The ST1 is a Tier 8 progression Tank Destroyer under Zhang Feng's dealership.

History[]

Class: Fire Support Vehicle
Developed: 2010s
Service: 2014+ (allegedly)
Vehicles Built: 12-36 (allegedly)
Operators: Venezuela, Nigeria, Argentina (allegedly)

The ST1 is, simply put, a fire support vehicle on ZBL-08 chassis – one of two in fact, the other one being the ZTL-11 tank destroyer. The difference is that the ZTL-11 was developed by the Chinese for limited domestic use, while the ST1 is purely an export vehicle. Like the ZBL-08, the ST1 was developed by NORINCO. Instead of the IFV variant turret, the ST1 carries a large two-man hydraulics-traversed turret armed with a low-recoil 105mm rifled gun that can fire NATO standard shells.

Not much else is known about the ST1 – the prototype was unveiled in November 2014 at the Air Show China expo. NORINCO advertised that the vehicle could become a part of rapid reaction light brigades in combination with the ZBL-08, a prospect that Venezuela found appealing – according to several sources, along with the 2014 order of approximately 40 VN1 IFVs, the Venezuelans ordered perhaps a dozen ST1 fire support vehicles with the first of them being delivered at the beginning of 2015. Other sources claim that Argentina ordered perhaps two dozen of the ST1s at the same time. The first Argentinian deliveries allegedly happened around the end of 2014, although sources differ and this may not be true for the fire support variant. Nigeria, on the other hand, definitely purchased a small number of ST1 vehicles in 2020.

Vehicle Traits[]

  • Marksman: This vehicle can fire advanced ammunition from its accurate weapon, allowing it to destroy enemy armor at long distances.
  • HESH Rounds: This vehicle can fire special Squash Head rounds. These are extremely effective against angled armor that is typical for Soviet tanks.
  • Amphibious: This vehicle is more resistant to taking on water, allowing it to traverse wider rivers or lakes.

Description:
This ability temporarily turns your vehicle into a deadly sniper by increasing its camouflage and accuracy. However, it also prevents you from moving and makes your turret traverse much slower.

Conditions:
If your vehicle moves even a little, this ability will deactivate or becomes impossible to activate.
