The T2 mobile flak artillery for the factions are the respective UEF Sky boxer, Cybran Banger, Aeon Ascendant, and the Seraphim Iashovah. Flak artillery are anti-air weapons with high DPS and a large area of effect, dealing significant damage to clusters of air units, especially the slow gunships. The mobile versions of the flak artillery have less HP than T2 anti-air flak artillery but cost much less, and have almost exactly equal DPS.
