What it is
An agreement, not the doctrine itself
STANAG 2561 is the NATO standardization agreement by which member nations commit to implement AJMedP-4, Edition B, Allied joint medical force health protection doctrine. A STANAG is not itself a technical document: it is the agreement by which NATO nations commit to implement one, and the substance sits in the Allied Publication it covers. This cover's own aim is "to respond to the following interoperability requirements", stated here as the intent "to provide basic evidence-based information, standards and approaches to force health protection in support of military operations". Read plainly, that means the force health protection doctrine itself, evidence-based information, standards and approaches for protecting the health of a deployed force, is what AJMedP-4 covers, not this agreement.
Participating nations "agree to implement the following standard", named as AJMedP-4, Edition B. The cover lists no other related document beside the one it covers.
How a nation implements it
The mechanism that matters for a supplier: a STANAG binds a nation, not a company. "This STANAG is effective upon receipt for use by the participating nations and NATO bodies", but effective is not the same as implemented. Nations "are invited to examine their ratification of the STANAG and, if they have not already done so, advise the NSO of their intention regarding its ratification and implementation", with responses recorded in the NATO Standardization Document Database. A nation only gives the agreement domestic force once it "has issued the necessary orders or instructions to authorities and units concerned".
Reporting is not symmetric. Allies and NATO bodies "shall provide implementation details through the electronic reporting tool", a standing obligation, while partner nations are only invited to report the same way. No NATO effective date is set: the document records it as "Not applicable".
What it does not do
The agreement names no certification body, no notified body and no audit of any organisation. The only check it describes is of itself: it "is to be reviewed in accordance with AAP-03", with the result "recorded within the NSDD". That is a standardization review run through NATO's own machinery, not an assessment of a company, and nothing here sets an obligation directly on a supplier or a manufacturer.
Edition, tasking authority and custodian
This is Edition 3, promulgated 14 November 2025, and it "supersedes the following document: STANAG 2561, Edition 2, dated 27 July 2018". It covers AJMedP-4, Edition B, which has its own record in this catalogue; the substance of the doctrine, the evidence-based information, standards and approaches to force health protection, is described there, not repeated here.
The agreement is supervised under the authority of COMEDS, MCMedSB, MedStd and FHP. Comments on it go to the NATO Standardization Office, which also publishes it. STANAG 2561 itself is unclassified and free of charge - NATO's Standardization Document Database lists it, and we do not host a copy or sell it.
