Due to the Allies' extensive use of infantry raids, the Soviets developed the anti-personnel minelayer. This vehicle could place small mines at positions where the Soviets predicted that the Allies were likely to move their troops as back doors to Soviet bases. The minelayer itself was armoured enough to take a beating, but was light enough to reach respectable speeds. It could carry five mines at once and could refill at a service depot for free. A single mine could kill any infantry unit except Volkov and Chitzkoi. A minelayer may crush infantry under its treads, but otherwise possesses no real armaments.
