Long Campaign

[Strono]

I just wonder how the computer chooses it's forces in the long campaign? It seems that it favors certain equpipment and some equipment is never used. For example playing as germans angainst Poland in '39, the poles are very keen on using the 75 AA gun, but i havent' seen them use normal AT guns, (i use 1200 points for equipment).
I frankly find the long campaign a little boring because if you play many battles against a nation, the computer buys a force with a very predictable force composition. Couldn't the long campaign be programmed so the computer had a couple of force compositions to choose from? It would be fun if one battle was against a tank regiment and heavy on tanks while another battle was against an infantry force with maybe just a couple of support tanks...
