NATO’s multinational battlegroups need help transitioning verified technical interchangeability into national policies that allow them to operate, train, and maintain readiness from a common ammunition stockpile that is legally permitted and safe to use. In February and March of this year, the NATO Standardization Office coordinated with a team from the US Army War College (USAWC) to conduct a ground-level survey within three of NATO’s eight multinational battlegroups. The team’s most salient observation was this: battle group key leaders believe that national policies prevent ammunition exchange within their multinational formation. This perception may hinder a multinational unit’s wartime interoperability, and certainly impedes operational efficiency in peacetime.
