This unit serves as a mobile walling mechanism that provides a flexible, fast deploy.

One of the weaknesses is that it often needs 2 civilians to deploy a full wall at early game, which is costy and not so reliable compare to Hard Cheese (Stargate). Another weaknesses is that these walls are affected by Cat's Mouse Magnet spell, which moves them away from their designated position.
