I dont think that turret steer should be available on snubs anyway. guns/turrets on it not designed to fight like that. in GBs and more each gun controlled by AI or Human, so it cant shoot any target. but snub can fight only with one opponent at time.
because as Swallow sayed: ''I easilly killed LF in Bomber''. and this is not that should happen, yes? at least with using TS
