The Flammenwerfer 35 could throw burning fuel up to thirty meters away from the user. It had a number of different manufacturers. It was used to clear out trenches and buildings. It held about 11.8 liters of oil mixed with tar lit by a hydrogen torch.
The Flammenwerfer 35 was fairly heavy, weighing in at 35.8 kilograms, and had a total burn time of about ten seconds. Similar to Soviet flamethrower crews, German users of the Flammenwerfer 35 and 41 series often painted their flamethrowers to look like a backpack and rifle to avoid the operator being picked off in combat. Flamethrower operators were generally protected by fellow infantrymen regardless because of their importance in the clearing of enemy positions.

The Flammenwerfer's design is based on a previous 1918 German flamethrower used to clear trenches. The Flammenwerfer 35 and all of its variants were used by German forces throughout World War II to clear pillboxes and other fortifications in much a similar role to its predecessor. Many of these flamethrowers were used on the Eastern Front during Operation Barbarossa and other operations. Here, they proved to be quite effective in clearing out enemy troops quickly and effectively, paving the way for advancing infantry and armor. As such, production of the Flammenwerfer 35 and its variants continued until the end of the war with thousands of units being produced.
