Operation: FIRST STRIKE

This operation is among the UNSC's most incredible raids, conducted by only a handful of Marines and Spartans. The mission resulted in the Spartans overloading the fusion reactors on the Covenant combat station Unyielding Hierophant. With the odds on the Covenant side, the infiltration force succeeded with overwhelming results. Only weeks later the Covenant find the human homeworld, Earth, and assault it. The initial attack, led by the Prophet of Regret, is a massive failure. Though Regret found what he was most likely looking for: the coordinates for Installation 05.
