Across our UK network we have specialist officers and staff dedicated to stopping those who seek to do us harm.
If the worst happens, we want to respond as quickly and efficiently as possible. To help us prepare for attacks, we regularly test our methods by holding exercises.
We do this in partnership with other emergency services, local and national government departments and the military. This helps us understand the way each organisation works so we can come together for a major incident and act as one.
Many exercises are held in public buildings to make them as realistic as possible.
We also run campaigns to make sure that the public are given practical advice on what to do in the rare event of an attack. Information, expert advice and materials are available on our ACT: Action Counters Terrorism website.
