Det-K qusetion

[C46thVA]

I was recently looking at the SFA Korean Chapter website and found some interesting photos. Among them are several showing SF soldiers wearing ROK camo uniforms at work and at social functions. The practice seemed to stop around the time BDUs begin to appear.
I was wondering if anyone could tell me if this was "authorized" or was it something done away from the eyes of Big Army ? Some interesting pocket patches were in evidence as well.
Either way they looked damn sharp!
