Tactical net-centric systems must support the exchange of multi-media information among traditional and non-traditional
partners in a highly complex and dynamic environment across the full spectrum of operations. These systems also need
to support the establishment of both static and dynamic groups of users able to get the right information, to the right
person, at the right time, with adequate information assurance - all without compromising the ability of others to use the
limited network resources to do the same. We refer to these dynamic groups of users as Communities of Interest (CoIs).
CoIs provide a conceptual framework in which these capabilities can be implemented whilst ensuring usability, agility,
security and an overall management approach that abstracts away the complexities and challenges of the operational
environment. This paper introduces several system technologies in the areas of networking, security and information
management and puts them into an evolutionary system context that realizes maximum returns on investments,
facilitating the achievement of net-centricity in the tactical environment.
