AMedP-8.6 mental healthcare during deployment

What it is

What AMedP-8.6 covers

AMedP-8.6 is the NATO Allied Medical Publication on mental healthcare during deployment. Its own aim is "to standardize for the NATO forces the general principles governing mental health (MH) support to the forward area of the theatre of operations and aid nations' interoperability." It is Edition C, Version 1, promulgated in May 2026, effective on receipt and superseding Edition B, Version 1. Nations' agreement to use it is recorded in STANAG 2564: AMedP-8.6 is the technical content, and the STANAG is what gives it force.

The document treats operational stress as different in kind from ordinary medical and surgical care. Rather than defaulting to evacuation, the emphasis is on returning a person to duty, and responsibility for managing operational stress rests with the Chain of Command (CoC), supported by a layered model of care rather than handed off to medical services alone.

The levels of support, and who provides them

Support is organised in three levels. Level 1 is a leader's own actions, self-care and buddy support, and the document treats this as the level most commonly needed. Level 2 brings in peers, primary care clinicians and mental health professionals for assessment and early intervention. Level 3 is assessment and treatment by a mental health professional (MHP). Military MH services, in the document's own words, "provide clinical, educational and advisory mental health support to Command," and MHPs are described as working to build relationships with primary care and Command so that support can reach people without necessarily removing them from their unit.

Chaplains, non-clinical social workers and behavioral health medics or technicians are named as additional members of the support team alongside clinical MHPs. A Forward Mental Health Team (FMHT) is the organisational building block that puts this close to units; the document also names aeromedical evacuation support for those who need it, a surge capability called a Mental Health Incident Response Team for crisis and mass-casualty events, and Home Nation MH support for casualties returning from theatre.

Chain of Command responsibility, and nations planning together

The psychological welfare of a deployed force is described as primarily a CoC responsibility: good leadership, competence and a caring attitude are named as protective factors, and command interest in welfare is expected to be persistent rather than reactive. Nations do not implement this in isolation. The document requires that "nations planning to operate together formulate a specific MH care plan guided by this AMedP and its Annexes," which makes multinational planning, not a single nation's own procedures, the mechanism through which the document actually gets used on an operation. Section 1.14 puts monitoring the quality of mental healthcare under national governance guidelines, and commits NATO nations to providing scalable, deployable MHP capability to support their troops. Section 1.16 requires host nations to run outcome monitoring for MH casualties, feeding that back into how the capability is resourced.

Potentially traumatic events, and acute stress reactions

Annex A sets a continuum for viewing how people respond to potentially traumatic events, moving from healthy coping through to reactions serious enough to need concentrated medical care, and restates the same three-level model of support (leaders and buddies, then peers and primary care, then a mental health professional). Annex B covers acute and operational stress reactions in more depth, and addresses NATO's approach to suicide prevention in the forward operational setting; this page names that the Annex covers suicide prevention without reproducing what it says.

Operational capability, fitness to deploy, and professional roles

Annex C establishes common procedures across NATO nations for mental health and psychiatric medication capability in forward operations, on the basis that national guidelines on delivering therapy are respected and that countries hold differing policies on deploying personnel who use psychoactive medication; this page does not reproduce the medication classes it sets as a minimum. Annex D sets out the factors nations weigh, jointly between the Chain of Command, healthcare services and the service member, when assessing fitness to deploy and fitness to remain in theatre: the operational environment, personal circumstances and duties, and factors tied to an existing mental health condition, without this page reproducing those as clinical criteria. Annex E defines a NATO Mental Health Professional job title covering several clinical specialties, states the ethical principle that MHPs "shall do no harm," and states plainly that MHPs deployed in a clinical role should not be involved in interrogation of prisoners. Expected tasks group into education and prevention, advisory support to Command, and clinical functions.

How it binds, and where nations differ

AMedP-8.6 sits under STANAG 2564, the NATO agreement recording nations' commitment to use it; that is the cover which gives the publication its force, and a nation can ratify with reservations. The document's own front matter records that Denmark, Spain, the United Kingdom, Croatia and Italy each lodged reservations at the time of promulgation, touching areas including medication policy, referral pathways and the pace at which a nation's own capability can be implemented. That is how a NATO Allied Publication like this one is adopted with national exceptions rather than word for word.

How you are evaluated

AMedP-8.6 names no certification scheme: no accredited certification body, notified body or self-declaration mechanism appears anywhere in it, and nothing here would let an organisation call itself "AMedP-8.6 certified." What functions as oversight is national. Section 1.14 puts the quality of mental healthcare under national governance guidelines, and section 1.16 requires host nations to track outcome data for MH casualties and feed it back into how the capability is resourced. Recorded national reservations are how divergence from the agreed text is captured, rather than hidden.
