targeting seekers??

[Suicide Junkie]

Autofiring weapons such as stock PD will shoot as soon as a legitimate missile or unit comes into range.

In order to change this, you need to make them not PD guns, but instead regular guns that can target fighters/missiles/etc.

Thanks for the clarification. So, a really effective strategy would seem to be to fill the skies with fighters to act as flak, and then have some seekers in the mix to do the real damage.
