보병화기의 전투효율성 향상을 위해 세계 각국은 소총에서 구경축소, 경량화, 체계화 등 꾸준한 개량발전을 시도하여 왔으나 실제 전투상황하에서의 명중률 증대측면에서는 결정적인 개선을 가져오지 못했다고 평가하고, 소총의 기본 설계개념과 세계 각국의 차기소총 개발현황 및 발전추세에 대하여 개괄적으로 고찰해 보았다. 따라서 이와 함께 현용 K-1A 기관단총, K-2 소총의 Life Cycle(20-30년)을 고려할 때 2000년대 초에는 차기소총의 대체 필요성을 제시하고자 한다.

최근 산업체, 공공기관 등 거의 모든 분야에서 인터넷 기술을 이용한 클라이언트/서버환경으로 시스템을 구축하고 있다. 본 논문에서는 이러한 환경에서 DIS와 ADS의 개념을 이용한 전투 시뮬레이션을 수행하여 기존 모델의 비현실적인 가정과 문제의 난이도로 인한 여러 제약을 해결할 수 있으며 시간 및 시스템의 활용면에서 효율의 증가에 대한 모델을 구현하였다. 본 전투 시뮬레이션 모델은 인터넷 프로토콜의 표준으로 자리하고 있는 TCP/IP를 이용한 것이기 때문에 이동통신을 이용한 무선 데이터는 물론, 인터넷 접속이 가능한 곳이라면 어떠한 환경에서도 수행이 가능하다. 노드에서 시뮬레이션이 종료되면 여기서 발생한 생존 대수, 발사시간 분포 등의 정보는 서버에서 적절한 의사결정을 수행한 후 다른 노드로 전달하게 된다.

Most combat simulation models, including Korean Army's combat models for simulation analysis, have too much limitations to be used for analysis of complex combats like joint combat fires. We analyze requirements for modeling and simulation of Fire-Eagle, which is a joint combat fire model of ground combat fires and army aviation. We then propose a simulation model for Fire Eagle and derive operational strategies for improving the joint combat fire. To do these, we analyze effectiveness of specific operational plans and scenarios by using the simulation model. We demonstrate ways of developing efficient and effective operational plans from the simulation experimental results.

Naval combat systems use real-time processing and compositing of collected information to provide the optimal combat capabilities that maximize survival and ensure mission effectiveness. The software for a combat system has dozens to thousands of components depending on the size of the system, and the communication between the components is achieved via DDS. Although the message interface of the combat system is managed through MDMS, an increase in the system size can result in problems such as the deterioration of the development efficiency. In this paper, we implement XMDMS to operate a distributed processing environment and then solve the problem of the reduction in the development efficiency caused by a load at the server. The experimental results shows that XMDMS improves the processing delay and network performance compared to MDMS.

Naval CMS(Combat Management System) is linked to various sensors and weapon equipment and use DDS(Data Distribution Service) for efficient data communication between ICU(Interface Control Unit) Node and IPN(Information Processing Node). In order to use DDS, software in the system communicates in an PUB/SUB(Publication/Subscribe) based on DDS topic. If the DDS messages structure in this PUB/SUB method does not match, problems such as incorrect command processing and wrong information delivery occur in sending and receiving application software. To improve this, this paper proposes a DDS message structure integrity verification method. To improve this, this paper proposes a DDS message structure integrity verification method using a hash tree. To verify the applicability of the proposed method to Naval CMS, the message integrity verification rate of the proposed method was measured, and the integrity verification method was applied to CMS and the initialization time of the existing combat management system was compared and the hash tree generation time of the message structures was measured to understand the effect on the operation and development process of CMS. Through this test, It was confirmed that the message structure verification method for system stability proposed in this paper can be applied to the Naval CMS.

미래 육군의 대대급이하 NCW 핵심은 기반통신장비인 TMMR(Tactical Multi Function Terminal)과 전투지휘를 위한 전장단말기인 대대급이하 전투지휘체계(B2CS)로 대표할 수 있다. 이중 TMMR은 음성과 데이터 통신이 가능토록 개발중인 무전기이다. 하지만, 군 무전기 특성상 은 엄폐 지역에서의 통신 보장을 위해 낮은 주파수 대역을 사용함에 따라 최대 지원 가능한 전송속도는 매우 한정적이다. 따라서 TMMR을 기반 통신장비로 활용하는 B2CS는 이 낮은 대역폭을 어떻게 효율적으로 사용할 것인가가 핵심이다. 따라서 본고에서는 이를 위해 군 운용환경에서의 TMMR 기반하 B2CS 운용 시 필요한 TMMR의 요구대역폭을 분석, 데이터 경량화 설계가 필요함을 확인하고, 이에 따른 B2CS에서 적용하고 있는 데이터 경량화 설계 방안을 제시하고자 한다.

In this paper, we investigate MSAP-TMFT in TICN systems that will be future NCW-based tactical networks. Although MSAP-TMFT implements the WiBro technology, we propose to design a NRC(NAT Relay Cell) that functions as a relay station and at the same time as a base station in combat environments. NRCs support extension of communication distance, increased data rate, efficient radio resource management, and survavibility of combat networks. From simulation results, we show that NRCs improve the efficacy of radio resource management and system throughput compared to the legacy systems.

In this paper, we propose an approach to get the requirement of drone acquisition for the efficient dronebot combat system using brute force algorithm. We define parameters, such as width, depth, and important surveillance area for the surveillance mission in the Army battalion and company units based on real military operation environment and brute force algorithm with 4 steps including first, next, valid, output is applied to get the requirement of drone acquisition and each drone's path planning using computer simulation. As a result, we could get the requirement of drone acquisition and each drone's path planning, the Army could utilize our proposed approach in the Army dronebot combat system. In the future research, we will study on the reliability of our proposed approach to get the requirement of drone acquisition for the efficient dronebot combat system.

Simulation based Battle Experimentation is to examine the readiness for a battle using simulation technology. It heavily relies on the weapon systems modeling and simulation. To analyze the characteristics and complexity of the weapon systems in the experiment, the modeling & simulation environment has to be able to break down the system of systems into components and make the use of high fidelity components such as real hardware in simulation. In that sense, the modular and hierarchical structure of DEVS (Discrete EVent System Specification) framework provides potentials to meet the requirements of the battle experimentation environment. This paper describes the development of the DEVS integrated development environment for Simulation based Battle Experimentation. With the design principles of easy, flexible, and fast battle simulation, the newly developed battle experimentation tool mainly consists of 3 parts - model based graphical design tool for making DEVS models and linking them with external simulators easily through diagrams, the experiment plan tool for speeding up a statistic analysis, the standard components model libraries for lego-like building up a weapon system. This noble simulation environment is to provide a means to analyze complex simulation based experiments with different levels of models mixed in a simpler and more efficient way.
