Your first turn will be sent to you on the next working day as an HTML attachment and should be saved to its own folder (e.g. C:\Troopers). This will contain the necessary information to begin playing, such as your squad statistics and a map containing information about the surrounding region. See sample turn

You will need to download the graphics from this link, and save the graphics in the same folder as your turns.

And why not try reading the rules before you send in your first turn.
