A Kinetic Energy Vest served as a robust blast vest for soldiers operating an Emperor-4 beam tube. Constructed with composite ceramics across its surface, the vest's purpose was to neutralize and spread out the kinetic force of impacting projectiles. It formed an integral part of the soldier's gear, providing a mounting point for the backpack power cell. Furthermore, the Kinetic Energy Vest integrated a comlink offering a communication range of four kilometers, along with a homing beacon to aid in location by recovery teams, and a backup power source.
