This articles is aimed to examine Combined Tactics of Military Carts, Cavalry and Infantry originated from Yang Wan, the high rank General of Late 18th Century. Tactics using Military Carts introduced from Ming China were not generally spreaded in Joseon Forces because of Joseon's topographical characteristics with rugged mountain roads. As manufacturing technology further developed, Military Carts with numerous wheels were devised, and various cannons were loaded unto them to attack enemy cavalry. In addition, Military Carts with a single wheel were invented, which could be moved along even a narrow path in 18th Century. Entering the Middle 18th Century, Qing China fall into crisis at home and abroad and potentialities of the outbreak of war with Qing China and Joseon became higher. Taking advantage of the changing circumstances, Joseon's learned men insisted on occupying Liaodong(遼東) of southern Manchuria. Under these circumstances, the Joseon had to prepare itself for the possibility that the country might be engaging Qing China in a full scale war in southern Manchuria. As a consequence, Military Carts were manufactured and Combined Tactics using the cavalry, infantry, and Military Carts in concert developed such as the ‘Sangseungjin(常勝陣)’ by Song Gyu-bin(宋奎斌) and ‘Nok-gak Geojin(鹿角車陣)’ by Yang Wan. Yang Wan originated so-called ‘Nok-gak Geojin’ and its military organizations, training procedures, and battle practices in Akkidoseol based on his studying Six Flowers Formation(六花陣) of Liweikungwendui(李衛公問對). ‘Nok-gak Geojin’ by Yang Wan shows that Joseon's military science in Late 18th Century had a higher level.
