  ::Bf 109s were used as fighter bombers during the battle; one of the main units to use them was Lehrgeschwader 2 which (for example) lost an E-7 (Brown?) 2+ (Uffz. Klick 3./LG2) on 15 September - Battle of Britain day (Ramsay; The Battle of Britain Then and Now Vol 5 p.647.) Several other units changed role and became fighter-bomber units; eg: 9./JG26. Cheers
