We can not respond asymmetric warfare effectively. The asymmetric operation is performed in asymmetric methods and means with different characteristics and functions to their enemy. And the character of the asymmetric operation have 'heterogeneity' and 'superiority' in principle. The type of asymmetric strategy is complex and diverse. Since we can classify the type of the asymmetric strategy in many different way and we must study in many ways and aspects. When we study asymmetric war previous cases from modern to ancient era, we can find that the key factors of the victory have superiority of the asymmetric strategy and discriminatory measures. The asymmetry is created when one party has to adapt to the strategic environment. If we want to secure a strategic advantage, we must take a number of case studies and countermeasures for asymmetric warfare.

Modern Warfare is transforming into a Network Centric Warfare(NCW) where surveillance systems, command control systems and strike systems are interconnected with advanced IT technologies to share battlefield situations. The South Korean military is using the various tactical data links(TDL) such as Link-K, Link-16, Link-11 and KVMF depending on each military's battlefield situation. Joint Tactical Data Link System(JTDLS) is a system thar shares tactical information in near-real time between army/navy/air joint forces and additionally establishes Link-22 in Link-K, Link-16 and KVMF. In this paper, we propose the Link-22 system structure, Link-22 message analysis and the interface structure between the tactical data link processor and Link-22 to apply Link-22 to the JTDLS.

The need to acquire a multi-mission modular ship to carry out the mosaic warfare of modern warfare is increasing. In such a modular ship, not only domestic R&D equipment/systems but also an manned/unmanned complex system purchased overseas must be mounted together. In order to successfully design/construction a multi-mission modular prototype battle ship and turn it into timely power, it is necessary to apply a new technology so that it can be installed flexibly in a limited space and time. However, the existing welding installation method not only limits flexibility in design/construction due to safety problems, but also has an inherent problem that the cost and time required to correct defects and supplements are excessive. Therefore, this study introduces the current status of next-generation installation devices developed/applied in the advanced navy and the field demonstration results applied to battle ships to provide flexibility in this respect.

The aspect of modern warfare is gradually changing to a network of warfare, and its central information electronic warfare is evolving every day. Recently, domestic equipment of electronic warfare, which have succeeded in domestic localization, are strongly influenced by the nature of the environment. Therefore, the structural reliability of the antenna switching module that connects the mast and antenna of the ES equipment is the most important. This study proposed a structure that has an improved structure of antenna switching module by currently analyzing the structure of the antenna switching module and the environmental influence. By modifying the structure of the antenna switching module welding method and part of the reinforcement block, the structure was improved and the validity of the improved antenna switching module was simulated using a load test. The simulation showed that the safety factors of antenna switching module welding point and reinforced block part was enhanced 5.3 and 1.5 times compared to the existing values. These values were verified by load (181kg) test results, which was each 3.7Mpa and 64.4Mpa. The load test results were similar to the simulation results and load supporting capacity of the proposed antenna switching module was enhanced.

The general aspects for the future warfare shows that the concept of firepower and maneuver centric warfare has been replacing with that of information and knowledge centric warfare. Thus, some developed countries are now trying to establish the information systems to perform intelligent warfare and innovate defense operations. The C4I(Command, Control, Communication, Computers and Intelligence for the Warrior) systems make it possible to do modern and systematic war operations. The basic idea of this study is to investigate how TAM(Technology Acceptance Model) can explain the acceptance behavior in military organizations. Because TAM is inadequate in explaining the acceptance processes forcomplex technologies and strict organizations, a revised research model based upon TAM was developed in order to assess the usage of the C4I system. The purpose of this study is to investigate factors affecting the usage of C4I in the Korean Army. The research model, based upon TAM, was extended through a belief construct such as self-efficacy as one of mediating variables. The self-efficacy has been used as a mediating variable for technology acceptance, and the variable was included in the research model. The external variables were selected on the basis of previous research. The external variables can be classified into following: 1) technological, 2) organizational, and 3) environmental factors on the basis of TOE(Technology-Organization-Environment) framework. The technological factor includes the information quality and the task-technology fitness. The organizational factor includes the influence of senior colleagues. The environmental factor includes the education/train data. The external variables are considered very important for explaining the behavior patterns of information technology or systems. A structured questionnaire was developed and administrated to those who were using the C4I system. Total 329 data were used for statistical data analyses. A confirmatory factor analysis and structured equation model were used as main statistical methods. Model fitness Indexes for measurement and structured models were verified before all 18 hypotheses were tested. This study shows that the perceived usefulness and the self-efficacy played their roles more than the perceived ease of use did in TAM. In military organizations, the perceived usefulness showed its mediating effects between external variables and dependent variable, but the perceived ease of use did not. These results imply that the perceived usefulness can explain the acceptance processes better than the perceived ease of use in the army. The self-efficacy was also used as one of the three mediating variables, and showed its mediating effects in explaining the acceptance processes. Such results also show that the self-efficacy can be selected as one possible belief construct in TAM. The perceived usefulness was influenced by such factors as senior colleagues, the information quality, and the task-technology fitness. The self-efficacy was affected by education/train and task-technology fitness. The actual usage of C4I was influenced not by the perceived ease of use but by the perceived usefulness and selfefficacy. This study suggests the followings: (1) An extended TAM can be applied to such strict organizations as the army; (2) Three mediation variables are included in the research model and tested at real situations; and (3) Several other implications are discussed.

As a result of the Falkland Islands War from April 2 to June 14, 1982, Britain overcame severe economic depression and reclaimed the glory of the former British Empire by winning the war. On the other hand, Argentina was greatly affected by the collapse of a military dictatorship and the birth of a democratic government. This study suggests strategies for responding to maritime disputes that may occur in Dokdo Island in the future by applying "DIME on PMESII" to the Falkland Islands dispute. In particular, the study analyzes how DIME (diplomacy, information, military, and economy) capabilities have an effect as a means of the total national power of a country that effectively controls the disputed territory. Based on the results of this study, the response strategies related to the Dokdo maritime dispute are as follows. First, effective control over the disputed territory should be effectively maintained and strengthened like in Britain. This strategy inspires patriotism, supports the government during warfare, secures a just cause for war, and gains international support. Second, 'DIME on PMESII' was effective in modern warfare by focusing our DIME capabilities on the weaknesses of the other country's PMESII system. That is, wars are not won simply by the conflict of armed forces but by a nation's overall national strength, such as diplomatic, information, and economic capabilities. Third, appropriate strategies for neighboring countries are needed to overcome the possibility of limited warfare in the sea through preparations for Dokdo maritime disputes in the future.

This paper examines the history of karate, its utilization as military training, and its value as a national defense sport. Originating from Okinawa, karate was introduced into Japanese military training in the modern era and spread worldwide. During World War II, the Japanese military intensified karate training for close-quarters combat. Post-war, karate was introduced to Western society through the U.S. military presence in Japan. In contemporary militaries, various martial arts, including karate, are utilized in training programs such as the U.S. Marine Corps Martial Arts Program (MCMAP) and the Israeli military's Krav Maga. These programs integrate techniques from karate, judo, boxing, and other martial arts to create systems optimized for real combat. In military education, karate enhances individual physical and mental capabilities and improves unit combat effectiveness. Rigorous training develops physical fitness, mental resilience, and practical skills for close-quarters combat. Group training fosters camaraderie and unit cohesion. However, due to the changing nature of modern warfare, it is necessary to reconsider the proportion and methods of martial arts training in military education. With the advancement of high-tech weaponry, team operations have become more critical than individual combat skills. Rather than applying traditional karate techniques unchanged, it is essential to modify and develop them to suit modern warfare. Nevertheless, the value of martial arts training, including karate, remains significant in cultivating key soldier qualities such as physical strength, indomitable spirit, and camaraderie. It is anticipated that militaries worldwide will continue to evolve their martial arts training systems in line with changing times.

Currently, drones are used in various fields such as transportation, agriculture and military. Especially, drones for military use are developed and utilized in many ways such as reconnaissance and bombing to minimize one's own damages. Nevertheless, they are developed as new weapons of modern types, so it is difficult to use them together with existing weapons. In this study, a drone program for effective bombing of mortar, which is often used in modern warfare, is developed. In mortar, a forward soldier comprehends the location of enemy for its distance and altitude, input them in data computer of launching angle, and applies the result value to cannon to launch. However, the existing method has low accuracy of bombing because observing shall be done within 1km from the target, and measuring accurate direction and velocity of the wind is difficult. Whereas, in the program of this study, the location of target, GPS, direction and velocity of the wind, and altitude are measured through drone. Each digit is used to calculate bombing specification for optimal bombing through the calculating formula of launching angle. In addition, when specifications are input in the program, the calculation is done automatically, so that it can be used in various mortars and shells. With the use of the program in this study, the location of enemy can be comprehended, and bombing specifications can be calculated quickly. It also enables the intensity of the wind to be applied for accurate bombing.

As NCW has appeared, the importance of interoperability in modern warfare has been also increased. Korean Defense has constructed and used the Systems Interoperability Test & Evaluation System based on LISI, in order to increase interoperability between Defense Information Systems. However, its evaluating targets are limited to only the information systems, so that it is difficult to apply it to weapon systems. This paper proposes an integrated interoperability assessment framework for korean embedded software of weapon systems based on reviewing the limitations of SITES and the other interoperability assessment models.
