Within NATO there are more than 20 accredited COE’s. They provide expertise on many different topics, ranging from ‘military medicine’ to ‘operating in confined and shallow waters’. Although the areas of expertise can differ, we all have a common goal of improving NATO and more or less the same ‘modus operandi’. In this light we have a lot of cooperation mainly on supporting issues that every COE has to deal with like Budget Financing, Command and Control Systems and Communications.
