I started programming by editing the source of an entire Multiplayer gaming engine with far more code than the stock scripts, I think I can handle it. ;D
Edit: it looks like I can accomplish it by just making a copy of the "Scene_Battle" script then use conditional statements based on the turn number to block or allow input from the commands. Then use that in just the instance of the tutorial. If this works it will have been child's play and I have never messed with RGSS before XD
Edit #2: I did it! All I had to do was copy the battle scene and add conditions to check certain variable I set based on what prompt I had for when they wanted to enter a command if it didn't match up it would reinitialize the command selection window. then I made it only use that scene if the Troop ID matched the Tutorial troop. Aside from I minor bug where the Battle Music doesn't play and it play's the map music this is PERFECT! The music can be fixed with a few event Map music changes before and after the custom scene.
Edit #3: Fixed the sound bug
