Hehe, sounds like fun.
It's a little different here, I think. combat troops here are called (I believe that is the only proper translation) "warriors", and in order command warriors, you must be one yourself. for example an infantry troop goes through basic training, then advance training (which takes sometimes over a year and a half, depends on the unit) and after training the most suitable one will go to squad leaders course. the first job the SL's get after course is training new recruits at basic training, then they continue with the same troops to advance training and then to the operational battalion/unit as their field commanders. when you reach your next rank, as a commander, you're assigned to be a sergeant and some are sent back to basic training as sergeants. there's a certain hierarchy in that... for example to become a platoon leader (an officer) and command squad leaders and a sergeant, you must be a squad leader and sergeant your self. after officer's course you are sent to basic training as a platoon leader and your will command the same troop even in battle, later on in service. so basically, there's no such thing as "drill sergeant" here. sounds like fun though.
