ASGM-10 missile
From Halopedia, the Halo wiki
ASGM-10 Missiles are guided ordinance used by the UNSC. They are used mainly aboard small spacecraft such as the Longsword Interceptor[1]. They yield a high explosive payload and can cause serious structural damage to targets without shield . They are specialized for attacks on single ship fighters such as the Covenant Seraphs. They are reminiscent to UNSC Archer Missiles.
