This modified “Hatchet” features a reinforced fuel cell fixed to its rear alongside a flamethrower turret. This light tank can launch litres of burning fuel a fair distance, while its crew remains protected behind light armour plating.
The H-19 “Vulcan” has 1950 HP and is disabled under 30% health. It has "Heavy Armor" resistance: it can soak small arms fire, shrapnel, and 12.7mm machine guns, and it is immune to Flamethrowers. But heavy explosives and anti-tank weaponry are a real threat to it. It has subsystems that have a chance to be disabled by heavy explosives and anti-tank weaponry if hit specifically: Tracks: 30% (Anti-Tank Mines always disable them), Fuel Tank: 25%, Turret/Cannon: 25%. It has Tank Armor. With it, in best case scenario, penetrating projectiles only have a 33% chance of penetrating and doing damage. That chance goes up quickly if the armor is worn or if it is shot from up close, or on the side or rear from a direct angle, or with ammo that has penetration bonuses. It takes 145 Basic Materials to fully repair it from 1% to 100% health with a Hammer. Its health, subsystems, and Tank Armor can be instantly repaired at a Garage for 100 Basic Materials.
Similar to all flamethrower weaponry, the H-19 “Vulcan” is incapable of damaging armored vehicles, unless they are open-top, where the crew is exposed to the outside environment. However, just like all flamethrower weaponry, it is effective at light structures on fire, slowly burning them down and preventing them from being repaired until its extinguished. Special care must be taken in order to ensure the safety of the vehicle while getting close to them.
Its main armament, the flamethrower, is a niche tool. When used directly against infantry, it can become one of the fastest kill tools (right behind explosions, which will instantly kill a player). While it is tempting to charge hunkering infantry, it's better to flush them out with fire and heat. The near-nonexistent damage and quick emptying of a canister forces the crew to conserve ammunition against flammable targets. Setting enemy structures ablaze will also deny enemy infantry their use, slowly damaging it and preventing them from repairing it.
Although it is possible to use a Light Tank without a Commander, it's not recommended as it will limit your awareness on the battlefield.
