HRUNTING Mark III (M1) Cyclops
From Halopedia, the Halo wiki
The HRUNTING Mark III (M1) Cyclops, also known as the Attack Cyclops, is a specialised variant of the HRUNTING Mark III (B) Cyclops. It is designed by Lethbridge Industrial and employed by the UNSC Marine Corps, while also undergoing field trials in the UNSC Army.
The Attack Cyclops is a multi-purpose assault platform designed for covert operations behind enemy lines. It is equipped with dual shoulder-mounted M12 machine guns, designed for ripping Covenant structures and vehicles apart.
The Mark III (M1) was first visualized by MEGA Brands Halo Toys as the "Attack Cyclops". The vehicle was considered a separate entity to the Mark III described on Halo Waypoint until February 2020, when Jeff Easterling confirmed the connection.
