The High-Powered Microwave is a directed energy weapon developed by the European Federation for combat and law enforcement applications, which transfers energy to targets via ultra-high frequency radio waves. Primarily applied in less-than-lethal mode, it causes feeling of intense burning to the targets without actual lasting physical damage.
The military-purpose lethal setting is much more fearsome and some commanders prefer not to use it as the end results are described as "horrific". The targets spontaneously combust, a rather disgusting sight and feeling.
In EndWar, both AMZ-26 Badger and Panther 1A3 can mount lethal HPM emitters, with the Badger using it as a special attack, whereas the Panther as a defensive upgrade with a follow-up upgrade to a full-blown Tactical High Energy Laser.
