In it are references to a bunch of FMs that will also help. Most of these FMs are also provided on the CD that ships with AATF.
You should get exactly the same ATF experience playing the game in AATF, only better. It will include all of the GUI improvements over ATF, as well as the new damage model, improved AI, and other enhancements. The tactics for ATF scenarios remain the same whether you are playing the scenarios in ATF or AATF. Sound, combined arms, mechanize warfare tactics are the key to winning ATF scenarios.
