The MicroMissile is a small air-to-air and anti-tank missile. It has a potent war head, with a plastic, napalm and phosphorous explosive and nitrogen enriched accelerants. To ensure an effective strike, it has a carbon spike on the nose, and 8 titanium fins. It is also one of the most technologically advanced missiles in the GCN's arsenal, because it has four sensors hooked up to an AI dome, to ensure accuracy, and can even be called off of a target if a mistake has been made or if anti-missile counter measures are detected.
The MicroMissile is normally carried by smaller GCN fighters which cannot hold larger munitions. For example, the SF17 Dogfish normally carries 4 Micro-Missiles in real combat scenarios. This gives these smaller fighters a fighting chance against larger, more powerful fighters.
