Active Assailant Integrated Response Recommended Equipment List and Guidance for First Responders
This document details equipment recommendations and considerations for responder organizations when preparing for an integrated law enforcement, fire, rescue, and emergency medical service (EMS) response to an active assailant incident. It provides a list of standardized personal protective equipment (PPE) and medical supplies to facilitate consistency across responder organizations to the extent possible given individual jurisdictional and departmental protocols and restrictions. The information was compiled from documentation provided by responder agencies and technical experts in an attempt to harmonize equipment and terminology for U.S. responders.

C-UAS Equipment Placement Field Guidance for Responders
As agencies nationwide prepare for major upcoming events, including the FIFA World Cup and America250, counter-unmanned aircraft systems (C-UAS) planning has emerged as a critical priority. S&T’s National Urban Security Technology Laboratory (NUSTL) has recently collaborated with eight of the eleven World Cup host cities to assess sensor placement, conduct site surveys, and enhance operational strategies. Throughout these engagements, DHS teams have worked closely with state, local, tribal, and territorial (SLTT) partners to address a common challenge: the need for a practical and user-friendly tool to guide C-UAS equipment placement, enabling agencies to independently integrate it into their planning processes. To meet this need, NUSTL has developed this new resource: C-UAS Equipment Planning Field Guidance for State and Local First Responders. This resource is designed to support SLTT agencies in effective C-UAS planning and implementation for upcoming large-scale events.
