As a new player, I find it very confusing to understand where my soldiers are, where vehicles are, which soldier/vehicle is on which aircraft. How many soldiers are allowed on vehicle or aircraft. Is there a limit of soldiers per base or the limit is shared. How much is this limit increased by creating barracks?
I'm not saying that this information is not accessible, just that it is not presented to the player in an intuitive manner.
I would suggest making personnel/vehicle/aircraft management layer much clearer.
