Sett utifrån ett historiskt perspektiv har utvecklingen av soldatens utrustning skett relativt långsamt. Dock har utvecklingen under det senaste decenniet gått fort framåt. I början på 2000-talet konfronterades flera länder av behovet av att utveckla soldaten och dennes personliga utrustning. Därför startade många länder egna framtida soldatsystemsprojekt. Tillgången till ett C4I-system är något som alla framtida soldatsystemsprojekt har gemensamt. Ett av C4I-systemets syfte är att underlätta för soldatens lägesuppfattning om egen position, egen enhets position och motståndarens position, samt den omgivande terrängen.Arbetets syfte är att ta reda på den militära nyttan av ett C4I-system vid bevakningstjänst. Två slutsatser som arbetet visar är att C4I-systemet bidrar till att öka soldatens förmåga för lägesuppfattning och orientering i terrängen. Tillgången till en digitalkarta underlättar orientering vid svåra förhållanden som i okänd terräng, nedsatt sikt och mörker. Den ökade lägesuppfattningsförmågan ger soldaten möjlighet att kunna skapa sig en överblick över och förståelse om den aktuella situationen, vilket leder till ökad effektivitet vid bevakningstjänst. / Seen from a historical perspective, the development of soldiers’ equipment has been relatively slow. However, developments this past decade have been faster. In the early 2000s several countries needed to develop soldiers’ personal equipment. Therefore, several countries have launched their own future soldier system project. The availability of a C4I system is something that all soldier modernization programmes have in common. One of the purposes of the C4I system is to provide the soldier situational awareness of his own position, the location of enemy and friendly forces, and the surrounding terrain. This study aims to investigate the military benefits of a C41 system for guard duty. Two conclusions of this study show that the C4I system helps enhance the soldier's situational awareness and orientation in the terrain. Access to a digital map facilitates orientation in difficult conditions in unknown terrain, poor visibility and darkness. The increased situational awareness capability gives the soldier the ability to get an overview and general knowledge about the current situation, which leads to greater efficiency during guard duty.

The Anti-Submarine Warfare (ASW) community requires a fully operational Command, Control, Communications, Computers, and Intelligence (C4I) architecture to significantly reduce time from sensor detection to defensive weapons release. The United States Navy has established programs of record leveraging space, terrestrial, and maritime communications capabilities extending to fiscal year 2015. An ordered systems engineering process was performed to derive requirements and identify Joint ASW C4I Architecture strengths and weaknesses. This architecture is dependent upon the ASW community’s ability to leverage current and planned technologies impacting C4I areas including common operational tactical picture delivery, data transmission rate, time latency, and data fusion processes. Performance forecasts for identified alternatives were modeled and simulated based on a synthesized operational scenario using the EXTEND simulation tool, and life cycle cost estimates were produced for each alternative. Based on those outcomes, one of the several alternatives is recommended for implementation. In addition, it was discovered that programmed C4I capabilities lack an integrated fielding plan and do not properly align in FY2020. Furthermore, the ASW community must make process changes to enable cross-program manager collaboration supported by a single system architect to ensure robust architectures are fielded by 2020.

Approved for public release, distribution is unlimited / Human Systems Integration Report / In the past few years, Massive Multiplayer Online Games (MMOG) have gained in popularity in the gaming industry, the public and the Department of Defense. Improvements to computer technology and the increased data transfer rate over networks have caused the potential applications for networked environments to blossom. MMOGs are a product of these improvements, as technological advancements have made it possible for the masses to gain access to virtual environments and participate. The ability to communicate and interact within the virtual environment has the potential to make MMOG technology an ideal tool for evaluating C4I systems. The design and evaluation of C4I systems with MMOGs has the potential to allow for exploration in the areas of warfighter effectiveness, emergent behavior, collective decision making, human systems integration and effective information flow. This thesis strives to illustrate how a C4I system modeled in an MMOG can aid designers in gathering insights on the effectiveness of the system in various combat situations. The insights will be gathered through the interactions of players with the modeled system in the virtual environment. The human interaction with the modeled C4I system provides the ability to capture the effects of the C4I system on the warfighter. The resultant effects of the C4I system on the warfighter directly contribute to the overall combat effectiveness of the deployed military forces. The background of MMOGs and C4I systems, and attributes of MMOGs that are desirable in evaluating C4I systems are introduced and discussed. FORCEnet, a global C4I architecture still in the conceptual phase is then used as an example to illustrate the potential rewards to using MMOGs to evaluate C4I systems. / Lieutenant, United States Navy
