This classic Chinese strategy is known as " bae - soo - jin " ( in Korean ) . Although fighting on a flat plain seemed a reasonable strategy , the various vegetation that grew there at the time actually hindered mounted troop movements . Another factor that might have impeded the Korean cavalry would be their weapons . Their main weapon was the Korean composite bow . Considering that the Japanese employed a considerable number of pikemen , combined with the unfavourable terrain , the Korean cavalry might have had great difficulty charging the Japanese .
