High Quality Content by WIKIPEDIA articles! The Type 14 10 cm AA Gun (????10cm???, Jy?yonen-shiki jissenchi Koshah??) was an anti-aircraft gun used by the Imperial Japanese Army after World War I. Only a small number were produced, and it was superseded by the Type 88 75 mm AA Gun in production before the start of World War II. Due to combat experience at the Battle of Tsingtao against the German Luftstreitkrafte?s fledgling squadron of combat aircraft, planners on the Imperial Japanese Army General Staff quickly realized that this new technology posed a threat which required countermeasures. This evaluation was further reinforced by reports from military observers on the European front in World War I.
