Medium vehicle very effective against all vehicles. Fast movement speed, light armor.

The M18 Hellcat Tank Destroyer is a USF tank destroyer unit. In skirmishes, it is available from the .

As the name implies, the M18 is specialized as an anti-tank unit. Its main cannon has the the highest penetration at all ranges compared to any other USF unit, making it reliable against even heavily armoured targets like the .

This unit combines strong anti-tank firepower with good mobility. It features fast speed similar to the and , making it very manoeuvrable. This makes the M18 an excellent tank hunter unit, as not only does it have the firepower to reliably damage armoured targets, but it is capable of moving into various positions effectively, allowing it to to chase and retreat with ease. This is reinforced by the M18 having the Flanking Speed ability by default, allowing them to get a significant burst of mobility at a moment's notice.

Just like the aforementioned vehicles though, it features far lighter durability than the , making it very vulnerable to all kinds of anti-vehicle weaponry. As such, it is best treated as a fast 'glass cannon' unit, requiring careful micromanagement to ensure it can perform without being destroyed quickly.

As a downside to being specialized for anti-tank duties, it is not very effective against infantry by default. It can be upgraded with an additional MG at a Munitions cost however.

At veterancy level 1 it can choose between the active ability High-Explosive Charge or the passive ability First Strike, granting it either anti-infantry/garrison utility or a strong ambush bonus. More info can be seen below.

If the is constructed the M18 can benefit from additional upgrades, including gaining access to the HVAP Round ability which increases its damage and penetration temporarily.

Veterancy Abilities

All USF units can choose between one of two veterancy abilities specific to them, upon reaching veterancy level 1.

  • High-Explosive Barrage: Active ability. Despite having the same name as other artillery barrages, this ability does not work the same way. When activated the M18 fires direct shots at the target area, similar to attack ground at a faster interval. These rounds deal greater area of effect damage but have reduced penetration, making it effective against infantry and garrisons but fairly ineffective against vehicles. Overall a fairly niche ability one can grant to the M18, allowing them to have a cheeky way of dealing with stationary enemy infantry. Like other barrage abilities it can be cancelled prematurely by issuing a new order like moving or attacking, placing it on cooldown.

  • First Strike: Passive ability. Once the unit is stationary and out of combat for several seconds (around 5-7 seconds), they will gain bonuses toward their first shot from this position. An indicator will appear above the unit to signify if First Strike is ready. These bonuses includes +25% damage, +50% penetration, and +50% accuracy. As the name implies, this is an excellent ambush or defensive bonus, making it so the first shot from the M18 is capable of immense and practically guaranteed damage against enemy vehicles. Due to its ease of use and powerful bonuses, this tends to be a popular veteran ability choice and allows the M18 to punch far above its weight, allowing them to threaten even heavy tanks at long range, and overall start fights with an advantage. This ability technically has no cooldown but since it requires the unit to be out of combat, after firing the unit will need to move out of combat to regain First Strike.

  • Flanking Speed: Active ability. After activation, the unit gains several buffs for a short duration. This includes +35% speed and +50% acceleration, as well as-25% received accuracy only while moving. As the name implies, this ability is great when a burst of speed is needed. The significant bonuses make it very easy to flank and manoeuvre for the duration, and as a bonus the unit becomes harder to hit while moving too.

  • HVAP Rounds: Active ability that is only unlocked via the Specialized Munitions upgrade available at the . When activated for a Munitions cost, the M18 gains +20% damage and guaranteed penetration for a short duration. This is a straight combat boost that not only increases raw damage on hits, but the guaranteed penetration allows the unit to fight even the heaviest of armour.


  • The M18 Hellcat has the highest penetration values at all ranges compared to all other USF units, enabling it to fight against heavy armour even at long range.

Change Log

1.6 'Coral Viper' April 2 2024

The current Hellcat is too efficient when dealing with more expensive vehicles in head-on fights. The change is meant to focus the Hellcat as an anti-armor vehicle that uses its speed to disengage or maneuver after getting an accurate, high damaging shot off.

Flanking Speed is also being locked behind an upgrade as we want the Mechanized Support Center to be the primary way for the US to access vehicle abilities.

  • Long-range accuracy increased from 0.04 to 0.045   

  • Reload time slowed down from 4.5/4.75 seconds to 5.25/5.5 seconds  

  • Now unlocks Flanking Speed when Rearm and Refit is upgraded. Flanking Speed no longer available by default.
