There is. Under the Units tab put in "C3" under the Alpha Strike abilities tab.Here is a link to exactly that search, and you can further narrow it down by type, faction, era, etc.Edit: Of course the link I gave shows ALL C3. If you just want C3 Slaves, search for C3S. If you just want boosted C3 slaves, search for C3BS.
C3S = C3 slaveC3M = C3 masterC3BSS = C3 Boosted slaveC3BSM = C3 Boosted MasterC3M2 = dual masterC3BSM3 = dual boosted masterC3EM = C3 Emergency Master

Wonder if it is the AC3 that is throwing it off.
Considering that it's got twin AC/20's, can someone explain why it's got the AC3/3/- special? Shouldn't it be AC4/4/-?
