STANAG 4406 Edition 1 (formerly known as Version 3.0) consists of the following sections:
STANAG 4406 was first published in March 1999 and in that time alot of experience has been gained in the implementation of STANAG 4406 Ed 1 systems, from both NATO and vendors. An Implementer's Guide is provided that both clarifies and amends the base standard. It must be read in conjunction with the main standard when implementing a STANAG 4406 system as a number of significant changes have been made, for example, the preferred security labelling mechanism.
Note that the WG5 website provides a reference to version 1.5 of March 2000 of the Implementer's Guide, but the latest version is actually version 1.11 of 17th January 2005.
