It makes more sense.Allies at least USF and Sov have more aggressive early gameplay. Any aggression is more effective if it coordinated just because you may concentrate more units and abilities for attack in one place to achieve success fast and with less casualties (Act of War) (Of coz defence also benefits from coordination but u cant defend everywhere in everyplace at anytime)
So the rule is attack benefits a lot from coordination
“The best form of defense is attack.” – Carl von Clausewitz
