I remember that in the psx version of the game you could "deactivate the battle view". This is quite difficult to explain, but i'll try (sorry for my bad english xD)... You could directly take control of the unit, or the group, selected. The view centers into one unit of the group (like in the pc version when you press the spacebar, but without changing randomly to another selected unit): you could "
drive" this unit with the directional buttons, while the other units selected follow your movements. The pointer disappeared and a cross hair appeared to target an enemy (which you could select) and make the units of the group attack it. So, you become the "commander" of the group, which follows every movement. For me, this was one of the best features in the game, cos it let you have a better control of a battle.
Here is screenshot of this type of view:

The ahead tank is the one which you directly command (you can zoom in to make it a third person view on the unit, and you can change the "commander" unit with one of the group).
I think that this option should be added to the pc version, too...
