The BR66HB-SR is an improved and updated version of the BR55HB-SR firearm which served during the Terran-Covenant War.

Design
The BR66HB-SR is a selective fire weapon introduced to the UNSN Marine Corps in 2578 until its replacement when the UNSC joined the Federal Republic. The UNSC employs the Battle Rifle as a standard infantry rifle while still being able to engage enemies as a medium-range marksmen rifle. The BR66 has a built in electronic suite similar to the one on the MA5AR-G which allow the user of the weapon to check how many rounds remaining in current magazine, limited navigational headings, as well as several other "housekeeping" functions. The BR66 electronic systems can link up to the Neural Interface or HUD of a Marine and can display tactical information as well as providing a modulating reticule to help during a firefight. However, the electronics suite can be disrupted by the Jiralhanae EMP grenades but it does not affect the firing mechinisms.

The BR66 is visibly similar to its predecessor only being four centimetres longer. The Battle Rifle fires the new 9.5x50mm X-HP SAP tungsten rounds in a fourty eight round magazine but however the BR66 can also utilize a sixty round magazine for extended firing. The new Battle Rifle functions exactly similar to its predecessor so that there was minimal complications when the BR66 was introduced and features a built-in electronic suite which is the same as the one in the MA5AR-G.

The BR66 is exactly four centimetres longer than its predecessor, while also allowing for a ACOG to be fitted on top of the weapons modified carrying handle. However the ACOG can be replaced for a different scope allowing the user to wield the Battle Rifle in a variety of combat areas. The BR66 has an effective range of 950 metres while can still engage enemies at distance of 1800 metres.
