MASTS Documentation and Training Clarity

Recommendation

All documents and training relating to Mobile Armed Support to Surveillance (MASTS) should: clearly differentiate between MASTS as an operational method of supporting surveillance (and delivering a standard range of tactical options), and the additional tactical options of 'intervention' and 'interception' that MASTS trained authorised firearms officers (AFOs) can deliver; make clear that a MASTS deployment authorisation should not be taken to imply that 'intervention' or 'interception' are preauthorised or preferred tactical outcomes; note that decisive action by MASTS officers is a high-risk option and explain what factors lead to higher risks (for example, the presence of a subject inside a stationary vehicle); and make clear that the reasons for any strategic or tactical command decision in a firearms operation (including any decision to authorise such an operation) must be recorded at the time the decision is made unless it is impracticable to do so, in which case such reasons, together with a full explanation for not recording them at the time, must be recorded as soon as possible.

Published Evidence Summary
The following publicly available evidence relates to this recommendation:
The National Police Chiefs Council (NPCC) took responsibility for this recommendation, which involved a review of Authorised Professional Practice (APP), the National Police Firearms Training Curriculum (NPFTC), and associated policy (Government Response to the Anthony Grainger Public Inquiry, May 2020). In May 2020, the government reported that a review of the Mobile Armed Support to Surveillance (MASTS) module of the NPFTC and its guidance specifically addressed some aspects of the recommendation, with further work planned for completion by 31 July 2020. However, no public update confirming the full completion of this work or the publication of revised documentation and training has been identified since May 2020.

28. This recommendation is complex and has required a review of Authorised Professional Practice (APP), the National Police Firearms Training Curriculum (NPFTC) and associated policy and doctrine. NPCC have decided to take responsibility, given the important national implications and dependencies. 29. The College of Policing and NPCC's review of the relevant Mobile Armed Support to Surveillance (MASTS) module of the NPFTC and the guidance therein specifically addresses some of the above recommendations, but certain aspects require further work. The NPFTC was amended in 2015 to clarify that MASTS should be understood as an operational platform from which a number of options can be delivered rather than as a tactic. The outcome of decisive armed intervention (using firearms to challenge a subject) should not be taken as inevitable or pre-authorised. 30. These actions will ensure that there is a greater differentiation, and recognition of the higher risks, between the deployment of MASTS as support to surveillance and as an additional tactic of decisive armed intervention and interception. The provisional target is to complete work by 31 July 2020.
