Challenge #31
These are the ten questions from War Dossier daily challenge #31, of 23 October 2026, with the correct answer and an explanation for each. Today's challenge is a different one and it is free to play.
The dossier entry: SU-76, el autopropulsado más numeroso
The SU-76 was by far the most-produced Soviet armored vehicle after the T-34 itself: more than 14,000 were built between 1942 and 1945. Its light armor and open-topped fighting compartment earned it unflattering nicknames among its crews, such as 'suka' ('bitch') or 'the bare-arsed Ferdinand,' mockingly compared to the heavy German Ferdinand tank destroyer. Despite its poor initial reputation, its 76 mm gun and ability to keep up with the infantry over rough terrain made it an ever-present fire support vehicle in the Red Army until the war's end.

- Trucks, more than rail
- Exclusively on maritime convoys via the Black Sea
- Large-scale transport aircraft
- Camel caravans across the steppes
Much of German supply transport depended on trucks rather than rail, which made it especially vulnerable to the rasputitsa's mud, since Russian roads were scarce and of poor quality.
