Ran the quad cow last night (OGP + APL + FCS) successfully twice against a mixed rebel list (Wedge, 2 Z's, Dutch). In the actual games, plus my vassal testing, one cow has been killed every time, but the herd eventually wins in all outings thus far. The list is deceptively fast, due to the large base, and the FCS makes all the difference, I think, due to the constant reliable fire.
