General command rating

In Medival total war the general comand rating increased the valor of a unit. But it doesnt seem as the general command rating has any effect on the valor in Rome total war.

what effect does general command rating have in Rome total war?

P.S do A.I generals with high comand rating fight better than A.I generals with low comand rating?

Your generals and captains will collect command stars as they win battles. These stars make them more effective. I shall quote CA developer Jerome Grasdyke on how stars work:
“It currently affects both morale and combat ability - we tried it for a while with just morale, but it ended up being not enough of a bonus. The combat calculations have changed so much from Rome to Medieval as to be unrecognisable, so it's no longer easy to equate stars to experience.

As a rule of thumb it's one point of attack per command rank, up to a maximum of 10, and this can become negative for very bad generals. Experience is one point of attack and one point of defence per chevron, plus a morale bonus.

The general's command also controls his radius-of-effect, which is set to 30 m + 5 m * command + 2 m * influence. This is used to award morale bonuses only, and is calculated between the actual general's position and the centre-point of nearby units.”
