Try my Operation Sunlight mission on the ATAG server or on the AUS_Nations@war server. It has random vehicles, trains etc. Random number of Ai planes in Ai flights. Airbase comanders monitor enemy activity over their airfields & will order-in more AA defences if they are frequently attacked. Hell, even the airfields will randomly upgrade their aircraft from time to time ie. An airfield with only a Bf109E-1 when you start the battle will suddendly get upgraded to having both Bf109E-1 & Bf109E-3's, hurricane Rotols upgraded to hurricane 100octane etc.
