A feature of the 1st Clone War were the mass attacks by suicide planes like the A-22 but this kind of offensive weapon fell out of favour once HCS technology had advanced to the stage where they could compete on a level playing field with DDS air weapons (and now have surpassed the DDS easily). While the 1000s of suicide aircraft were withdrawn (several hundred A-22s became O-43 general purpose "hacks" though these are being phased out now) a number of squadrons remained. In the event of a war the pilots would be given aircraft from storage such as older A-85s and O-43s to resume the suicide attack role.
Over time these squadrons have been disbanded and this week the final 2 squadrons have been stood down thus ending a peculiar chapter in the history of the HCS.
