A protective garment contains a projectile detection device, in addition to impact and breach resistant materials for protecting the wearer. An arrangement of force sensitive regions defines a grid arrangement responsive to an incoming projectile. The force sensitive regions include pressure sensitive or piezoelectric characteristics such that an impact varies the electrical response of each region. A detection circuit connects to each region for sampling. A sampling of the regions computes a high velocity impact by a sudden change in the sensed electrical characteristics, such as a sudden drop in resistance between two planer sheets. The grid arrangement identifies the impact placement on the garment, and can be mapped to anatomical regions to evaluate a severity. Placement and impact force, along with GPS coordinates of the wearer, are transmitted by the detection circuit and/or in conjunction with an app on a mobile device of the wearer for alerting first responders.
