ok I need help on somethings, first of all I create an army unit, the ones which can create an army but I dont freaking know how to take a unit away from an army and add a new unit. For example I add 3 tanks in a army. But i want to take a tank unit away from the army and add an infantary.
Also how the hell do you put fighters and bombers on Aircraft carriers, what button do I have to press?
Lastly how the hell do you do amphbious assaults by marines or assault by paratroopers. I place this marines in those landing crafts but I only can land them and not conduct amphobious assaults on a city godammi!

I hope you can reply this man. thx.
