Battlefield Role
Use covered side routes to create crossfire. Scout when fitted, settle the gun before firing and change position after revealing the flank.
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
- 3 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
3BK17M · HEATFS
Use against armor where the jet can reach the crew. Composite armor and ERA can defeat it; fences and other obstacles may trigger the shell before impact.
OF-412 · HE
Use against exposed crews, aircraft where applicable and lightly protected targets. Avoid spending the shot on heavy frontal armor.
BR-412D · APCBC
Use against armor and aim for crew or critical modules. A penetration alone may leave the enemy able to return fire.
3BM25 · APFSDS
Use against armored vehicles. Aim through crew or critical modules; the narrow shot path makes placement matter.
3D3 · Smoke
Place smoke between the enemy and a crossing or retreat route. It blocks sight; it does not stop incoming fire.
Ready Rack and Carry Load
- First-stage capacity
- 12 rounds
- Maximum capacity
- 40 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.
Mobility
- Maximum forward speed
- 70 km/h
- Maximum reverse speed
- 21 km/h
- Power-to-weight ratio
- 27.6 hp/t
- Engine power
- 455 hp
- Weight
- 16.5 t
Top speed is not cross-country pace. Check the reverse route before taking a firing position.
