Thanks Eric for the feedback. I would like to ask for more detial about your answer. Do you mean the AC, CC and CSC give each "one" point of infantry to the unit in battle. So 3 bonus points?
Or do you mean that "one" of the attributes is used from AC, CC and CSC - so f.e. infantry with f.e. AC (infantry of 3), CC (infantry of 3) and CSC (infantry of 2) to a total bonus of 8?
Don't take this the wrong way, but have you read the manual yet? This is all covered in there.
With that said, each general has two "strategy" ratings. Those are his Attack and Defense. During a battle, those ratings affect the strategic outcome by determining how many units under his command are committed, whether they have entrenched on defense and most importantly how much they each count for in the calculation of who won the battle and who lost.
Each general also has several specialty ratings, which are the "tactical" ratings. These are Infantry, Cavalry, Artillery, Naval. During a battle, these ratings affect how much of a combat bonus he gives to units he is helping or commanding. For example, if he has an Infantry rating of 4 and is helping an Infantry brigade, he will add d4 to its roll to hit another unit and subtract d4 from any unit targeting his own. A general with an Infantry rating of 3 would add or subtract d3, etc.
So if an Army Commander, a Corps Commander, and a Corps Sub-Commander are all helping an infantry brigade, they all add d(Infantry Rating) to the infantry brigade's rolls to fire and to avoid being hit. For example, if they all have Infantry ratings of 3, then the Infantry Brigade gets +d3+d3+d3 whenever it fires at an enemy unit.
Note that units that are damaged will only contribute half their combat value to the strategic calculations and units that are destroyed will contribute zero to the strategic calculations. So the tactical rolls affect the battle outcome, but the Attack/Defense ratings of the leaders affect it more than any single "hit". Hence you can end up with the situation where the side that takes more losses still wins the battle.
