The Ivich Hierarchy is thought to be like a pyramid of power. The very top being Ambrose, since he has the most control/power over it all. The further you go down until you eventually reach the bottom is where the new recruits/trainees are. The people at the bottom of the hierarchy have no say in anything.
It's thought that the closer you are to the top, the more you truly matter within their army. The lower in power, the less you matter.
It's unknown what it takes to gain power or respect in their army, but it's known for a fact it isn't easy. In order for you to get anywhere within their organization, you need to have all of your emotions stripped from you and you need to be fearless of anything that comes your way. Zero emotion.
