Commander Greven il-Vec,

One correction on the valor gained from the general's command (stars) rating. In the MTW single player campaign, morale has been separated out from valor gain when it comes from the general. The general's command rating affects the attack and defend combat stats, but not morale. Morale now comes directly from the general's V&V's.

Valor gained by the unit in battle or from upgrades follows the +1 att, +1 def and +2 morale formula as stated by MonkeyMan.
