[Mobhack]

This is it - tanks in the later years are hugely expensive, when APCs get festooned with missiles and thermal sights they cost almost as much as the MBT, and AAA assets (and attack helos etc) also get hugely expensive as well. Cheap bazookas get replaced by ATGM teams with expensive missiles and expensive thermal sights. As in real life, military stuff has skyrocketed in cost over the post war period.

AI tank heavy means that it will try to buy tank coys if it has the points available where it would have bought a platoon, and occasionally it will double buy the tank formation if it has points remaining. But those points will soon run out as the buy goes on and AA assets etc are also bought. When it is lacking in points, it fills out with the cheap stuff.

Therefore the AI will need more points, as time goes by in order to show up with a lot of tanks. 50 point Shermans in 46 become 500+ point MBT by the 2000s. 15 point half-tracks become 350 point IFV.

Of course - if you really want the AI to buy 30 or so MBT and nowt else, you could always do a little editing of the OOB in Mobhack to get one you like to play against. Move the infantry companies somewhere else, and replace with MBT formations, etc.
