Game description from the publisher:
With the Allied forces heralding formidable units into the fray, Axis players will want to expand their armies to include a walker with multiple cannons for a broad range attack or a laser cannon to target Allied squads. The forces in the Dust Tactics: Light Panzer Walker expansion can be customized to either Heinrich or Hermann, both offering advantages for any Axis general to bring onto the battlefield.
With one of the most deadly weapon systems seen since the beginning of the war, the Panzer AufkclarerLaufer 1-A, aka "Heinrich" can crush an entire squad, whether or not it’s equipped with heavy armor. Heinrich’s incredible firepower derives from its four powerful FlaKvierling cannons. The Panzer AufkclarerLaufer 1-A is also versatile enough to use against lightly armored targets or engage enemies from a great distance, due to it being a light and agile vehicle.
The Axis’ newest light footed anti-tank robot, Hermann, elicits the same uneasiness in your opponent as Heinrich. With a revolutionary laser cannon Hermann can easily destroy targets much heavier than itself. Entering into a long engagement? Partner Hermann with your other Axis units, like a Recon Grenadiers squad, to both protect it and utilize it for a lengthy battle. If you’re looking to annihilate your opponent early in the game, find Hermann a secure position and use its sustained fire to waste any Allied armored unit.
