Their research was successful and the result was 'Anthrax Beta'. The GLA even experimented in creating newer and deadlier strains of anthrax on their own. The deaths of infantrymen in its way tended to be mercifully short, but horrific, as their organs burned and they asphyxiated. A slow-moving ordinary civilian farming tractor, it was fitted with canisters of the toxic substance on the sides, and mounted a hose-like turret able to spray it at infantry over surprising distances. The deployment of this hazardous material called for the invention of some bizarre makeshift 'delivery systems', perhaps most infamously the Toxin Tractor.

The GLA tended to combine what anthrax they were able to obtain with a corrosive ooze made from an unspecified cocktail of lethal chemicals, tinted a lurid green apparently for shock value. Several of GLA related mission is noted to happen near any chemical compound containing bio-hazard. The GLA were known to tip their tank shells with small amounts of anthrax and pump their Scud warheads with toxins prior to launch.

The GLA did not adhere to the international treaties banning such weapons such as the Geneva Protocol and would implement them whenever they could. During the GLA conflict, much of the war was centered around preventing the GLA from launching their biological weapons upon the world.
