Siege Shield
From Warhammer 40k - Lexicanum
Siege Shields are large armoured shields mounted on the front of Imperial siege vehicles. In addition to helping protect against incoming fire, these large dozer blades allow vehicles to push aside debris and rubble without putting the vehicle at risk. Perhaps the most notable Imperial vehicle equipped with siege shields is the Space Marine Vindicator.[1]
