The ladderman is a very fast unit that spawns with a ladder upon recruitment. He can set up his ladders against an open wall section or a gatehouse by issuing an attack command from the ground. Moreover, he can also quickly push one down while standing on higher elevation, making for a quick overwhelming of undefended wall lines. Any unmounted unit can utilize ladders.
Ladders may be pushed away by any troop standing nearby. Units on top will fall to their death once this occurs. Ladders may also catch fire or be damaged by catapulted rocks.
The ladderman is recruited at the engineer's guild or a siege camp. Here the unit can equip an additional ladder when he has none at hand.
