Toxin tractors, as their name suggests, were ordinary civilian tractors refitted with crude armour plating and, more importantly, multiple tanks of toxin and a toxin-spraying turret. Toxin tractors were capable of clearing buildings garrisoned by the enemy by spraying a compressed liquid that vaporizes into a poisonous gas. Unlike Flash-bang grenades or Dragon tank fire, however, the toxin does not instantly kill every infantry unit in a building, but rather one at a time at a very fast rate. When stationary, toxin tractors could be ordered to contaminate the area around them.
