Background Information: N/a, appeared recently after the massive blitzkrieg operation by the Chinese Federation and Britannia. Has only appeared in engagements against the Chinese Federation, Britannia, and the Order of the Black Knights. They have been known to appear from nowhere, engage the superior force, then engage both forces, and vanish when withdrawing. None of their number have been caught or forced into like situation(s).
They seemed to have been formed or at least began establishment prior to the SAZJ, and gained momentum during the years of the SAZJ and spiked during the one year war and the few years following. The EF seems to have acquired technology belonging to the Black Knights and Britannia through the means of salvaging, the black market, or other means unknown. They have surprisingly, a good deal of funding, but seem to be more self sustaining than relying on outside factors for support.
