Bridging Ladders
From ZombieSquadWiki
Bridging ladders are heavy-duty metal sheets that have been stamped into a shape that allows them to support the weight of a vehicle and also acts as a traction device. They have two purposes, the first is to act as a bridge across holes and small ditches, the second is to provide a traction device under the tire while on soft slick surfaces like mud or wet sand.
