The T5 “Percutio” has 1250 HP and is disabled under 30% health. It has "Light Armor" resistance: it can soak small arms fire and shrapnel, and it is immune to Flamethrowers. It can soak 12.7mm machine gun fire but not for long. Heavy explosives and anti-tank weaponry are an extremely dangerous threat to it. It has Tank Armor. With it, in best case scenario, penetrating projectiles only have a 85% 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 100 Basic Materials to fully repair it from 1% to 100% health with a Hammer. Its health and Tank Armor can be instantly repaired at a Garage for 100 Basic Materials.
The T5 “Percutio”, like all wheeled armored cars, is a lightly armored car, but it is designed to combat enemy armored vehicles. In terms of mobility, it has decent off-road speed and relatively fast on-road speed, which gives it greater flexibility to where it can fight effectively. Along with its slow-turning turret, it is better to stay on roads so the crew can react faster if they're being flanked. Additionally, due to its low health, a single anti-tank mine will nearly destroy it.
Due to its decent off-road speed, it makes a good ambush and harassment vehicle, as its good general maneuverability on the battlefield makes flanking and gaining advantageous position is easier compared to other armored cars. Keep in mind, its still faster on-road than off-road, so road travel is better when trying to cover large distances.
AC Effectiveness over the Course of the War
Similar to all armored cars, as soon as heavier anti-armor weapons become more common, (such as anti-tank rifles) the T5 “Percutio” loses a lot 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. However, due to its armament, it can be a formidable opponent when operated by a competent crew (though this depends on the 20mm penetrating).
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 vehicle. These tactics can be buffed by wearing either a Tank Uniform or an Engineer Uniform.
Depending on when the crew fields this Armored Car, these equipment may not be unlocked. If they are unlocked, the crew should equip them so they are not easily killed in combat.
Trivia
In Latin, "Percutio" means "I am striking" or "I am beating".
Unlike the “Typhon” ra.XII, the ATAC's weapon does not have an HV modifier, which means it shoots standard 20mm ammunition.
