Considering the changes of Security environment such as the change of re cent war trend, modern warfare and ROK-Military Reform etc, these days a re debating for the developing of ROK-Milirarys strategy. The core of Requ irements according to following like these ; Firstly, Korea must establishes on the military strategy with playing a leading role, considering the changes of recent war tendency and ROK-Military Reform(reducing the scale of milit ary, reforming a technique forces), and the wartime OPCON Transition. Secondly, The new strategy must be made considering that a deceive war has purposes and objectives, How long the executing period is. where a dec eive war takes place, What is the way(means and ways=Art of war), What are the available assets for the deceive war. And according to the Art of war on the base of these military strategy must be developed and ROK Military m ust be trained. But Investigating the our statues, there are a lot of problems on linking with Military strategic concepts - Doctrines - Construction of Mil itary power - Education & Training. The ways of New ROK-Military Strategy insisting on this study have to i nclude the components( those are Purposes and Objectives, Means and Ways (Art of war), operating Military assets) of planning Military Strategy reflecting the Korean peninsula special environment and the changes of recent war tre nd. and I described as ; Firstly, Establishing new strategic purpose and obje ctive are similar the former one. the different focus is that this study is addi ng Defence of the border with other nations on the former concepts, such as the Occupation on north Korean area & Reunification and removing the nort h korean government. Campaign on the concepts of this study will be separa ted with several one, not one campaign. and Each campaign must define each purpose & objectives. Secondly, On the level of Art of war, When we consider the tendency of recent war, modern warfare, Available military assets, Reform of ROK-Milit ary, Environment of time and space, etc, this study insists that the campaign of Korean peninsula have to change several campaigns, improving that now Korean peninsula be defined as one campaign and separated with Main opera tions in the one. there are some reasons that After turning over the wartime OPCON, Korean military must carry out some decisive operations as a statu s of main operator with the wartime OPCON on the war, so have to fight wit h substantial available military assets. and the Art of war must be made con sidering those. For that reason, this study suggested that It is desirable that the campaign for Defense when north korea attack to the south korea have to be divided over 2 campaigns, and the campaign for seizing north-korea ar ea and reunification when we counter attack to the north-korea. have to be divided over 3 campaigns. On the focus of Military assets, The way of head for building new Military strategy have to meet next two demands ; First, Military assets have to be constructed on the bases of the Art of War of each campaigns. Because Art of war is quite different with Time and Space, and at this time Military asset s to be operated are different. Thus, The military assets operated at Now co ntacting area with enemy(the area of DMZ and FEBA), Deep area of north k orea, and The border with other nations have to be fixed and constructed ac cording to each Art of war concepts. Second, Our neighboring countries are Strong nations that can be heading for world hegemony. Our nation which is small nation can not build all of the military power requested for winning aga inst Our neighboring countries. Thus, we have to fix the appropriate constru ctive goal of the military power. and Those are linked with nation policy, nat ion strategy, military strategy. For overcoming the shortage of military asset s, those have to be reflected on the building plans of military power conside ring those possibility, and those can be arranged at the level of national stra tegy. At this time, we have to develop the plan that the shortage of military power make up with ally-nation``s military powers.
