I put together some platoon sheets for Chain of Command a few months ago when I was introducing one of the members at the club to the game. Idea inspired by the Tactical Painter's sheets, with a few extra bits of information I thought would help make the game a bit easier for a new player.
The downloads are below, let me know if these have been any use, and I'll update as I go with sheets for the different armies.
