STANAG 4677
STANAG 4677 dismounted soldier system interoperability
Makers of dismounted soldier systems and battle management software, and defence buyers who need multinational units to exchange tactical data over a shared radio network.
STANAG 4677 is the NATO agreement that lets dismounted soldiers from different nations exchange tactical data over a shared radio network. NATO has not released it publicly; this page describes it from the Czech defence standards that implement it.

NATO has not released this STANAG publicly. It is NATO UNCLASSIFIED, and organisations that need it obtain it through their national standardization authority.
What it is
STANAG 4677 is the NATO Standardization Agreement on dismounted soldier systems standards and protocols for command, control, communications and computers (C4) interoperability, known as DSS C4 interoperability. Edition 1, promulgated 3 October 2014 under CNAD, AC/225 NAAG, LCGDSS, it covers AEP-76 edition A, issued as a general part plus five volumes: security, data model, loaned radio, information exchange mechanism and network access.
NATO has not released STANAG 4677 or AEP-76 publicly. This page describes them from a public national implementation, the family of Czech defence standards ČOS 589501 to ČOS 589506 (2016 to 2025), each of which states that it introduces one part of STANAG 4677 edition 1 and AEP-76(A) into Czech use, and from AEP-4845, a public NATO reference architecture that cites STANAG 4677 as the source of its command, control, communications and computers data model for the dismounted soldier level. A national implementation can add national requirements, so treat what follows as the Czech implementation's content, not as NATO's own text.
What the Czech implementation covers
The agreement defines the Joint Dismounted Soldier System Interoperability Network (JDSSIN), which lets national dismounted-soldier systems exchange tactical information across a coalition radio network. Each nation adds a JDSS gateway to its own C4 subsystem; the gateway translates messages using the Joint Dismounted Soldier System Data Model (JDSSDM, ČOS 589503), an information exchange mechanism (JDSSIEM, ČOS 589505) carried over NFFI version 1.3, and standard UDP, IP and Ethernet. Gateways connect to a loaned radio (ČOS 589504) that one participating nation supplies to the coalition: it needs a 100BASE-T Ethernet interface, an operational range of at least 1,500 m line of sight and 500 m in urban terrain, and, if it cannot meet the interface requirements directly, a radio adapter. The physical link between gateway and radio follows STANAG 4851, an Ethernet-over-USB connector.
The data model defines a fixed set of tactical message types - position, identification, contact/sighting, sketch, general information, casualty evacuation request, NBC, coordination and overlay - plus a receipt message for acknowledgements, each carrying a header with a message ID, timestamp and originator. ČOS 589506 sets the network access rules: connections use IPv4, and unicast and multicast addresses are assigned to each participating gateway under an addressing plan agreed between coalition states before deployment. AEP-4845, the public NATO reference architecture, lists STANAG 4677 alongside Variable Message Format (VMF) as the standards used for communication between soldier systems, including interaction with coalition and joint forces.
Classification and security responsibilities
ČOS 589502 sets NATO Restricted as the classification for information carried on the interoperability network. Each state is responsible for the security of its own JDSS gateway and its cabled connection to the loaned radio; the state supplying the loaned radio is additionally responsible for the security of the wireless network, including protecting the radio link against interference, detection and denial-of-service, and protecting the confidentiality of transmitted content.
How we help
A supplier bound by STANAG 4677 through a contract holds the obtained text through its national authority. In ComplyTrain you record the requirements that apply to you as your own requirements, give each an owner, and keep the evidence that shows you meet them against each one.

Three partners, three Member States, one evidence base
The EDF consortium rule is usually quoted as three entities from three Member States. It has a second limb about control that the word independent quietly hides, and two exceptions that disapply it entirely.
