Leonidas
Leonidas is a type of advanced weapon system that uses powerful microwave energy to disable or destroy enemy drones, especially drone swarms. It's designed to protect personnel and critical assets by disrupting or 'frying' the electronics of hostile unmanned aircraft.

TECHNICAL DEFINITION
Leonidas is a C-UAS (Counter-Unmanned Aircraft Systems) directed energy weapon system developed by Epirus, leveraging high-power microwave (HPM) technology to neutralize or disable hostile drones and swarms through electronic warfare and soft-kill disruption. Its primary function is robust force protection and critical asset defense against evolving aerial threats.
BACKGROUND
300 is a 1998 limited series comic book written and illustrated by Frank Miller with painted colors by Lynn Varley.
