Answer
The USAF was formed in 1947 and the enlisted men wore a collar insignia of a "US" inside a round circle with hollow spaces between letters and circle. This collar insignia was silver color. The cap insignia was an eagle in a circle that was also hollowed out.
This branch insignia for the USAF comes from the insignia used by the US Army at this time and further back into WW2. However the US Army insignia had the "US" mounted on a solid disc made of Brass. During WW2,, there were 3 different styles. The most common US collar device was a flat disc with the US as a separate piece attached to it. Or it could be formed as 1 piece. Also some were made such that the disc was dome-shaped and not flat.
This Army collar device came from the insignia used in WW1. The discs used then were flat with the US molded into the disc. It was much flatter than the WW2 version. The collar devices and the Crossed Rifles for Infantry were first used in the uniform changes of 1904.
