I don't think tracking people via facial recognition will significantly help, but some similar technologies might. Recognizing camouflaged tanks (or disturbed ground concealing mines, or flares vs engine exhaust, or...) would, though. And I don't think those techs are separable, if that makes any sense. > At this point, what is actually accomplished by the US military getting even fancier ways of killing people? From how things are shaping up, even if things come to blows b/w US & China it won't be a shooting war. It's looking like it will be similar to the cold war: neither adversary can dare attack the other, so we end up with a series of proxy wars and nitpicking at the adversary. And if you think that neither country will be able to afford to attack the other and thus stop preparing to be attacked... Well, that feels like it'll invite an attack. Not to mention that some of those proxy wars might end up being "Korea mk2" or "Taiwan", both of which would make conventional military expertise extremely valuable.
