The intent of this paper is to highlight the technical features and enhancements that are included within SCA 4.1 and describe how the inclusion of those capabilities would benefit an SCA system stakeholder relative to that of an equivalent SCA 2.2.2 implementation. Although this paper highlights the key new SCA 4.1 features, it is not intended to be a primer for the specification. New users might find that the briefing materials on the Joint Tactical Networking Center (JTNC) public web page are a better starting point to learn about the SCA.
