Marauding terrorist attack (MTA): prehospital considerations.

Terrorist attacks are increasing each year as are the number of deaths associated with them. Recent incidents have seen a shift in tactics with the use of multiple terrorists across multiple locations with firearms or knives, referred to as the marauding terrorist attack. These methods are becoming more prevalent alongside the use of vehicles deliberately aimed at pedestrians. Management of these incidents can be challenging. Not only it involves a large number of casualties but also the management of a dynamic scene in terms of both location and threat from attack. In order to improve response, and potentially outcomes, a system or response needs to have preplanned and practised procedures in place. This article reviews major incident management for those unfamiliar with current prehospital practice and details some of the findings from recent marauding terrorist firearm attacks, in particular the evolution of newer scene management tools such as 3 Echo and THREAT. It highlights the importance of haemorrhage control and the public initiatives focusing on actions during a terrorist incident.
