STANAG 4816
National authorities and NATO bodies implementing NATO laser-engagement training interoperability, and the suppliers whose range and duel-simulation equipment must conform once a contract invokes it
STANAG 4816 is NATO's agreement for nations to implement the UCATT laser engagement interface, enumerations and test plan standards, so laser training equipment interoperates in coalition exercises.
STANAG 4816 is a NATO standardization agreement for Urban Combat Advanced Training Technology (UCATT), the family of standards behind laser engagement interfaces and ammunition tables used in live, laser-based combat training. The STANAG itself carries no technical specification. It commits the nations that ratify it to implement three SISO documents that hold the actual content: SISO-STD-016-00-2016, the standard for the UCATT laser engagement interface; SISO-REF-079-2025, the reference for UCATT consolidated enumerations; and SISO-REF-073-00-2020, the UCATT Laser Engagement Interface Standard test plan. Edition 2, dated 15 January 2026, is a revision of STANREC 4816, Edition 1 (13 July 2018): it adds the test plan to what the STANAG covers and replaces the enumeration reference the earlier edition pointed to.
The stated aim is to improve interoperability and integration of range instrumentation and laser-based duel simulation for live training events, especially in a coalition context, so that large coalition exercises run at higher quality and the coalition as a whole is more ready. Without a common laser coding scheme and a common set of enumerations, laser transmitters and range instrumentation fielded by different nations cannot reliably recognise a hit from another nation's equipment in a shared exercise.
A STANAG is not itself a technical specification a supplier reads and builds to. It is the agreement by which NATO nations commit to implement the documents it covers, here the three SISO standards above. That mechanism is the single thing most readers get wrong about a STANAG: it binds the nations that ratify it, not suppliers directly. A nation or a NATO body implements STANAG 4816 by issuing instructions that future laser engagement systems interfacing with NATO and other national systems in NATO training activities will conform to those SISO documents. A supplier meets it only once a national implementation, or a contract that references it, requires the equipment being built or supplied to conform, and by that point the interoperability needs to already be designed in, because a laser coding scheme and an enumeration scheme are far cheaper to build in from the start than to retrofit into fielded equipment.
Concretely, conforming means laser transmitters that are part of an instrumented combat training centre carry the laser coding defined in SISO-STD-016-00-2016, and that the enumerations defined in SISO-REF-079-2025 are implemented alongside it. Verification of an implementation may be carried out through third-party independent testing against the SISO-REF-073-00-2020 test plan. Nations and NATO bodies report their ratification and implementation details through NATO's electronic reporting tool, and STANAG 4816 is reviewed in line with AAP-03.
STANAG 4816 also names STANREC 4815 (which carries AMSP-01, the NATO Modelling and Simulation Standards Profile) and STANREC 4799 (which carries AMSP-03, the NATO reference architecture for distributed synthetic training) as related reading, not as prerequisites. A further guide, SISO-GUIDE-003-00-2016, is named in the document but sits outside our catalogue.
STANAG 4816 is an operational and technical standard, not a management system, so the work it demands happens in the day-to-day handling of laser engagement equipment and training centres rather than in software. ComplyTrain helps hold that work as evidence: a documented procedure for coding and configuring laser transmitters to SISO-STD-016-00-2016, a record that a given system's enumerations were set per SISO-REF-079-2025, training records for the staff who configure and operate the equipment, and the result of the third-party independent test against SISO-REF-073-00-2020 once one has been run.
We make no claim to implement the laser engagement interface, the enumerations or the test plan ourselves, and we do not carry out the independent testing. There is no certification to earn against STANAG 4816: what an implementation is checked against is a nation's own instructions and, where invoked, the independent test plan.
The applicable tier here, and the standards that come with it, is set by the contract and the customer's quality clause, not by us. Use the standards explorer to see what sits alongside STANAG 4816, and talk to us about the evidence a training or supply programme like this needs to hold.

Not on its own. A STANAG binds the nations that ratify it, and a nation can ratify with reservations; whether it binds a particular supplier or programme depends on whether a contract or tender invokes it, or the SISO documents it covers.
UCATT stands for Urban Combat Advanced Training Technology, the NATO family of live-training standards that the laser engagement interface and ammunition table SISO documents belong to.
Edition 2 adds SISO-REF-073-00-2020, the UCATT Laser Engagement Interface Standard test plan, to what the STANAG covers, and replaces the enumeration reference Edition 1 pointed to with SISO-REF-079-2025.
No. The document describes no accredited certification scheme. What it describes is a nation's own implementation instructions, national reporting through NATO's electronic reporting tool, and optional third-party independent testing of an implementation against the SISO-REF-073-00-2020 test plan.
Three: SISO-STD-016-00-2016 for the laser engagement interface, SISO-REF-079-2025 for the consolidated enumerations, and SISO-REF-073-00-2020 for the test plan used to verify an implementation.
