Radar (Radio Detection and Ranging) is a surveillance technology used heavily during the War against the GLA. As it's de-achronized name implies, radar made use of simple radio and microwave transmissions to reveal key locations to commanders allowing them to command and guide their forces with precision and efficiency. On top of this, the availability of a radar station granted commanders access to secret communication channels with their respective militaries, opening availability to special technologies and soldier divisions to support their war efforts.
