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 favor the newly created cannons and assault rifles.
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.
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 at the fuel tanks of the flamethrower, causing it to explode. They were discontinued after HYDRA's defeat at the hands of Captain America and the Strategic Scientific Reserve.
