The "Silver Helmets" group of tournaments, which was launched today, should be of special interest to SoC grads (and non-grads too). Every game is 6-player escalating, the same class of games the SoC teaches. Most are either Standard or Terminator. About 60% of the games are sunny, and all are non-trench.
To see more detail or to join a Silver Helmets tournament, just click on the Silver Helmets link inside the Great War box at the top of your My Games page. The entry cost is 3 tokens. If you're not sure how to get tokens, check the tokens page of the main Great War discussion thread.
Silver Helmets will be available until November 2nd. When it's gone, it's gone.
