Sokojakdaedo by Yi Kang-nyeon, the leader of Hojwauijin in the end of Choseon dynasty, is considered a material to show the organization and tactics of the righteous army since it has the military organization, its march, methods of warfare, and leader's virtues. It is, however, the extract of a traditional strategy book and almost the same as Byeonghakjinam written in the 17th century. The information in Sokojakdaedo, therefore, is kind of common knowledge to the traditional soldiers.
So, it is not appropriate to understand the organization and tactics of the righteous army in the end of Choseon dynasty through this material. The righteous army was guerrilla forces going for warfare against a better-equipped Japanese enemy only with all sorts of outdated weapons. Its reality is not reflected on Sokojakdaedo. The unit organization of the two had the same name but was very different with each other in size.
Although Sokojakdaedo is not Yi Kang-nyeon's creative piece, its basic principles of command and control might be used in the righteous army activities. As civilians become soldiers by doing close-order drills at first, so could Yi Kangnyeon become a respectable righteous army leader by embodying in himself the virtues of commanders emphasized in the traditional military strategy.
