Civil-military unity of effort has been an essential yet frustrating elusive requirement for success in post-cold-war peace operations. The need to coordinate, collaborate, and share information between civilian and military entities is on the rise and deemed essential requirements for success. Today’s information and communications technologies serve to facilitate the exchange of information among the disparate players of peace operations but the ability to actually realize open information sharing in real-world coalition operations remains problematic. The integration of relevant information and the timely dissemination of the processed information to interested parties in the field is well within the realities of today’s technology. Increased civil-military involvement in peacekeeping and humanitarian operations around the world is matched in part by the rise in the number and complexity of these situations. There are many more actors on today’s peace operations landscape with competing as well as common interests and expectations. The need to improve cooperation, coordination, and more open information sharing is on the rise. Efforts to improve and facilitate more open working together and information sharing among the disparate participants must overcome a continuing lack of trust among the civil-military actors, obsolete national and international policies, unrealistic legal and funding constraints, and outdated organization cultural traditions and behavior patterns. Additionally, all actors need to better understand each other and the roles they can and should play in an increasingly complex operational environment. In order to obtain closure and improve the future situation, the actors must develop relationships based on mutual trust, and there must be a clear understanding that cooperation, coordination, and information sharing is a two-way street. In reality, inefficiencies are inherent in any multilateral activity, and competing interests and fear of loss of power and prestige make unity of effort a desired objective, but also one that will be difficult to achieve. Furthermore, information is power and can be an effective means to an end, but only if it can be interpreted, shared, and used effectively for military, political, or civil use. Information can also help reduce uncertainty and provide those that possess it a decided advantage in the decisionmaking process. There continues to be a general lack of trust among the players, coupled with the lack of a shared understanding of the added value through more open and improved information sharing. Information sharing among the actors on the peace operations landscape continues to be largely a manual process. These obstacles need to be recognized and, to the extent possible, practical recommendations developed for ameliorating them. Application of new technology must go beyond simply modernizing existing practices and capabilities. The civil-military community needs to look at new ways of doing business and how the rapidly advancing information technology can be used to leverage the power of information to help achieve timely and appropriate success of peace operations. The patterns of conflict for the post-cold-war environment are changing and so are the approaches to military command and control. Advances in information technology have enabled organizations and individuals to more effectively leverage the power of information; yet for coalition operations where information sharing is essential to meet mission needs, it continues to be problematic. The issue is not technology, but largely the will on the part of organizations and individuals to make it happen. There is also a number of policy, doctrine, C4ISR systems, cultural, and environmental challenges that influence the ability to achieve more open sharing of information in coalition operations.
