As you've seen in previousarticles, diagrams showing weak areas of enemy tanks were pretty common in the Red Army. However, these diagrams were usually produced as a result of thorough study and live fire tests. Sometimes diagrams had to be produced with less information, and thus ended up a little bit more vague, like these ones drawn up in the early stages of the war.
To start, the Pz.Kpfw.III tank. The USSR had some experience with this vehicle, but the information is still pretty vague. The gunner is instructed to fire an anti-tank cannon (presumably a 45 mm one) from 1000 m or closer at the areas highlighted in red. Areas highlighted in blue (vision slits and the cupola) are vulnerable to bullets. The reader is also instructed to throw grenade bundles under the tracks and Molotov cocktails on the engine deck.
