Because casualties are expected to be quite high each player directs up to four characters. The scenarios, provided the GM lasts beyond the first one, are linked to each other and form a campaign.
Player characters gain experience and retain equipment gained.
Likewise, units led by the player characters retain losses in men and materiel suffered to the next scenario unless resupplied. The game is free with all the usual advantages and disadvantages. The GM attempts to maintain a turnaround time of one week, but no guarantees are given. Due to limited resources not everyone gets to play, though would-be players will be added to a list of candidates. The GM may exclude any players from the game or even drop the whole project at any time without prior announcement or even a good explanation.
