Soviet army cap rare?

I recently found this Soviet army cap at a flea market and wanted to ask if you could tell me more about it than the seller (age, rarity, whether it might be worth anything, etc.). Because for some reason I can't add any pictures, here's a link: https://www.ebay.de/itm/315628305643?mkcid=16&mkevt=1&mkrid=707-127634-2357-0&ssspo=1xaszzjct6-&sssrc=4429486&ssuid=1xaszzjct6-&var=&widget_ver=artemis&media=COPY

Tank duel between the German Reich and the Soviets. Who would win?

Let's assume an open, slightly hilly area. The tanks drive towards each other (approx. 5km) away. There is no air or infantry support.
