A KLF (Kraft Light Fighter) is a custom LFO built for the military and used by the United Federation forces in battle. Underneath the armor lays an Archetype. As a custom LFO, it is able to lift using a ref board and fight as well but has been specifically made for usage by the Military and fitted with Military grade weapons. These KLF tend to be Mon-Soono's but there are cases of Terminus units such as used by Sawyer Team and the SOF prior to the series start. The Terminus TypeR505 is a prime example of the usage of a Terminus as a KLF.
