A very nice and early example of the Defense of the Caucasus medal here. Steel mount on the reverse, with a high pin and typical wartime configuration. Ribbon is in beautiful condition with bright colors and very minor wear. 
 
The Medal "For the Defence of the Caucasus" was awarded to all participants in the defence of the Caucasus - soldiers of the Red Army, sailors of the Navy, troops of the NKVD, as well as persons from the civilian population who took part in the defence of the Caucasus during the battle for the Caucasus.
