This article is about the model introduced in Halo 5: Guardians. For the model introduced in Halo 2, see Vostu-pattern carbine.

The Mosa-pattern Carbine[1] (UNSC Type classification: Type-57 Carbine, T-57 C),[2] is the post-Covenant War successor to the Vostu-pattern carbine. It saw wide use within Jul 'Mdama's Covenant.[4]


Design details[edit]

The T-57 carbine is a versatile semi-automatic rifle renowned for its accuracy and long range. The weapon was used by various Covenant splinter groups after The Great Schism as a close-medium to medium-long range weapon. It fires at a maximum rate of 300 rounds per minute. Its color varies slightly from its predecessor, being a dark indigo as opposed to the T-51 Carbine's traditional purple.[3]

Type-57B Carbine[edit]

The T-57B uses a streamlined manufacturing process and reactive materials in place of radioisotopes for coating projectiles. It takes 7 rounds to kill a Spartan in War Games. This variant has a holoscope. It is ranked a Common REQ in Warzone simulations, and is available at Level 2 energy while giving 50 REQ points if sold.[4]

Type-57B variants[edit]

  • Rain of Oblivion: The Rain of Oblivion, whose grip has been held by a thousand heroes and a hundred villains, is an improved Carbine with fully automatic action and increased maximum spare clip count at the expense of a lower scoped range. The high rate of fire combined with relatively solid damage enable it to mow down a fully shielded spartan in 0.84 seconds. It is ranked an Uncommon REQ in Warzone simulations, and is available at Level 3 energy while giving 75 REQ points if sold.[4]
  • Blood of Suban: The Blood of Suban is an advanced Carbine that fires armor-piercing blamite shards.[4] These powerful explosive blamite needles will kill a Spartan in as little as 5 shots in 0.90 seconds.


Changes from Type-51 carbine in Halo 2: Anniversary[edit]

  • Much higher accuracy at longer ranges.
  • Slightly more bloom.
  • Magazine size increased from 18 to 20, also resulting in more reserve ammo to coincide with new magazine size (72 to 80).
  • Lighting on magazine will gradually change color from blue to red as ammunition is depleted, fulfilling a similar function as seen in Halo 2 and Halo 3.
  • Retains the 7-headshot kill of the Halo 4 version of the T-51 carbine.
  • The weapon's coloring has been altered to be more similar to that of the Beam Rifle in Halo 4.
  • Players using smart scope with the T-57 carbine now bring up its holoscope instead of a full-screen scope.
    • In addition, the aiming reticle no longer changes between hipfiring and scoped-in firing.
