The tactics of the second conflict reflect the way the RFC/RAF - Offensive - and the Imperial Air Service - Defensive ended WW1. In Spain the Germans replayed 1918 and won. It was not until the bombers went deep into Europe that the Germans used 'air defence'. Even then the tactics were still defensive until late in the war.
