Army Corps

Understanding the Army structure

The way the Army is structured helps it stay organised and ready for anything, whether it’s helping in emergencies, supporting peacekeeping, or defending the country.

The Corps

The British Army is organised into a number of specialist Corps. Each Corps has its own distinct role - some focus on fighting, while others on engineering and support. From frontline infantry to behind-the-scenes technical support, each Corps contributes to the Army’s overall effectiveness, ensuring it can respond rapidly and efficiently to a wide range of challenges both at home and abroad.

Regiments & Units

Inside each Corps are regiments, which are teams with their own history and identity. Regiments are made up of Units — these are the smaller groups of soldiers who train and work together. Units are the ones you’ll see out on operations, helping the Army get the job done.

Where will you fit in the Army structure?

• Your role

  Whatever your role, you will be part of a Unit. This is your core team that you will spend most of your time with while training and working.

• Your regiment

  Your Unit belongs to a specific regiment, which then sits within one of the Corps.

• Your Corps

So while your day-to-day role might involve working with your Unit on tasks or training, you’re also part of something bigger. Your Corps connects you to others doing similar work across the Army. Together, you help make sure the Army can do its job—whether that’s supporting communities, responding to emergencies, or defending the country.
