German infantry advance through a Russian corn field, summer 1942. The Caucasus is visible in the background and the machine gunner in the foreground, carrying the MG 34, is protected by his assistant gunner carrying a MP 38. This type of advance was nerve-wracking for the troops, since close combat could occur at any time. It was also difficult to detect mines in such terrain.
