Improved generals bodyguards

[Folcumbane]

I have once get those improved generals bodyguards.. when I was playing Parthia. It was a sad moment when I had to use heavy cavalry instead of skirmisher cavalry.

[Craterus]

My general is still accompanied by chariot archers but I know there's such thing as Egyptian general...

Why don't I have that unit? The Romans have had their reforms because I took on a Scipii army with loads of Urban Cohort and Legionary Cohort...
