Battlefield Role
Watch a crossing from cover and leave room to pull back. If your gun has limited traverse, avoid close fights that force you to turn the whole vehicle.
When to spawn
Bring it when you have a useful lane to watch from cover. Leave an isolated position if the enemy starts taking control of the map.
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
- 5 persons
Watch for enemies coming around your side. Open-top vehicles also need protection from aircraft, artillery and explosive shells.
Positioning
Use a firing lane with side cover and keep the hull facing the threat. Leave space to reverse without exposing a flank.
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
M72 shot · AP
Use against armor and aim for crew or critical modules. A penetration alone may leave the enemy able to return fire.
M48 shell · HE
Use against exposed crews, aircraft where applicable and lightly protected targets. Avoid spending the shot on heavy frontal armor.
M61 shot · APCBC
Use against armor and aim for crew or critical modules. A penetration alone may leave the enemy able to return fire.
M89 · 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
- Maximum capacity
- 60 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
- 17 km/h
- Power-to-weight ratio
- 16.3 hp/t
- Engine power

Top speed is not cross-country pace. Check the reverse route before taking a firing position.
