Sabre is a variation of the Combat Vehicle Reconnaissance (Tracked), featuring the turret from a Fox reconnaissance vehicle mounted on the hull of a Scorpion. This hybrid vehicle was introduced as a less expensive way of producing a similar vehicle to the FV107 Scimitar, but with a slightly lower profile turret. It was brought into service in 1995. During initial combat exercises, several flaws were identified. In particular, the vehicle lacked defensive capabilities. 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 general-purpose machine gun, for anti-personnel use. An ammunition hopper sits on the side of the machine gun allowing the weapon to be quickly reloaded compa
