Anyone in the military have a combat deployment patch?
So, today we all participated in a ceremony where we all were awarded/allowed to wear our unit patch on our right sleeve arm. A patch here signifies that one has deployed with the respective unit to a combat zone.
This tradition goes back to WWII if I remember one of the LTs saying. Also, our battalion commander and command sergeant major was there.
