The BR85HB Battle Rifle (or known as the BR85 Heavy Barrel Service Rifle (BR85HB SR)) is a burst-fire weapon used in the 5th Marine Expeditionary Unit. It is granted to players upon becoming a NCO. Up until October 10-11, 2015, the Halo 4 variation of the weapon was used until it was replaced by it's variation seen in Halo 5: Guardians.
The Battle rifle behaves similarly as it appeared in Halo 4 (and later Halo 5: Guardians) with the exception of being recreated in and thus suffer the disadvantages of the Source Engine.
- The fact that only NCOs+ are eligible to be issued the battle rifle without donating can be considered lore-breaking due to the Battle rifle and it's variants being canoncally standard issue to all Marine personel.
- The use of the Halo 5: Guardians BR's smart scope can be considered slightly troublesome due to idle animations playing while it's scope is in use.
