I ran a small Oct 8 1973 (Israeli counterattack on the Southern Front)
style scenario. I gave the red/blue/Israelis T62M and the Red/Red Egyptians
T62(1972) and pretty bad motivation and training for both sides (since the fighting along the Suez was very far from what either side had trained for)...things may have been a bit unrealistic, but the unit behavior in the game was quite plausible with the Israelis doing a lot of reversing the the Egyptians "milling around"...Not a bad game experience.
An official module that covered say the Yom Kippur War could be pretty good.
And if Shock Force can cover WWII and modern stuff it ought to extend pretty easily to cover 1967 and 1973.
