[Mobhack]

The Ai buys leg infantry with its spare change points as they are cheap, unlike modern AFV. The AI buys extra leg infantry in city fights. It only buys mech infantry and tanks when it has the points to buy the things.

Setting the AI tank heavy flag might also help - then it wil prioritise tanks companies when it has the points to pay for them, but it will still round off with cheap units (leg infantry, if-AT dets etc) when points remaining are low.

Of course, you could always hack the OOB you are playing against and say replace the standard leg platoon with an MBT platoon, and hack the eifle coys as well to point to a new leg platoon. Or just add 1-2 MBT to the standard rifle platoon. That would soon soak up the AIs spare points.
