Spawning random generals

[The Uruk]

How do you spawn random generals?
I want to spawn several rebel generals/captains in specific places but have the strat map model of isengard's(france) general/captain. I want the generals to have randomized names and portraits.
How do I do this?
Thanks

use the command in script:

spawn_army
faction slave sub_faction france
character random_name, named_character, age [put the age], x, y, [put the co-ordinates], label generalspawned1
army
unit blah

It needs (?) a comma before the sub_faction:

spawn_army
faction slave, sub_faction france
character random_name, named_character, age [put the age], x, y, [put the co-ordinates], label generalspawned1
army
unit blah
