Armed officers have explained they are prepared to run towards danger to protect civilians in the event of a terrorist attack in London.
The Metropolitan Police has released footage to allow people to find out more about the role of these brave officers who volunteer to carry a firearm and stand on the frontline and confront any threat to the public in London.
The message behind the video is 'They do this for you, for London, for all of us'.
These are the men and women who patrol the streets day-to-day as ordinary police officers and deal with ordinary police incidents, but if the public are at threat from a gun or weapon-related incident they will be first to be deployed to the scene.
They are paid no extra for putting their lives on the line and simply committed to fulfilling their duty to keep Londoners and visitors to the country safe.
This was shown last week on the same day as the announcement made by the Mayor of London Sadiq Khan and Police Commissioner Sir Bernard Hogan-Howe that 600 additional firearms officers will be deployed on the capital's streets, when an attack took place in Russell Square on August 3.
Armed officers were sent to Russell Square with limited information within six minutes of the first 999 call made by a member of the public – not knowing if it was an act of terrorism they were about to walk into.
A woman was killed in the frenzied knife attack in which five other people were also stabbed, and a suspect was detained at the scene.
In recent weeks top police chiefs have urged the public to 'Run, Hide, Tell' in a critical incident, while firearms officers face the daunting prospect of running the opposite way to confront the threat.
Sir Hogan-Howe has previously said it is a case of “when not if” terrorists will strike , while Scotland Yard assistant commissioner Mark Rowley has told the public to “run as far as possible” if terrorists strike.
The response time to serious threats will be quicker with more armed officers patrolling the streets, with the first batch of new recruits now being fully trained operationally ready.
Armed officers are required to complete a basic nine-week training course but training continues throughout their careers.
