SF vs PE
 

Repairing tanks is possible in SF at least the tracks press T.However you don´t have as far as I know the options the fuel and ammo supply options etc that you have in PE but then SF is not the same type of game.Your command options are very limited compared to PE or Panzerfront bis for example and the battles on a much smaller scale.The game is more about individual actions rather collective ones.It´s possible that when they make their next sim Graviteam might introduce these features.

However if you make your own user-made missions with the Mission Editor which is fairly user-friendly then you can make your own imprint i.e co-ordinate artillery strikes( which you can create) and infantry attacks and make you armour and infantry move to given points at given times and even introduce airstrikes. But you have to make your own misisons for that.
