As name implies, it would be a turret whose job is to stealth nearby units / structures*
There would be limits to this power, of course.
*Comm stations cannot be cloaked
*Requires supply
*Costs K by default
*May cost ongoing resources (see below)
It's uses would be as follow:
*for turrets, a limited form of radar dampening. If not firing, cannot be fired upon
More importantly, though
*can hide certain irreplaceable structures, such as factories (for balance reasons, if they are turned off) radar dampeners, z power generators, ion cannons (if turned off) etc.
Would such a structure, even if only accessible by research, be too strong? Would it like a warp jammier need ongoing resource cost for such potentially great usage?
