In this paper, we propose a new expert system for close combat in military war game model for training. Simulation logic for damage assesment is one of the main simulation functions in military war game. In Changcho 21's model which is the war game model for Republic of Korea Army corps and division, the main function of close combat's damage assessment has not been calculated by Changcho 21's model, but by COBRA which was made by US Army and has been the expert system for close combat. Results which were calculated in COBRA were sent to Changcho 21's model through a cable network. And Changcho 21's model finally calculated the value of damage assessment with the results. In this paper, we develop an new expert system for close combat using decision tree. The experimental results show that the proposed expert system has similar performance to COBRA and has less computing complexity. And it can substitute for COBRA and be applicable to battlefield.

The past combats depended often on a number of firepower and manpower. However, integrated decision support viewpoint from communications, surveillance, reconnaissance, intelligence and so forth in combats witnessed in the Gulf, the Middle East, and Afghanistan have changed the trends of combat. That is, the force multipliers which many support systems enhance the combat potential of the fighting forces significantly become big issues to win or not in that combat. According to changing recent combat trend, Lanchester's combat model is being challenged to develop keeping pace with the new trend. We approach this paper as mathematical modeling about how the effect of terrain affects in the combat. Terrain information is invisible, but it is necessary to consider for analysis of warfare. Additionally, tangible or intangible elements affecting to attrition coefficients are continuely reflected to the combat model from decision-makers, then it will be a model closer to the reality and very suggestive to the actual world.

The purpose of this study was to compare the foot plantar pressure and temperature changes of the developed combat boots with functional impact absorption and ventilation insole. A total of 11 male subjects(age: $21.8{\pm}2.2yrs$, height: $174.3{\pm}3.6cm$, weight: $71.6{\pm}8.6kg$, foot length: $261.0{\pm}1.0mm$) were recruited to compare the foot plantar pressure and temperature changes of the three types of combat boots: Combat boots A (generalized combat boots), Combat boots B (developed combat boots with ventilation function), Combat boots C (Application of ventilation function and impact absorption insole to combat boots B). Pedar-X and a portable thermistor temperature sensor were used to measure the foot plantar pressure parameters and the internal temperature of the combat boots, respectively. One-way ANOVA was used to compare the results of plantar pressure and temperature changes. The results were as follows: First, in the foot plantar pressure parameters, combat boots C showed the significant lower maximum foot plantar pressure in the right/left rear foot compared with combat boots A and average foot plantar pressure in the left foot compared with combat boots B. Second, after 40 minutes from the start of walking, the developed combat boots B and C showed the significant lower temperature than the general combat boots A.

In the past, most of battle occurred in flatland and simple military force size gave a big influence in combat result. However, after the World War I, most of battles took place at the various terrain features such as forest, downtown, jungle and many others. Therefore, terrain factor exerts big influence on battle with weapon system in the ground warfare. However, effect of terrain has been explained only by quantitative manner in the battle. Furthermore, combat simulation and modeling applied a method that lower the combat capability of battle factors. In this paper, we present instrumentation that evaluate impact of terrain using fractal dimension. We determine the fractal dimension value by the "box counting dDimension" and density to calculate impact of terrain. Furthermore, we analyzed correlation with fractal dimension and density for battle result that obtained from the EINSTein model which is an agent-based simulation. We compare with 'Stalingrad battle' result out of battle example and analyzed. This study presented a method combat effectiveness that effect of terrain calculate quantitatively using fractal dimension.

Owing to the development of science technology, particularly the smart concept and defense policy factors of the 4th industry, military weapon systems are advanced, and the scientific and operational force is reduced dramatically. The aspect of the future war is characterized by the operation of troops with reduced forces from advanced and scientific weapon systems in an operational area that has expanded more than four times compared to the present. Reflecting on these situational factors, it is necessary to improve combat methods based on the changes in the battlefield environment and advanced weapon systems. In this study, to find a more efficient future combat method in a changing war pattern, this study applied the battle experiment methodology using Vision21 war game model, which is an analytical model used by the army. Finally, this study aimed to verify the future combat method and unit structure. Therefore, the scenario composition and experiment method that reflect the change in the ground operational environment and weapon system was first composed. Subsequently, an analysis method based on the combat effectiveness was applied to verify the effective combat performance method and unit structure of future infantry units.

본 논문은 함정 전투체계의 아키텍처를 설계하고 세부 기능을 분석 및 구현하기 위한 방안 연구를 위해 작성되었다. 함정 전투체계와 같이 복잡도 높은 대규모 시스템에서 문서 산출물에 근거한 개발은 산출물 간 유기적인 연결이 어렵고 요구조건의 변화에 따른 영향 요소 식별 및 반영이 어렵다는 단점을 갖는다. 이에 대한 대안으로 제시된 모델 기반 개발 방법론을 함정 전투체계에 적용하기 위해 미 국방 분야 표준 아키텍처인 DoDAF와 이를 지원하는 UPDM, 시스템 엔지니어링과 소프트웨어 엔지니어링 분야의 모델링을 지원하는 SYSML/UML을 살펴보고 함정 전투체계에 적합한 모델 구성 및 각 개발 단계 별 모델링을 수행하는 절차에 대한 가이드라인을 제시한다.
