Nokta FoRs Gold, a Gold Cube, 2 Keene Sluices and Lord only knows how many pans....not to mention a load of other gear my wife still doesn't know about!
The "Combined Arms and Tactics" or CATD group is out of Fort Benning, GA., and
your buckle is associated to that group. You might send a photo of it to the
CATD unit (if still operational) and ask them for a more specific ID.
