Participants interacted with the Chief of Defence Staff, the Chief of the Naval Staff, the Chief of Integrated Defence Staff, and the Vice Chiefs of the Army and Air Staff.
Discussions covered jointness, ongoing conflicts, defence production, artificial intelligence, robotics and quantum computing, and non-kinetic domains such as cognitive warfare and counter-disinformation.

General Awareness > Tri-service organisations, appointments and defence reforms
The ability of the Army, Navy and Air Force to plan, train and fight as one force rather than three coordinated ones; the stated objective of HQ IDS.
Action that does not rely on physical force - cyber operations, information and cognitive operations, strategic communication and disinformation.
Hostile activity deliberately kept below the threshold of open armed conflict, so that it is hard to attribute and hard to answer militarily.
