Hank, I'm going to say this once. I have no problem with your theory on leadership, but rather the understanding of it that you portray.

What you refer to is not referred to in the german terms in the United States Military. In fact, it's referred to as the principles of Maneuver Warfare and tactics-based leadership.

In leadership, there's many factors, but we'll forgo all of those. I'd advise you to pick up some literature on it though, namely the 14 leadership traits and the 11 leadership principles. One thing you've got to remember is that there is never a right or wrong answer except the answer you give. Leading is kind of like playing who wants to be a millionaire. You can change your mind all you want, but once you say your final answer, tough cookies, that's it. The last thing a subordinate needs to be doing in any situation is changing his orders. Quite frankly, you're expendable. If your tactical situation is questionable, that's too bad. You have your orders, do the best you can with them, but do NOT disobey.

Being flexible with orders doesn't come down to just changing them on a whim, my friend. And if your career aim is to become a military officer, I'd advise you to remember that to lead one must first follow. And don't ever insinuate that just because a man is a commisioned officer he is somehow better or more knowledgeable on leadership.

Allow me to explain the chain of command. Everyone leads three people.
End of explanation.

How, you ask, does the company commander of 3 platoons lead three people, when the squad leader leads but a few fireteams?

Because there are 4 men in a fireteam, 3 fireteams in a squad, 3 sqauds in a platoon, and usually 3 platoons to a company, though there may well be 4 or 5. Interesting concept here that you actually cited yourself. Delegation of authority to the lowest man. Command becomes easier as it goes higher, actually. See, the fireteam leader actually has to individually place men behind cover, lay in their SAW, draw out the fireteam sketch, and mark lateral limits for every position they occupy. The squad leader just takes the fireteam leader's positions, maybe moves them some, and sends it up, so on and so forth.
What it really comes down to is that each level of command only talks to the level directly below or directly above them. This allows for things to move smoother and more efficiently, as having anyone lead 500 men into the fray and having to actually LEAD all of them would blow somebody's circuits, and thus get men killed. The Platoon Leader should NEVER be all up into a squad unless the squad leader sent it up. Alternatively, a squad leader heads the platoon leaders words like gospel, and offers his advice and his experience for the senior man to call upon. The squad leader should never get all up in the fireteam, and so on up and down.
The squad leader calls a meeting with his fireteam leaders, gleans them for tactical information. He can either make a decision within the bounds of HIS mission (That given by the platoon leader) or if necessary to stray, call into the PL and advise him of the new situation. Or the PL might call a meeting with the squad leaders and take their input prior to tasking them out. Either or, his call. But whatever call he makes must stick.
In truth, the difference between an officer and an NCO is nothing but paperwork. The Officer has politics to play, has paperwork to push, and administrative BS that weighs him down so heavily he wants to commit suicide. This does not make him a better or more important leader.

And so you know, anybody who's been in the military, from the lowest private to the Chief of Staff, has had more hours of leadership training and OJT than you can possibly imagine. So don't let me catch you negating enlisted men around here. I won't be very happy.

That said, your book knowledge is very good, and you're quite well learned in principle. However, you need to work on the application of that knowledge, and before you can do that, the interpretation of its meaning. Some of the conclusions you've drawn are more than a little off the mark. Now that's not to say you're on the wrong track, it's merely interpretation error, but if somebody doesn't tell you, you're gonna mess up.

Long story short, do what you're told in-server. If you have a better idea, bring it up IN PRIVATE, as one of the principles of following is don't second guess your command in public. If he doesn't listen, buckle up, grit your teeth, and soldier on as the army says. Or as we Marines prefer, go to the PX, get you a box of straws, and suck it the (Insert expletive) up.
