TL;DR: A Centurion Mk. 5 modified by Teledyne Continental Motors to mount the Low Profile Turret.
Note: To clarify, this vehicle is being suggested for the US because, outside of the initial supply of the chassis, the British have nothing to do with it. It was never marketed to them let alone tested by them as the Centurion had already been out of British service for 20+ years.
History:
The AGS program began in the early 1980s as a set of requirements put forth to replace the aging and heavily disliked M551 Sheridan. Several American companies would begin development on their own designs, Teledyne Continental Motors being one of them. TCM would begin their development in 1982, with the chassis being completed in 1983 and the turret completed in 1984. Both components would undergo their respective trials before being united in 1985 and publicly displayed at the US Army Armor Conference at Fort Knox under the name “Expeditionary Tank”. This vehicle featured a completely new and very unconventional unmanned turret, which allowed for the entirety of the crew to remain in the hull during combat, keeping all of them out of danger when in a hull-down position. The Expeditionary Tank would then be improved upon and eventually become the Teledyne AGS. When 1993 rolled around, the AGS Program was officially put to an end with FMC’s AGS entry being chosen as the TCM AGS’s autoloader had a tendency to jam. Still, seeing the potential in their unmanned turret design (now called the Low-Profile Turret (LPT)), TCM turned to the export market. The LPT would be marketed for installation on a number of vehicles, from the M60 to the Leopard 1. One of these vehicles was the Centurion and to prove that such an installation and similar installations were possible, the LPT would be installed on a single Centurion Mk. 5, which shaved off 5000kg of weight and significantly improved the firepower of the vehicle as a result. A new engine developing 908hp (At the least. Sources say that it could also have a 1050hp or 1200hp engine, however, which engine was installed in the demonstrator is unknown.) and additional spaced armor on the sides of the hull were also added. Unfortunately, this demonstrator would do little to attract customers and the vehicle would eventually be deconstructed. The hull survives to this day, resting outside of a former TCM plant in Muskegon, Michigan.
Place In-Game:
Far too often have vehicles fit for the tech tree been added as event vehicles and there’s few greater examples than the three in-game AGS tanks. Each one of those could have filled the high-tier US light tank void. To prevent any more AGS tanks being added as event vehicles, suitable alternatives must be presented. The Centurion Mk. 5 LPT is one such alternative. It’s mobility is very surprising for the hull that its based on, however, it’s still not on par with any light tank of the tier it’ll find itself in. As such, it’ll have a relatively unique playstyle as you aren’t going to be able to get into any crazy early-game positions, however, you will still be able to get to where you need to go very quickly and be able to more consistently survive autocannon fire to your hull. Your turret is also mounted much farther forward on your hull compared to the TCM AGS, allowing you to better crest ridgelines with the hull forward. As previously mentioned, the Centurion Mk. 5 LPT would be a perfect event vehicle. It provides a familiar turret on a hull unfamiliar to the US.
