Marauding terrorist attacks (MTA) are fast-moving, violent incidents where assailants move through a location aiming to find and kill or injure as many people as possible. Most deaths occur within the first few minutes of the attack, before police are able to respond.

MTAs can take many forms and include a combination of the following:

  • A lone attacker, multiple attackers or multiple groups of attackers

  • Arrival at a location on foot, in a vehicle or an attack perpetrated by insiders

  • Entering without using force or forcing entry using an explosive device, a vehicle, coercion of someone with access or a combination thereof

  • Attackers armed with bladed weapons, firearms, pipe bombs, petrol bombs suicide vests or multiple weapons

Bladed weapon attacks progress less rapidly than those involving firearms since attackers must be within striking distance of their victims and expend more energy on each person.

It is more important than ever that your organisation or premises is aware of the heightened risks and adequately prepared for any potential attack. CPNI have also produced guidance to enhance the capability of SCR operators to respond to the immediate impact of a terrorist incident.

New and detailed guidance is now available providing information as to the range of measures that can be taken to minimise the impact of an attack and help save lives. These measures range from implementing simple changes to security processes and technical systems to introducing new and sophisticated security systems. This guidance sits alongside the Run Hide Tell campaign, which is designed for general members of the public. The MTA guidance is designed to help organisations develop a security plan, based on the principles of RHT.
