Intelligence Corps

Knowledge gives strength to the arm

The Intelligence Corps is the intelligence gathering wing of the British Army. With 1,850 Regular and 1,350 Reserve personnel, it’s one of the smallest corps in the Army – but what it lacks in size, it more than makes up for in influence.

Our Role

Now more than ever, military operations rely upon timely, accurate intelligence. The information gathered by the Intelligence Corps gives commanders the confidence to plan and execute their operations effectively.

Intelligence Corps soldiers know the how, why and where of any situation, using their guile and resourcefulness to stay one step ahead of the enemy. They play a vital role in the British Army’s decision making processes and in protecting its operations from hostile interests.

In modern warfare, knowledge really is power.
