Hi,
This is Lonnie Thomas and I served with D troop from May 68 - May 69.  I had the doors on my chopper painted and got attention from Gen Ewell who was the division commander.  I was directed to paint over it but held out until the maintenance officer came out with a can of paint and started painting.
 
Glad somebody got to keep a logo.
 
PS I flew in the Long Knives.
