Sabre is a variation of the Combat Vehicle Reconnaissance (Tracked), featuring the turret from a wheeled Fox Armoured Reconnaissance Vehicle mounted on the hull of a tracked FV101 Scorpion.

As such, modifications were made to the turret of the Sabre to include redesigned smoke grenade launchers and the L94A1 7.62 mm chain gun replacing the standard 7.62 mm FN MAG general-purpose machine gun, for anti-personnel use.

An ammunition hopper sits on the side of the machine gun allowing the weapon to be more quickly reloaded than a belt-fed machine gun.

The UK initiated the Tactical Reconnaissance Armoured Combat Equipment Requirement (TRACER) to replace the Sabre and Scimitar.
