What it is
STANAG 2546 is a NATO Standardization Agreement, currently Edition 2, promulgated 29 August 2018. It is not a technical specification. It is the agreement by which NATO nations commit to implement AJMedP-2, Edition A, the Allied Publication covering the allied joint medical doctrine for medical evacuation. The document's own aim is to respond to an interoperability requirement: "to maintain their national evacuation procedures as far as possible and to plan for reliable, cost-effective medical evacuation by facilitating bi- or multilateral agreements and promoting common planning, programming and training." Read on its own, STANAG 2546 requires nothing of a supplier or contractor. Its obligations run to nations and to NATO's own bodies, and the substantive medical evacuation doctrine sits in AJMedP-2, not in this cover.
Who it binds, and how
STANAG 2546 is explicit that it binds nations rather than organisations. Its letter of promulgation describes the enclosed agreement as one "which has been ratified by member nations, as reflected in the NATO Standardization Document Database (NSDD), is promulgated herewith." Under "Agreement," participating nations agree to implement AJMedP-2, Edition A - a national commitment, made by ratification, not a duty a supplier signs up to by reading this document. Ratification and implementation are kept separate: nations that have not yet reported their position are invited to "advise the NSO of their intention regarding its implementation," and national decisions on both are recorded in the NSDD. So "is STANAG 2546 mandatory" has no single answer: it depends on whether a given nation has ratified and implemented it, and this cover names no supplier, manufacturer or contractor at all.
What the agreement commits nations to
The interoperability requirement STANAG 2546 responds to is letting nations "maintain their national evacuation procedures as far as possible" while planning for "reliable, cost-effective medical evacuation by facilitating bi- or multilateral agreements and promoting common planning, programming and training." The STANAG states it "is effective upon receipt and ready to be used by the implementing nations and NATO bodies," and partner nations are separately invited to adopt it. That is national and operational machinery: a nation's medical authorities put AJMedP-2 into effect through their own orders and procedures, not a design or delivery obligation on a contractor.
A cover agreement, not the medical evacuation doctrine itself
A reader who only has STANAG 2546 in hand does not yet have the doctrine it points to. That sits in AJMedP-2, Edition A. STANAG 2546 also names the Geneva Conventions of 1949 (incorporating the Hague Protocols of 1907) and MC 0551, NATO's medical support concept for NATO Response Force operations, alongside ten further STANAGs, each paired with the Allied Publication it covers: STANAG 2087, covering AAMedP-1.5, forward aeromedical evacuation; STANAG 2228, covering AJP-4.10, allied joint doctrine for medical support; STANAG 2292, covering AJP-4.11, allied joint doctrine for NATO asset visibility; STANAG 2490, covering AJP-3, allied joint doctrine for the conduct of operations; STANAG 2523, covering AJP-3.5, allied joint doctrine for special operations; STANAG 2528, covering AJP-3.14, allied joint doctrine for force protection; STANAG 2560, covering AMedP-1.6, AMedP-1.7 and AMedP-1.8, evaluation of NATO medical treatment facilities; STANAG 2562, covering AJMedP-5, medical communications and information systems; STANAG 2563, covering AJMedP-6, the allied joint civil-military medical interface doctrine; and STANAG 3204, covering AAMedP-1.1, aeromedical evacuation. The list closes with AAP-06, the NATO glossary of terms and definitions. This edition supersedes STANAG 2546, Edition 1.
Reporting and review
National decisions on ratification and implementation are provided to the NSO, and the responses are recorded in the NATO Standardization Document Database. Nations are invited to report on their effective implementation of the STANAG in accordance with AAP-03; partner nations are separately invited to report on the adoption of the STANAG, also in accordance with AAP-03. The STANAG itself is to be reviewed at least once every five years, with the result recorded in the NSDD, and nations and NATO bodies may propose changes at any time for the tasking authority to process during that review. The agreement is supervised by the Military Committee Medical Standardization Board (MCMedSB) and the Medical Standardization Working Group (MedStd). The custodian of the STANAG is Sweden.
What it does not cover
STANAG 2546 names no clinical, organisational or command detail of its own - that content sits entirely in AJMedP-2. It also names no assessment or certification scheme: the only stated check is that the STANAG itself is reviewed periodically, not that a nation, an organisation or an individual is certified.
