Hi Paul, yes, the kids in the photos are the players. (Some are better than some of the adults I might add!). Some of my photos have the game's story posted with them. You can see the game sessions on Boardgamegeek.com if you look at The Games of War. Look undergames played and you can read the stories to get an idea how the various games work. I hope that helps!
The figures aren't made any more but they do make 6mm inidividual figures mounted on stands. The rules are from my book, The Games of War: A Treasury of Rules for Battle with Toy Soldiers, Ships, and Planes. My book has 39 sets of rules and the one I used for this battle was La Gloire de Guerre on pages 78-81. While written for individual HO and 54mm figures, I used one stand as one figure (1 battalion). 6 figures make the average brigade.
