What it is
STANAG 6511 is the NATO standardization agreement covering AJP-3.7, Allied joint doctrine for the recovery of personnel in a hostile environment, edition B. The STANAG is not the doctrine itself: it is the agreement by which NATO nations ratify AJP-3.7 and commit to implement it. This is edition 2 of STANAG 6511, promulgated 12 June 2025, superseding edition 1, dated 23 February 2016.
Ratification and implementation are separate steps
Ratifying STANAG 6511 is a national act. A nation examines its own position on the agreement and advises the NATO Standardization Office whether and how it intends to ratify and implement it, and its response is recorded in the NATO Standardization Documents Database (NSDD).
Implementation follows, and is distinct from ratification. A nation or NATO body has implemented the STANAG once it has issued instructions bringing its own standard operating procedures, and its education and training policy, into line with AJP-3.7's recommendations, and reported those details through the electronic reporting tool. Partner nations are invited to report implementation on the same basis, without the ratification obligation that applies to member nations. The agreement names no NATO Effective Date, so it takes effect for a participating nation or NATO body on receipt rather than on a fixed calendar date.
Because ratification and implementation are two different things reported at two different times, a nation can have ratified STANAG 6511 without yet having implemented it, and a contract that cites the STANAG is not by itself evidence that AJP-3.7 has been implemented in a particular unit or programme.
What the agreement covers
STANAG 6511 exists to standardize interoperability for recovering personnel isolated in a hostile environment during NATO operations, by pointing nations at a single doctrine, AJP-3.7, rather than leaving each nation to write its own. The detailed doctrine, including how recovery is organized, planned and executed, sits in AJP-3.7 itself, not in this agreement.
Where it fits alongside other doctrine
STANAG 6511 names several related documents. STANAG 2437 covers AJP-01, AJP-01, the Allied joint doctrine that sits above it. STANAG 2490 covers AJP-3, Allied joint doctrine for the conduct of operations, and STANAG 2526 covers AJP-5, Allied joint doctrine for the planning of operations. None of these is cited as a binding requirement within STANAG 6511's own text; they are named as related doctrine that sits alongside it. AAP-03 governs the procedure by which STANAG 6511 itself is reviewed, with the result recorded in the NSDD.
How it is obtained and evaluated
STANAG 6511 is a NATO non-classified document, free of charge. NATO does not sell its standardization documents at any stage; it can be retrieved from the NATO Standardization Documents Database or through a national standardization authority.
There is no certification scheme attached to STANAG 6511, and no third party audits an organisation against it. What the agreement provides for is national self-reporting: a nation or NATO body reports its own ratification position and, separately, its own implementation details, both recorded in the NSDD. The only review the agreement names is the periodic one carried out in accordance with AAP-03.
