According to some embodiments of the invention a laser directed infrared countermeasures system (hereinafter: “LDIRCM system”) is mountable on a platform. According to some embodiments of the invention, a LDIRCM system may include a plurality of sector units. Each sector unit may include at least one laser unit and a laser guidance module. The laser unit may be adapted to generate a laser beam or laser energy that is intended for jamming a guidance system of a threat. The laser unit may be coupled to the laser guidance module. The laser guidance module may be adapted to steer at least a laser beam generated by the laser unit towards a threat.
