Battlefield Role

Fight from cover with teammates nearby to watch your sides. When the enemy fires, use their reload to take a shot and pull back.

Strengths

Your gun and armor can lead a push when they match up well against the enemy.

When to spawn

Bring it when you can hold a lane from cover. In an uptier, rely more on your position than your armor.

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
4 persons

Keep your sides and rear out of view. The lower hull and area around the gun may also be weak spots, depending on the tank and the shell hitting it.

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

Mle1910M · APHE

A practical anti-tank round when it can penetrate. Aim into the fighting compartment so the explosive filler can reach crew and modules.

Mle1915 · HE

Use against exposed crews, aircraft where applicable and lightly protected targets. Avoid spending the shot on heavy frontal armor.

Mle1935 · APC

Weapon
47 mm SA35 L/32 cannon

Use against armor and aim for crew or critical modules. A penetration alone may leave the enemy able to return fire.

Mle1935 HE · HE

Weapon
47 mm SA35 L/32 cannon

Use against exposed crews, aircraft where applicable and lightly protected targets. Avoid spending the shot on heavy frontal armor.

Ready Rack and Carry Load
