Gents:
"A Leader cannot be singled out as the target of an attack unless he is the only occupant of a hex. Therefore, it is advisable to keep your Leaders stacked with friendly unit(s) of his command. Each time a hex containing a Leader is attacked, there is a 4% chance he will become a casualty." - CS Manual
"...a Japanese Leader is twice as likely to become a casualty as a Leader of another nationality (thus, an 8% chance if stacked with a friendly unit, or 20% chance if alone in a hex)." - CS Manual
So, based on the above, non-Japanese leaders would have a 10% chance of becoming a casualty if attacked while alone in a hex.
I have played games in which both the commander (Foot) and (Mot) retreated after direct fire while alone... but I would think the percentage chance would be higher for motorized commanders?
