I’ve added an optional rule for Inflexible units. They get one less activation unless every unit is within 6″ of each other. You can fiddle with the distance.
My gut feeling is to stick with 1 per 3.
Give the NATO boys +1 (for the top tier)
Second tier NATO no changes unless fighting category 3 WARPAC
WARPAC normal activations but Inflexible.
WARPAC allies have 2 Despair points outside their own borders.
