The Chinese pilots of the Sino-Japanese War (1937-45) were the first to use American-made "all-metal" monoplane military aircraft in real combat. This includes the P-26 "Peashooter" and the Martin B-10. Information about pilots of Asian-ethnicity in combat are scant and half-assed at best. But I do know the Chinese Air Force commited the B-10 (along with fighter escort of P-26's and Hawk II/III's) in the assault of Imperial Japanese warships in Aug-Sept of 1937. The Chinese even flew an offbeat mission over Japan with a pair of B-10's bombing a few cities with leaflets(!). Like tit-for-tat, I think that Chinese B-10 mission over Japan should've been REAL bombs if you ask me. The Chinese pilots did indeed bludgeon the Imperial invaders on land, sea, and in the air with a rag-tag assortment of Curtiss Hawk biplanes, Polikarpov monoplanes/biplanes, Boeing P-26's, Gloster Gladiators, etc. Significant milestones in aviation history that are effective ignored for whatever reasons.
Oh, and for the record, nearly 200 B-10 bombers were sold to foreign customers. 120 of these went to the Netherlands East Indies. These were flown by the KNIL (Royal Netherlands Indies Army) along with the Brewster Buffalo B339 fighters against the Japanese during the early stages of the Pacific Theater operations in World War II. Martin delivered versions to several air forces. For example, six were sold to Siam in April 1937 and 20 were sold to Turkey in September 1937.
