The MA37 Assault Rifle is a service rifle used by the UNSC Army during the events of Halo: Reach. It is called the MA5 Assault Rifle by other branches of the military. It is the basic model of the MA5B (used in Halo:CE), the MA5C (used in Halo 3) and the MA5K (a carbine used by the SPARTAN-IIIs during the events of Ghosts of Onyx).
