The DSMA Notice System

Welcome to the website of the Defence and Security Media Advisory (DSMA) Committee

Standing Notice 1

Military Operations, Plans & Capabilities


This Notice aims to prevent the inadvertent disclosure of information which would improve an adversary’s knowledge and understanding of the UK’s military plans, current operations and capabilities including details of cyber activity, technology, methods and techniques in support of the Defence and Security of the UK.

Such disclosure could improve an adversary’s knowledge in ways which could put UK forces at a disadvantage.  At a minimum, this would increase the risk to UK personnel and undermine the effectiveness of UK operations.  In more acute cases, this could lead to the loss of UK lives and endanger national security.
