Battlefield Role
Cover crossings from concealment. Set up the firing arc before exposing the hull; move before an enemy reaches the side.
When to spawn
Choose it for a job your team needs. After a loss, try a different route rather than driving back into the same firing lane.
Common Mistakes
- Repeating the same peek. Once an enemy has your range, move to another angle before firing again. A second shot from the same opening is easier to anticipate.
- Firing without a retreat. Choose cover you can reach during the reload. Do not cross into an enemy firing lane just to finish a damaged target.
Survivability and Armor
- Crew
- 2 persons
Protect the sides and rear, limit repeated exposure from one position and avoid assuming that a strongly armored plate protects the whole vehicle.
Keep exposed sides and the fighting compartment behind cover. Check the incoming round and impact angle in Protection Analysis before relying on the armor.
Ammunition
M-31-UK · R
Check this round’s guidance or fuze requirements in the test drive before relying on it in combat.
Ready Rack and Carry Load
- Maximum capacity
- 12 rounds
Carry enough for the route and resupply plan. A listed first-stage capacity alone does not establish a safe spawn load or prove that another rack is empty.

- Maximum reverse speed
- 10 km/h
- Power-to-weight ratio
