with phalanx: Iaosatae shoot 9/15/15/10 phalangitai
without phalanx: Iaosatae shoot 32/31/31/27 phalangitai

At least as much of a difference. Which is consistent with increased shield values, since Iaosatae have more ammo but less attack, and their ap ability doesn't make a difference against shields.
Where's your control of other missile units?
