Milestones

Milestones increase the production of units in Boot Camp when they are reached, or reduce the time needed to produce power points (in the early game).

Milestones are strictly per-unit. There is not a "bonus to all units" for getting all units to a certain amount.

Most milestones give a x2 multiplier, but some of them give larger multipliers.

Milestones are usually every 100 units, but late in the game, the gaps become bigger. (250, then 500, and eventually 1,499.)
