I usually equip "myself" with an army's S+2 weapon and some sort of protection.
So like in a Skaven
army I'd have the "BFA3000" (Desolate Blade) and the "Twisted Wool Hat" (Twisted Crown)
If I put myself in my Empire
army, I'll use the "BFA3000" (forget the name of the S+2) and the "Sweater of Meteoric Wool" (figure that one out
)
However, I usually only serve as a champion or even rank and file member of my armies lately, after being demoted for poor generalship.
