Thanks a lor Maksimus,
I didn't pay attention to this line general_unit_upgrade. So next time I play, when the Marian Event comes, I suppose the general unit will change from consulares to singulares.

But if I am here with the question, is there any other way to change the new general bodyguards? I saw that lots of factions in Eb have 2 types of generals. Do all depends on Marian event or can they be changed by script. An d if so, where should I look for changes? ib EBBS script?
