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.

CAS(Close Air Support) is aircraft attack against hostile targets that are in close proximity to friendly forces. Immediate CAS is the mission that attack unplanned targets, and especially the distribution of suitable aircraft assets makes huge effect on the result of immediate CAS mission. But It is hard to find a previous studies on immediate CAS sortie distribution with aircraft suitability. This study suggests a methodology with aircraft suitability for immediate CAS sortie distribution. The methodology consists of 3 steps. Firstly, we analyze target information for situational awareness. Secondly, we calculate each aircraft's suitability value per each target based on the result of previous analysis. Lastly, we suggest immediate CAS sortie distribution based on the aircraft adoptability value to a decision maker. This methodology will provide not only quantitative analysis, but also decision making of immediate CAS sortie distribution more timely and effectively.

최근 몇 년 동안 나타난 러시아 해군의 부활(resurgence)은 우크라이나 사태로 본 러시아 군사력 증강을 대표하는 상징이다. 전통적으로 러시아 해양전략(Sea power)은 러시아 경제 및 안보 목표를 달성하는데 있어 핵심이었다. 러시아 해군은 주로 전략적 억제, 연안방어, 해상교통로 보호, 해외전개 그리고 군사력 투사 등의 임무를 수행한다. 특히 최근 들어 러시아 해군력이 양적 질적으로 증강되는 양상을 보이고 있으며, 이는 최근 잠수함, 수상함 그리고 해군항공 전력이 크게 증강되고 있는 현상에서 증명되고 있다. 이는 불과 몇 년 전까지 러시아 해군력에 대한 정비 및 작전 운용에 있어 많은 문제점을 보이던 부정적 사례와 현격히 다른 모습이다. 특히 푸틴 정부에 들어서 러시아 해군은 양적이며 질적인 증강뿐만이 아닌, 세계 해양에서의 원해 해군작전을 비록 지금은 간헐적이기는 하지만 활발히 실시하고 있으며, 러시아 주변국 해군과의 다양한 해군협력도 추진하고 있다. 궁극적으로 러시아 해군은 단기적으로 연안방어를 기본 임무로 수행할 것이나, 장기적으로는 과거 구소련 해군력 위상과 영향력을 부활시키기 위해 세계 무대에서의 군사적 영향력을 증진시키는 대양해군(Blue Water Navy)을 지향할 것이다.

Considering Republic of Korea that is known as the worlds one of the most compact airspace, together with development of technology of aerospace and ever-strengthening weapon systems of aircraft, is, in its reality, in a dire need for more practical infrastructure against any intrusion, of course also being mindful of the situation with the North Korea, to its national airspace or other controlled airspace. Republic of Koreas current legislative regime is unable to effectively respond to such crisis on any legal ground, and responsible government members are relying heavily on relevant military laws and regulations. Naturally, there exists strong possibility of various problems when there occurs an actual intrusion to Koreas airspace and lawful and legal resolution of the aftereffect is demanded. This article categorizes Korean peninsula and its national airspace into various kinds of airspaces; KADIZ; FIR; airspace above EEZ; airspace above contiguous zone; airspace above the high sea, and attempted to research and study these respective categories, given the unique nature of airspace and the current responsive measure. Furthermore, this article will review some of the relevant legislative actions and their sense of direction as solution to the discussed problems.

The military has been putting great efforts into applying data communication on existing voice communication systems being used in NCW(Network Centric Warfare). Data communication will be an effective choice in one of many effort to yield a minimum kill chain, comparing to legacy voice communications, when tactical units conduct their missions. However, the required budget will be enormous, in case of the replacement of a lot of legacy communication systems with new one. As a cost-effective alternative, the tactical data communication systems using the conventional radio systems instead of the development of new radio systems has been proposed. It is mandatory, though, to ensure QoS while maintaining data communication by making use of legacy radio systems already in use. This paper focuses on the performance issues experimented and analyzed for tactical data communication through the legacy radio systems as the first step towards guaranteed QoS. We have conducted various experiments such as the transmission error rate on certain tactical messages, performance evaluation of redundant transfers, the relationship between the transmission frame size and rate of error, the identification of error points in the transmission frame, and techniques to reduce the errors in both hopping and non-hopping modes. As a result of the performance experiments, The adaptive communication module which decides the redundant transmission or the Forward Error Correction(FEC) technique by analyzing channel status and current transmission status(hopping/non-hopping) of the legacy radio should be designed. the FEC technique in non-hopping, and the redundant transmission technique in hopping mode was recommended from the result of experiment with the frame size is 20bytes in non-hopping and 10Bytes frame size in hopping mode.

All of the military aircrafts in Korea Air Force are administered and operated together in the same system regardless of whether they are equipped with the data communication capability or not. The absence of the data communication capability in some of the aircrafts might increase whole kill chain hour at the point of the Network Centric Warfare achievement. Network synergy effects cannot also be desired if the section which is not connected to the network influences to the whole tactical network. Equipping aircrafts with the data communication capability could be done by upgrading the aircrafts, but resulting in high costs and long updating time. This paper is a research about the design and implementation of the UMPC based Data Link System to aircrafts that do not have the data communication capability. The proposed system grafts the UHF-based wireless modem technology and the aircraft flight mission support software onto the off-the-shelf UMPC and GPS system. The employed UHF radio equipment allows communicating tactic data with another aircrafts on the air, the ground control point, and even the Tactical Air Control Party(TACP) control vehicle that achieve missions with aircrafts. It thereby increases such capabilities as navigation aid, situation awareness, quick target identification and attack. We also applied Closed Air Support(CAS) scenarios, which is very close to the real environment, to the experiments of the proposed system. The experimental results show that the proposed system could support the data communication capability effectively and the flight mission at low costs of money and time.

Recently, there is on-going research about tactical data link system based on the legacy radio. Tactical data link based on legacy radio is operated mostly in narrow bandwidth under 25khz. Communicating traffics in nodes participated at network need to be minimized for distributing tactical data in narrow bandwidth. In addition, the data distributing structure is necessary for distributing tactical informations such as a situation awareness and so on to war fighters. However, conventional server-client system wastes a lot of time to obtain information for war fighters as user uses pull system to gather necessary information by seeking it one by one. Especially, the fighter pilot is supposed to dedicate into a situation awareness and fight mission in every seconds but seeking information of a user terminal while aircraft maneuvering affects as obstacle to concentrate engaging hostiles. therefore, push technology, the tactical data distributing system, is necessary for war fighters to receive fixed tactical data automatically without putting attention to it. This paper propose the UMPC tactical data link push framework. the UMPC tactical data link is a tactical data link system based on the legacy radio. Proposed push framework is verified by composing experiment environment and testing.

The purpose of this paper is to propose a methodology that can measure the combat effectiveness of attack helicopter which Korea army will be operating in the near future. To measure the combat effectiveness, firstly, we use a wargame model, AAsim (Army Aviation simulation), as a analytic simulation model which is used to analyze DOTMLPF and operation in army aviation field, secondly we use an Analytic Hierarchy Process by opinion of experts. For simulation and AHP, we consider anti armored corps operation reflecting attack helicopter's combat effectiveness. As a result of this study, the combat effectiveness per each attack helicopter can be measured and this combat effectiveness is useful for reasonable decision making such as selection helicopter type, quantity when acquiring new weapon system.
