Some of the stuff in it is just plain nightmarish to a 20th century infantryman. Interlocking sentry guns tied into C3 networks with all the attendant artillery, air support, etc and with snipers able to take direct control through an interface on their rifle.
Try sneaking through that sensory minefield at night without becoming red mist.
