This complete overhaul of the T3 Armoured Car is reinforced with tank armour. While these extra defenses lower the T12’s overall speed and handling, the addition of treads provide increased performance in less than ideal terrain.
— In-game description
The T12 “Actaeon” Tankette (also known as a MG Tankette) is an Colonial open-topped Tankette. It is equipped with a hull-mounted 12.7mm machine gun.
The T12 “Actaeon” Tankette has 1150 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 it won't last long when faced with heavy explosives or anti-tank weaponry. 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). It has Tank Armor. With it, in best case scenario, penetrating projectiles only have a 60% 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 120 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.
The T12 “Actaeon” Tankette is a well-armed and armored tankette, which is equipped with heavy armor and a gun capable of damaging enemy infantry, some vehicles and certain structures. Due to these characteristics, it is capable of shrugging off most infantry weapons, with heavier ammunition, like anti-armor rounds or explosive, being the only ones able to effectively damage it.
Tankette Effectiveness over the Course of the War
Similar to all tankettes, as soon as heavier anti-armor weapons become more common, (such as anti-tank rifles) the T12 “Actaeon” Tankette loses most of its relevance on the front line, as they will quickly be destroyed, as longer ranged weapons prevent the crew from reacting fast enough before being destroyed.
