I'll grant there was a revolution in the development of tactics (and parts of war fighting in general), obviously I'm not claiming that wars don't lead to great changes to the practice of war, merely that "technology" is a much greater enterprise in society the particular part concerned with war. Further, the development of tank models was pretty clearly a case of (rapid) evolution rather than evolution. For example successive models of Panzer and Panther tanks used the same engine model: reuse of such a central system is a clear sign of evolutionary modification rather than revolutionary innovation.
