National policies related to JC3IEDM The UK Ministry of Defence has mandated JC3IEDM as the C2 Information Exchange Model, in Joint Service Publication (JSP) 602:1007, for use on all systems and/or projects exchanging C2 information within and interoperating with the Land Environment at a Strategic and Operational Level. It is strongly recommended for other environments and mandated for all environments at the Tactical level. JSP 602:1005 for Collaborative Services has also mandated JC3IEDM in the tactical domain for all systems/projects providing data sharing collaborative services.
