General's Bodyguard improvements?

[Gryphon]

The governor's palace of huge cites apparently enables "improved general's bodyguard"

What exactly does that mean?
in terms of looks?
abilities?
strengths?
Do they ever get to ride elephants?

... Basically, it means you bodyguards will "update" to more heavier type, just like the bodyguard in custom game.

i was wondering about the improvements as well. How do you cause these improvements to occur? I've been playing as some of the barbarian factions that have the same thing but i've never noticed an improvement to the general's men.
