It occurs to me that there is no anti-recon promotion. Of course, there has never been an anti-recon promotion. This wasn't an issue in vanilla, because recon units weren't at all prominent... but it is here, because we have a whole line of recon units. As such, for game balance reasons, it makes sense to include an anti-recon promotion... it puts recon units on the same level as every other unit, which can be countered so. I'd suggest Vigilance for it's name.
