This Squad Ops is not “tempests against A8s?”. That is a rather limited view would you not agree? There has never been a TOD (Squad Operations) that just pits one plane against another, and their never will be. So all things equal it is:
P51D, P47D25, P38L, Spit XIV, Tempest V, Mosquito VI, B26
VS Fw190A8, Fw190F8, Me109G10, Me262.
Time is Aug 1944 and the chart I used is below and the actual write up is here.
