The easiest way to determine when a poster will be made is to look at the fighters' uniforms. I don’t know about the USA, but in the USSR the weapon was used for a very long time. For example, SKS (Karabin Simonov) in the armed guard troops (VOKHR, they guarded cargo, warehouses, etc.) and in the air defense troops met until the mid-1990s. A similar situation persists in all armies of the former Warsaw Pact. For example, you can look at Polen, who, using Soviet technology from the 60s, say that they will seize Ukraine and the Russian city of Smolensk. This is ridiculous!)
