The Devitt Ironhide Mk. IV has 1950 HP and is disabled under 20% 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: 25% (Anti-Tank Mines always disable them), Fuel Tank: 20%, Turret/Cannon: 20%. It has Tank Armor. With it, in best case scenario, penetrating projectiles only have a 30% 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 135 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.
Light Tanks (LTs) are used to assault and flank enemy defenses. They benefit greatly from having infantry support to protect them.
The Ironhide has modified tracks that assists with mobility during snow and rain storms.
They are vulnerable to Anti-Tank Mines. Although a single mine won't kill them, it will cause big damage and always disable their tracks leaving them vulnerable to enemy Infantry with Anti-Tank weapons.
Enemy infantry with Anti-Tank Sticky Bombs also represent a danger because they have a good chance to disable the tracks as well.
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.
Standard Equipment Loadout
Like with every other armored vehicle, the crew should ALWAYS equip themselves with a Gas Mask and multiple Filters to avoid dying to Gas Grenades. Additionally, they should bring a Hammer and Basic Materials to repair the tank. These tactics can be buffed by wearing either a Tank Uniform or an Engineer Uniform.
Trivia
The Devitt Ironhide Mk. IV is likely based on the French Cavalry tank the SOMUA S35 or its predecessor the Char D2.
The Devitt Ironhide Mk. IV has one of the lowest disable percentage of all tanks, and the lowest of all Light Tanks, with a 20% disable percentage.
