And then he had to run over to help them BY HIMSELF and they only fought beside him because they could see how hard he was fighting, NOT because he gave them an order.
Guy had no power in Shinra. He had STATUS. But status is NOT the same as power. He was a glorified attack dog who won people over through his reputation. But not because he actually had the authority or rank to command them.
Military and SOLDIER are different departments. Sure Lazard steals Heidegger's best men, but Sephiroth can only be a stubborn little shit who gets what he wants when it comes to SOLDIER. Not infantry

Sure, he’s got those “unofficial 1st class privileges” as they’re so fondly labeled (thank Lazard’s leniency) like refusing missions, but he has to commit treason by subterfuge to get what he wants for a reason. SOLDIERS were dogs with fancier collars.
I see SOLDIERs as a SWAT team. They can’t command the army and they still have to obey their orders.
