The HYDRA Flamethrower is one of the advanced weapons developed and used by HYDRA during World War II before harnessing the power of the Tesseract.
History
During their first actions as a special weapons division of the Nazi Schutzstaffel, the scientists of HYDRA developed several advanced weapons. However, after Johann Schmidt and Arnim Zola managed to harness the power of the Tesseract, most previous weapons were discontinued to favour the newly created cannons and assault rifles.[1]
One of these few weapons that were still used was the HYDRA Flamethrower, which was used by many soldiers in HYDRA Headquarters when Captain America raided the base.
Two soldiers managed to surround Rogers before entering the compound using their weapons, and managed to buy enough time for HYDRA soldiers to surround Rogers and take him to Johann Schmidt.[1]
Later, one of these soldiers managed to slow down Captain Rogers while pursuing Johann Schmidt, but the soldier was killed when Agent Peggy Carter fired to the backpack of the flamethrower, making it to explode.[1]
