Speaking of costs, here are the
1.03 prices of AFV's (Experience=Regular, Motivation=Normal, Fit, 0 Leadership).
GAZNZ suggested setting Rarity to 'Standard' in all games to get a more realistic force and I fully agree with him.
The cost column on the far right is rarity 'Standard', and on its left is the cost column for rarity 'None'
Note how Standard rarity triples the cost of an Abrams (APS) from 862 to 2586.
(Incidentally the costs seem to fluctuate slightly depending on whether you buy Single vehicles or whether they're part of a Formation, the purchase system is a bit complex and maths is not my strong point)
