Solution for missile using infantry

[ludwag]

You can also click the unit you wish to pelt and wait until they've thrown pointy sticks and then (just before they charge) cancel your order (press backspace while having the unit selected).

Then repeat this process until pointy sticks are used up.

It requires some micro-managing, but works for me.

yeah thats what i use to do. But it requires much time. Actualy this is a good reason for using pelatists.
