I am now. Say we set up a system that funnels enemy aircraft and infantry into a certain area, say, the direction of the ocean. From there, we give them a bit of leeway in, install weaker guns to let them draw within range. In terms of firepower, thats where we turn the tides, reveal our secrets. If they don't bugger off at the AA batteries, they will perish with whatever secret weapon we put in place. I'll take it, but I need 3 other things: A suppression field of sorts, one that can nullify the effects of an EMP, and with an emergency backup, should they fail. A radial EMP to knock out ships from the sky. It needs to last long enough to put them in or near the water. We'll put other batteries in there as well. Deployable Dissolvers in the city, items that can nullify the effects of chemical warfare.
