A STANAG is a NATO Standardization Agreement — a document that records member nations' agreement to use common procedures, equipment, terminology or data formats so allied forces can operate together. Many implement an allied publication such as APP-6 for symbology.

Why are STANAG numbers cited so often?

Because they give a precise, language-neutral reference to a specific interoperability standard. Saying STANAG 4569 is unambiguous about which armour protection scheme is meant, across every NATO nation and supplier.

What does STANAG 4569 cover?

STANAG 4569 defines protection levels (Levels 1 to 6) for the occupants of logistic and light armoured vehicles against ballistic, blast and mine threats. Vehicle armour is frequently specified by its STANAG 4569 level.

STANAG 6001 defines the Standardized Language Profile, a scale from 0 to 5 rating proficiency in listening, speaking, reading and writing. NATO language requirements and many military and defence jobs quote an SLP such as 3-3-3-3.

A quick map of NATO standardisation agreements

NATO Standardization Agreements (STANAGs) let allied nations use common equipment, procedures, formats and terminology. They are referenced everywhere from ammunition specifications to armour ratings, rank codes and language requirements. This reference lists commonly cited STANAGs by number, title and the subject area each one standardises.

How it works

Each STANAG has a number and records agreement on a specific standard, often implementing a broader allied publication. The number is the canonical, language-neutral handle that everyone cites:

STANAG 2116  NATO rank codes        OF-1..OF-10 / OR-1..OR-9
STANAG 4172  5.56mm NATO ammunition interoperable small-arms round
STANAG 4569  Vehicle protection     ballistic / blast levels 1..6
STANAG 6001  Language proficiency   Standardized Language Profile 0..5

Search filters across the number, title and subject at once, so a query like ammunition or language surfaces every relevant agreement.

Tips and notes

STANAGs are revised by edition; always confirm the current edition before citing one formally.
Many implement an allied publication (APP-6 symbology, ADatP-3 message text), which carries the detailed content.
Equipment is often specified directly by STANAG — armour by STANAG 4569 level, ammunition by STANAG 4172 / 2310.
