NCO Corps especially our model is a recent thing and one other armies want to emulate because it is working within framework of mission command. Normandy (D-Day) is a fine example of mission command: everyone knew the mission, intent, end-state and executed once they became separated. Back then, there was one radio per company – so how did they execute missions? Simple, they had to think and make decisions vs. asking what the next move is over secure net.

I would argue that you need officers like you need NCOs. They receive a slightly different type of training and preparation. A LT is executing missions and this is to ground him/her into understanding the end result of plans he will make later on, grounded in those shaping experiences.
