This is for everyone in the discussion:
According to AR 600-8022, the Combat Action Badge can be awarded once for each qualifying period (Para 8-8e(1). The qualifying period for the CAB is from 18 September, 2001 to a date to be determined (Para 8-8e).
Therefore, a person, as long as they meet the qualifying criteria, can only be awarded one CAB, regardless of if the person was awarded one for Iraq, they can not get a subsequent award for events in Afghanistan. At no time is anybody authorized to wear the CAB with a star in the oak leaves. The current time frame has not expired.
For further information on this, you can also consult https://www.hrc.army.mil/TAGD/...Action%20Badge%20CAB
. It has a Q&A area where the same question is asked:
Q: "4: Can a Soldier be awarded a second CAB for a subsequent deployment to Afghanistan or Iraq?
A: "No. There is only one period/era for award of the CAB and that is the Global War on Terrorism (GWOT). GWOT encompasses Operation Enduring Freedom (OEF), Operation Iraqi Freedom (OIF), and Operation New Dawn (OND)."
I hope this answers your questions.
