On the Don river Front

Hungarian 20 mm anti-tank cannon in firing position along the Don river in Soviet territory; September 1942.
The Solothurn S-18/100 20 mm anti-tank cannon was a German and Swiss anti-tank rifle used during the Second World War. It had a semi-automatic action in a bullpup configuration. As a result of its large, powerful ammunition, the gun had a tremendous recoil, and its size made portability difficult. The feed was either from a five or (more usually) ten-round magazine that was attached horizontally to the left side of the gun.   

Anti-tank crew in waiting

The timing of his visit coincided with the third major Hungarian-German offensive against the Soviet bridgehead of Uriv-Storozhevoy; early September, 1942.
