As I've said before, it can work, but is usually more hassle that it's worth. You are not on the same level as your fellow soldiers any longer. Some of them will still see you as their buddy and will challenge what little authority you actually have. You have no real authority, but you can serve as a platoon leader or XO if they don't have officer in the positions. I recommend SMP cadets find another unit, even another company in the same battalion. That way, you make a fresh start and they don't know you as PFC Snuffy. If you have good relations with your unit, you might be able to make it work. I guarantee you will have some "leadership challenges", however. Might be good training in leadership for you. If it works, more power to you. I've been there, done that and most times it doesn't work out very well. Just remember, your old squad leader is now under you. Old NCO's usually don't like that very well. Good ones will STFU and drive on, but others are not so well behaved.
