Mission Description and Budget Item Justification Special Tactics (ST) is a human-based weapon system, comprised of both human and equipment capabilities formulated to provide the Air Force and Joint Force with support across the following missions: Global Access, Precision Strike, and Personnel Recovery (PR); with additional focus on Electromagnetic Spectrum Operations (EMSO), Counter-Unmanned Aircraft Systems (UAS), and Ground-based Suppression of Enemy Air Defenses (SEAD). ST is employed by Air Force Special Operations Command (AFSOC) across three distinct operator specialties: Combat Control, Pararescue, and Special Reconnaissance. ST, along with the Guardian Angel and Tactical Air Control Party (TACP) weapon systems, collectively make up Air Force Special Warfare (AFSPECWAR), formerly known as Battlefield Airmen. Special Warfare Acquisition, Growth and Refresh (SWAGR) is the program of record to develop, integrate, test, procure and field the latest technology and equipment across a wide range of capabilities to ensure AFSPECWAR ST operators can achieve the mission sets outlined above. Specifically, SWAGR delivers modernized capability in the areas of body-worn hardware/software, tactical communications, ground mobility, small UAS, visual augmentation, maritime, special reconnaissance, technical recovery, and assault zones. Funding will provide for continued software development and modernization of the body-worn kit to enhance situational awareness, communication, information management, and airpower integration for ST operators in the battlespace. These enhancements will improve the ability recognize, identify, range, nominate, and designate targets during both day and night operations. Improvements will also significantly reduce the time required to find, track, fix targets, and engage the enemy by attacking adversary signals of interest, providing highly accurate target grid coordinates in three dimensions, generating target imagery both pre- and post-strike, and transmitting target data to Command and Control centers.

ST is employed by Air Force Special Operations Command (AFSOC) across three distinct operator specialties: Combat Control, Pararescue, and Special Reconnaissance.

Special Warfare Acquisition Growth and Refresh (SWAGR) awarded a competitive Systems Engineering and Integration contract in May FY 2023 to continue development and modernization of the software on the body worn kit from the prior machine-to-machine (M2M) software development contract. This effort includes system engineering, design, integration, and fielding support for M2M software. The above efforts may change based on the need to support current Air Force mission requirements.
