Soviet Army and Air Force Insignia

Hello,
Here is some of the insignia used by the Soviet Army and Soviet Air Force.
(Left to Right)
Top: Communications, Construction, Armor
Bottom: Bands, Engineers, and Chemical troops

Next, are some more insignia used by the Army and some Air Force.
Top: Motorized Rifles (embriodered on wool), Motorized Rifles, Border Guard
Bottom: Airborne Troops (Embriodered on wool), Airborne Troops, and the Soviet Air Force

I don't know why some were embriodered on wool, possibly for officers, I don't know. Next up, is something that is kind of hard to find. It is the patch for the Soviet Military Commisaries (Ministry of Defense).

If you have anymore, feel free to add them here. Thanks.
Andrew
