Scorpion missile

Were you looking for the Scorpion, the UNSC Main Battle Tank?

Scorpion Missiles are a type of explosive ordnance used by the UNSC. These weapons are commonly mounted on the UNSC's SkyHawk jets and Longsword fighters for use in combat against the Covenant. They are equipped with motion tracking systems and proximity detonators, that greatly increase their chances of crippling or destroying a target. They are also able to attain high cruising speeds and are very accurate, thanks to their advanced guidance systems, which quickly locate and lock onto a target. Thanks to these state-of-the art features Scorpion Rockets are capable of destroying even the most heavily armored of tanks and fighters.

Appearances
In Halo: The Fall of Reach, Colonel James Ackerson dispatched a SkyHawk to attack SPARTAN-117 and Cortana while the pair were on a testing run, in an effort to kill these threats to Ackerson's success. The SkyHawk launched a Scorpion Missile at the Spartan, but it failed to kill him, a result of John 117 literally swatting the rocket away with his energy shielded arm, a unique improvisation on the part of the Chief, made possible only by the aid of Cortana.
