were all a TEAM.

Short answer: Hell No!

No, the "POG" as you so reference (why the name calling? isn't a soldier just a soldier?), would have to earn the CIB as an infantry soldier outright. The CAB is a separate badge, plus he could not wear both at the same time.

All you have to do is read the regs dealing with the qualifications for various badges and medals. Too easy, especially for those who are always attached to their phones.

Regarding a PFC's use of the term "POG:"
1.) If you haven't deployed to an actual combat zone, you don't get to cast shade on others who have, possibly several times.
2.) Be careful who you insult.... (See the picture)

Absolutely not! You must be an Infantryman and awarded the CIB to wear it.

No they would still wear the cab

What the? Don't go asking those questions in a line unit.

No. Not unless he went back on another combat tour and received the CIB as an infantryman. ALSO- Only ONE of 5 awards -- CIB, EIB, CMB, EFMB, or CAB-- can be worn on the uniform at any time. A soldier could, theoretically, have 5 uniform shirts with each Badge on it, but no 2 can be worn at the same time.
