No expansion without equilibrium. No conquest without control. Pursue success in serenity. And service to the tau'va. With pride. -- Shas'o T'au Shi'ur
An 'in the field' deployment of the firestorm defence wall.
From the Manual:
"The Firestorm Generator creates an infinitely high force field. Once the generator is constructed, special Firestorm Wall Sections must be placed on the perimeter of an area to be defended, just like a wall. When activated, the force field that results from these emitters is impenetrable. The Firestorm Generator consumes massive amounts of power. Because of this, it can only be active for a short period before it needs to recharge. The shield can be turned on and off at will."
