Situation: On virtually all of my fortresses I am able to recruit each turn one commander and one, count em, one regular troop. I assemble the most powerful armies I can. They consist of bands of 24 commanders (the maximum number of commanders you can select when in the same province) and not much more than 24 troops. A battle is joined, 12 troops are killed, half the army, morale checks are made, the whole force routs, commanders and all.

Now change this situation. I make half my commanders troops. I put them in with the regulars. Their unit morale goes up a bit as does the overall 'staying power' of the troop component due to the significantly tougher 'troops'. The same battle is joined, less than 12 troops are killed, less than a third of the army, much fewer morale checks are made, the army does not rout. Also because I no longer have 24 commanders to stack, I can double the density of the concentration of my forces, so the battle is no longer a mere 24 troops and 24 commanders. Now it is potentially 72 troops and 24 commanders, 72 really tough troops. Now 'there' is a chaos army.
