Light vehicle effective against infantry. Can damage light vehicles and shoot down aircraft. Cannot fire at targets directly in front of the vehicle. Can be damaged by small-arms.

Note: This unit is a variant of the regular that can be built in skirmishes and upgraded into this form. This form cannot be built directly in skirmishes.

Once the base truck is upgraded to this form, in exchange for gaining a weapon and slightly higher side/rear armour, it loses all of its previous utility. This includes no longer being able to transport troops, tow weapons, reinforce squads, and re-crew abandoned weapons. It also loses Support Veterancy and thus must fight to gain veterancy much like any other unit. The Polsten conversion also replaces the veterancy 1 ability with a new offensive ability.

This is one of very few UKF armaments that can effectively shoot down aircraft. Against ground targets, it is most effective against infantry and light vehicles. However, it comes with an awkward caveat of not being able to fire directly in front of the vehicle, and the turret faces the rear rather than the front. This means that facing the truck's rear toward targets is the best way to utilize its weapon.

Somewhat weaker than other equivalent AA vehicles when it comes to direct anti-infantry performance, its shots have area of effect explosions and thus can still be effective against infantry in cover. While it may not have the same killing power as some other light vehicles, it comes at a lower cost comparatively and can be attained quite early through the ML 4.2-inch Heavy Mortar call-in from the Indian Artillery Battlegroup. Upon reaching veterancy level 1 it gains the active ability Suppressing Fire which grants increased rate of fire and suppression when activated at the cost of penetration.

This unit benefits from the Light Vehicle Training upgrade available at the .

Veterancy Abilities

  • Suppressing Fire: Active ability granted upon reaching veterancy level 1. When activated, temporarily grants the Polsten truck significantly increased suppression and rate of fire, at the cost of penetration for a duration of 30 seconds. Essentially an on-demand offensive buff to deal more damage to infantry while also enabling suppression of infantry (as normally it will not suppress on its own), but generally decreases its anti-vehicle performance while active.

Change Log

1.6 'Coral Viper' April 2 2024

This change is primarily to reduce the impact of a CMP 15CWT rush when the player goes for the 4.2 Inch Heavy Mortar which could arrive before proper anti-vehicle counters can arrive.  

  • Polsten and Medical upgrades now require the Platoon Command Post
