A Warp Stabilisation Field is produced by a Warp Stabilisation generator and acts similarly to a Gellar Field to protect Imperial ground vehicles like Land Raiders and Dreadnought walkers from assault by the entities of the Immaterium.
Warp Stabilisation generators are intricate and highly-sophisticated technology that is no longer understood in the Imperium of the late 41st Millennium. As such, they are rarely used, as they are nearly impossible to replace if damaged or destroyed.
