German Infantry Crossing the River

Improvisation and ingenuity were characteristic of the German Pioniere, even though their makeshift solutions could not always be fully appreciated by the men using them. This improvised footway, built using medium-sized inflatable boats, planks, and timber, enables the infantry to get across the river, but judging from the look of the machine gunner in the foreground something more stable would have been appreciated.
