In this paper, we discuss the current status of ROK-US wargame model interoperability and propose the future federation architecture. ROK and US Armed Forces have made an effort to make their wargame model interoperable to fulfill operational requirements since 1999. Currently, they have achieved some degree of their final goals even though there is long way to go. ROK Armed Forces is now considering future federation architecture. We propose the future federation architecture of ROK-US wargame model interoperability considering technical advantages and system availability. It will be the next federation architecture led by ROK side for the ROK Armed Forces joint exercise and ROK-US combined exercise.

Warfighting experimentation is an important process for identifying requirements against changing military environment and for verifying proposed measures for reforming military service. The wargame simulation experiment is regarded as one of the most effective means to warfighting experimentation, and its importance is increasing than ever. On the other hand, the results of wargame experiments could be unreliable due to the uncertainty involved in the experimental procedure. To improve the reliability of the experimental results, systematic experimental procedures and analysis methods must be employed, and the design and analysis of experiments technique can be used effectively for this purpose. In this paper, AWAM, a wargame simulator, is used to optimize the organization of operational troops. The simulation model describes a warfighting situation in which the 'survival rate of our force' and the 'survival rate of the enemy force' are considered as responses, 'the numbers of weapons in the squad' as control factors, and 'the uncontrollable variables of the battlefield' as noise factors. In addition, for the purpose of effective experimentation, the product array approach in which the inner and outer orthogonal arrays are crossed is adopted. Then, the signal-to-noise-ratio for each response and the desirabilities for the means and standard deviations of responses are calculated and used to determine a compromise optimal solution. The experimental procedures and analysis methods developed in this paper can provide guidelines for designing and analyzing wargame simulation experiments for similar warfighting situations.

This study investigates the wargame model application of SCO(Standard Combat Organization) concept and function for the first time. Firstly, we examine the combat organization function of wargame models suggested by published theses and research papers, and then analyze input processes and detail function of GORRAM(Ground Operation Resources Requirement Model) combat organization that is related to wargame logic. Secondly, we also reflect developed SCO algorithm and function, as follows. We defined SCO concept, and developed UI(User Interface) design and algorithm using main functions that are deducted by analyzing of existing combat organization. This algorithm consists of process, SCO, and error check algorithms. Finally, we analyzed the results of statistic verification on input time reduction and user convenience of combat organization function. Therefore, this study contributes to improving input time and user convenience of combat organization, as well as structuring new function of wargame model through the application of SCO concept and function.

Military wargame simulation models must support the HLA in order to facilitate interoperability with other simulations, and using parallel simulation engines offer efficiency in reducing system overhead generated by propelling interoperability. However, legacy military simulation model engines process events using sequential event-driven method. This is due to problems generated by parallel processing such as synchronous reference to global data domains. Additionally. using legacy simulation platforms result in insufficient utilization of multiple CPUs even if a multiple CPU system is under use. Therefore, in this paper, we propose conversing the simulation engine to an object model-based parallel simulation engine to ensure military wargame model's improved system processing capability, synchronous reference to global data domains, external simulation time processing, and the sequence of parallel-processed events during a crash recovery. The converted parallel simulation engine is designed and implemented to enable parallel execution on a multiple CPU system (SMP).

The U.S. Army is capable and ready to deploy full-spectrum armed forces anywhere in the world as we have seen in Iraq and Afghanistan. This commitment is within the realm of logistics support that the readiness to support MRE(Meal Ready to Eat), according to the environment where the operation is on going. ROKA(Republic Of Korea Army) proceeds with the program to develop and reserve various MRE under the assumption of distinctive warfare operating environment. This study investigates to determine the amount of MRE consumption within various operating environment and details are as follows. First we ponder the concept of MRE and identified problems of the existing program. Second we also establish feeding rations by the types of MRE that is the base for calculation. Third we introduce MRE consumption algorithm and formula. Fourth and last we have applied our model to the program and analyzed the results. The present state of the estimation didn't reflect various warfare operating environment. Therefore we simulates theater wargame model to determine the consumption under various warfare operating environment. The result of this study is anticipated to contribute largely to the force enhancement as it mirrors of every circumstances of operating environment.

War simulation system is a virtual space that my tactical simulation exercise is held. The data used in this system are considered sensitive and needs to be protected. But suity vulnerabilities and possible security loopholes were not considered when designing the war game simulation system. So currently the systemis highly vulnerable against hackers and data leakages. This paper proposed a security system for war game simulation system based on considering the currently vulunerabilities and possible suity leakages. The proposed security system supports security patches. In this paper, we analyze vulunerabilities of the running environment of current system and we design and implement the security system that is consisted of three components : Authentication System, Encryption System and Network Security System. The security patches are safe and there are no negative effects on the system's performance. The patches are proved to be effective and very reliable towards solving the security vulnerabilities.

This paper deals with complex system theory to describe land combat situation using EINSTein (Enhanced ISAAC Neural Simulation Tool) simulation model. Many studies have shown that existing Lanchester equations used in most wargame models does not describe changes of combat units, real land warfare situation and qualitative factors in combat. Future warfare will be a non-linear combat with various weapon system and complex combat units. EINSTein models is an agent-based simulation tool using complex system theory. We have compared and tested land combat results with Lanchester models and EINSTein models. The results have shown that EINSTein model has a possibility to apply and analyze land warfare more properly than Lanchester models.

The purpose of this paper is to propose a methodology that can estimate optimal requirement of attack helicopter Korea army will be operating in future. For estimating optimal requirement, attack helicopter's operation concept, performance, battlefield environment and enemy threat are considered. 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. In this paper, we conduct battle experiment for anti armored corps operation which reflects attack helicopter's combat effectiveness very well. As a result of simulation, the destructive rate for enemy armored corps per each attack helicopter can be calculated. In this paper, we propose optimal requirement of attack helicopter using that destructive rate for enemy armored corps.

This is a case study which establishes effective ammo issue plan and determines ammo support capability by linking various situations about ammo issue with wargame simulation. Ammo function simulation model has been developed for this matter and it has been proven that the model has significant impact on type of round, parking space for magazine, number of workers and capacity of equipment, etc. during establishing ammo issue plan and determining ammo supply capability. Also, ammo support capability varies significantly depending on tactical damage and MOPP status, etc. ASP's tactical situation, such as magazine damage, MOPP status, type of issuing round, parking space for magazine, number of workers and capacity of equipment, can be reflected when preparing an effective wartime ammo working hour issuing plan for supplying ammo to units through studies results, so that the issuing plan can be realistic and actual.
