A lot depends on the exact perspective you take and which tradition you choose to look at. According to Evola, Buddhism is animated by a strong warrior spirit and conceives of spiritual growth as a battle to be waged. If we are looking at the physical, military aspects, though, the most favourable comparisons with European paganism would involve Zen and other forms of late East Asian Buddhism, since those forms were very popular with the Samurai and even the Imperial Japanese Army that came afterwards.
