Scrolls that collapse enemy trenches, used to bury the Bloc's southern positions after the first engagement.
After the southern engagement, Tran's 102nd Bulwark Battalion and Boomer's 106th Bloody Leeches fill the existing enemy positions with Fill Trench scrolls before settling back into their own trenches, and they wreck the remaining Artillery Batteries at the same time.
The scrolls deny the retreating The Bloc forces any prepared ground to fall back into, though they also mean the crawlers give up on looting the bodies floating in The Acid Trench, which they have no time for.
Engineering consumable used to erase enemy trench lines on the southern front.
