That's a page that discusses a number of games the military uses for training, including: CCM.
It also says: " Future version will have the ability to play in a campaign mode, or incorporate 4 players."
It's the download of the 2 MB., 76 Page: "Workbook 1-CloseCombatMarines.doc." And, especially interesting is Part 2, that has a thorough discussion of what looks like all the scenarios in the game. I haven't gotten mine yet(I ordered it today & should be here in a few days)but, it looks that way anyway.
Now, maybe that same .doc file actually installs when the game installs. But, even if it does, it's interesting reading, especially for anyone who can't get the game.
Sorry that first link is so long, but, I copied it exactly from the address bar when I got to the website itself. So, that's how the link is.
