that is only a quarter of it. Much bigger is the impact of situational awareness. EVERYTHING in x kilometers from the front is seen. So much so even rotating troops in and out of trenches or medivac are an ass. as you need to find a way to have covered approaches, as thanks to cheap thermals even night does not protect you anymore, or have robotic helpers carrying supplies or wounded in and out.
