You may wish to have a look a series of PC Games by Microsoft I played around ten years ago. They were called Close Combat. Althought they were not played in the same dimension as your game. They certainly had all the detail and infomation you may be looking for.
There was a D-Day game, Russian Front and my Favourite one....Arnhem, I actually managed to capture and hold all 3 bridges for 30th Corps.
Have a look see at them ..... They detail all different units, ability and equipment etc. including Armour and artillery pieces.
Good luck with it
