SURVICE’s electronic – Tactics, Techniques, and Procedures Guide (e-TTPG) crew recently traveled to Wright-Patterson Air Force Base and collaborated with the Ohio Air National Guard 178 SFS to film CS grenades. The team filmed the M25A2 and M7A2/3 hand grenades, providing an overview of the two grenades and their proper employment. Once completed, the video will be available for Warfighters to view on the Joint Services e-TTPG website hosted by SURVICE.
