lol mini, you just had to dig at me once more, did you. I won't comment it further, since I was right and the matter is settled.

To the subject. Now I see how it works, as you explained it with person A B C and D. Ok, it seems to be quite complicated from the first look, but actually it's not.

So, i just pick some names, Qvintvs could be leader of 3 legions.
He can elect his frieds as he likes to be the commanders of these 3 legions and fight at his orders. He decides himself if he has a strict style of leadership or if his commanders can act autonomous. His friends just need to fit the requirements of a Legatvs.

So he can say, Avlvs, Tiberivs and Sextvs, you are the commanders of my legions, oh and Marcvs, Caivs and Titvs, you could be Tribvni in those legions, if you like.

Could Avlvs, Tiberivs and Sextvs elect Tribvni themselfes? I guess yes.

The most important point is, that after Qvintvs term ends, the chain is like erased and new elections have to be done.

BUT Qvintvs could run for the same post again, and if he'd be elected, the chain of command stays as it is.
