The problem was that the human and computer players were both limited to 24 core and 24 support units each. So the Russians or Americans often couldn't achieve numerical superiority, and coupled with inferior AI tactics, it made it easy for the Germans. Say goodbye to those happy hunting grounds in SP2. So far, I've played the 1973 Golan Heights campaign, and it's no cakewalk. It initially seems like a cakewalk, with the superb Israeli crews getting kills repeatedly with the first shot.
Arab tanks brew up over and over again.
But oddly, more and more tanks and Sagger teams and BMPs and anti-tank guns keep popping up. At the end of the first scenario, the order of battle for both sides was displayed. Every blazing Centurion or Super-Sherman feels like you've lost a finger. And in the 1973 campaign game, Israeli armor is expensive, so lose five tanks in one scenario and you won't be able to replace them in time for the next battle. As far as I'm concerned, the jump in force size is the biggest change in the game, because it really demonstrates the quandary of a small, elite force against overwhelming numbers.
