South Korea suggest that the United States government should delay the date to hand over wartime operational control (OPCON). It is fixed on December 1, 2015. Typically the president's position as head of the executive authority is coming from the Commander-in-Chief of the Armed Forces. Now we should know the commander-in-chief of the nation's forces and the meaning of OPCON. The relationship between sovereignty and the commander-in-chief of the nation's forces is a little different. This is one of the efforts to enlarge the efficiency of Armed Forces. Of course, operational control is little control of the sovereign personnel, logistics, administration, discipline, organizing, training, etc. It does not control all matters. The current ROK Combined Forces Command itself is made with reference to the North Atlantic Treaty Organization(NATO). If we insist our own sovereignty is infringed because of OPCON, that claim is coated in irreparable damage to the national interest.

The Korean peninsular is a typical mountainous terrain country which has 75% of mountains with having featuring of east-high west-low and north-high south-low type. Though the physiographic feature is not changed, the future operational environment has been frequently changed through artificial transformation by people living in the city. While Korea has been changed continuously since 2000, 90% of Korean territory has been urbanized and the majority of people live in the city. In particular, in the case of combat in urban area, there might be lots of limitations because of confusing with millions of people and complex buildings. The combat commanders should make an effort to overcome such difficulties through detailed IPB(Intelligence preparation in the battlefield) considering various situation before planning for major operations. They should change warfighting concept and paradigm. This paper finds the normal characteristics of urban operation and physical traits of the Korean peninsular. As the urbanization has been accelerating in Korea, practical implications about how to prepare the urban operation are discussed.

미래의 전자전 체계들은 성능과 작전가용도가 증가되도록 요구될 것이며, 더욱 복잡해져 가고 있는 위협환경에 대응할수 있는 전자전 체계라야 할 것이다. 그러기 위해서는 유효복사 출력(ERP)을 높이고, ECM 에너지의 질을 더욱 개선하며, 방사에너지의 제어를 한층 잘해야 할 것이다. 이와함께 아주 높은 수준의 작전 가용도가 요구될 것인데, 이는 새로 개발되는 항공기들의 매우 높은 출격율을 유지하기 위한 것이다. 지원비용을 막대히 증가시키지 않고 이런 고도 수준의 가용도를 달성하려면 역시 신뢰성과 정비유지성을 상당히 개선해야만 한다

K9 BTCS의 성공적인 개발은 디지털화된 사격지휘 전산장비체계로 종심지원작전, 근접지원작전 그리고 대화력전을 수행하는 여건을 제공하였다. 또한 K9 자주포의 전술적운용 능력과 실시간 타격전력 발휘에 질적인 발전과 변화를 가져다 주었으며, 기존의 BTCS를 기반으로 하여 화력지원 사격지휘체계를 한 단계 높은 화력을 운용하도록 성능개량한 것으로, 무선에 의한 디지털 다중임무수행, 표적획득체계와의 연동운용, 상황도시 등을 윈도우 환경에서 운용할 수 있게 되었다. 이로써 $C^4I$체계상에서 SHOOT & SCOOT 전술적 운용과 효과중심의 탄약을 적시에 사용할 수 있게 하였고, 화력집중과 분산을 용이하게 하였다.

In the future combat fields, US department of defense (DoD) pursuits the enhancement of the synergy effects of the force through the networking. In specially, the US army force has been emphasized the information superiority for the knowledge superiority and decision superiority of the collaboration force in the Joint Vision 2020, when the operations is performed in the battle fields. In this case study, we are reviewed about the concept of network centric operation and operation case in the centering around the US and analyzed the quantitative distance and effect, performance of communication relay about the distance of mission operation.

To prepare for the network centric warfare, Korea Joint Tactical Data Link System(KJTDLS) has been developed by the South Korean military recently and its development is divided into two phases: basic and complete ones. Due to the limited bandwidth and low transmission efficiency of the developing KJTDLS (basic), lots of problems could be occurred when the TDMA protocol in Link-16 is applied. In this paper, a new dynamic TDMA frame structure for KJTDLS(basic) is proposed and the performance of the proposed is evaluated through the implementation of simulation.

Recently, Population has been concentrated in cities due to rapid economic growth. As a result, urban buildings are becoming more dense, high-rise, and diversified. The shape of these urban buildings increases the risk of fire, accidents and crime. The narrow living space has the characteristic of the unchanged floor. In case of a fire, the living space of the narrow residence is large in the damage because the smoke diffusion rate is fast. The radio wave transmittance and transmission distance of wireless communication used in fire fighting operations vary depending on the type of building materials and buildings. Therefore, this paper analyzes the building materials and structural characteristics of the narrow residential space for efficient fire fighting operations. We have developed a communication environment solution for a narrow residential space for the optimal fire fighting operation through the measurement of the radio wave transmittance and the transmission distance of the wireless communication.

Since cyber operations are performed in a virtual cyber battlefield, the measurement indicators that can evaluate and visualize the current state of the cyber environment in a consistent form are required for the commander to effectively support the decision-making of cyber operations. In this paper, we propose a method to define various evaluation indicators that can be collected on the cyber battlefield, normalized them, and evaluate the cyber status in a consistent form. The proposed cyber battlefield status element consists of cyber asset-related indicators, target network-related indicators, and cyber threat-related indicators. Each indicator has 6 sub-indicators and can be used by assigning weights according to the commander's interests. The overall status of the cyber battlefield can be easily recognized because the measured indicators are visualized in time series on a single screen. Therefore, the proposed method can be used for the situational awareness required to effectively conduct cyber warfare.

The boundaries of ROK maritime jurisdictional area remains unclear as two Koreas failed to draw clear maritime boundaries at the armistice agreement and there are no clear maritime boundaries with China and Japan. After the Korean War, the United Nations Command established the northern limit line(NLL) as well as the area of operations(AO) to enforce the DPRK's compliance with the armistice agreement and has been controlling all of the maritime and air activities in the region. ROK also has been controlling the passage of DPRK vessels in the area. Within the AO, third nation vessels have freedom of navigation, Yet, due to the division followed by the Korean War, ROK classifies DPRK as a hostile state and unique controling system is applied to DPRK vessels. Since the establishment of the AO, many changes have been occurring such as adoption of the UN Convention on the Law of the Sea(UNCLOS) and two Koreas' joining the UN. Also, there are continuous inter-Korean conflicts. Therefore, the geographical span of the AO needs to be reconsidered. Furthermore, a legal measure which ensures ROKN vessel's functional capability of controling DPRK vessels must be introduced. This thesis examines post-Korean War DPRK vessel control system in the Korean peninsula as well as how it should be improved.

Required Operational Capability(ROC), which means the performance of a weapon system, is determined when estimating the requirements of a new weapon system. It is very important to define the ROC as it has a decisive influence from acquisition of a weapon system to tactical operation. In this study, we propose a simulation methodology to verify the ROC of the Para-Observation Munition(POM), a newly developed weapon system. To this end, we propose a discrete-event simulation model that takes main performance of the weapon system constituting the ROC and environmental factors that affect performance of the weapon system as input values, and outputs operational effect as a result value. It describes various simulation logic required to implement a simulation model, and explains how to verify ROC using various simulation results such as sensitivity analysis. POM is a weapon system that does not have a similar one and that is difficult to directly utilize the military analysis model. This study can be used as a methodology to analyze the ROC and predict operational effects of weapon systems such as POM.
