The rally and autorally:
The units do thier best to rally at the end of your last turn if auto rally is set on in preferences. The commanders may well fail to do very well at that!. Or you as the player may have used up all the rally attempts in your turn. They dont get any "free" rallies out of thin air!

Then there is an enemy turn where they may have thier status adjusted by any enemy action. That's after any auto rally.

Naturally, since it is now your turn when you have control of your toys then you are perfectly free to rally them - because its your turn.!

So dont expect your troops to be all warm and cuddly, just because auto-rally is set on in preferences. It just uses up any free rally attempts on any units that have suppression and have free rallies.

Setting auto rally off simply skips that - and I cannot see why anyone would leave auto rally off, quite frankly.

Cover:
The "C" key does not "place them in cover" - It makes infantry dive into the grass, hopefully breaking any enemy LOS (if they have LOS on you). "Taking Cover" is an action which costs you MP and might make your unit unspotted. It is not a status.
