Background: The M551A1 TTS (Tank, Thermal Sight) was developed from the M551 Sheridan, an air-droppable light tank which originally entered US Army service in 1969. This vehicle was designed to act in a scouting role in American airborne units, and was very light, capable of landing by parachute and supporting infantry that had arrived in a similar manner. It quickly became clear that the original optics and fire control systems were rather dated. The 1971 M551A1 upgrade added a laser rangefinder to improve the vehicle’s first hit accuracy.
Development of the M551A1 TTS continued through the 80s, which sought to improve scouting capability and acquisition of the vehicle by adding a FLIR optic for the gunner. The thermal sight on the M551A1 TTS was the same as the thermal sight on the M60A3 TTS. The first TTS Sheridans were accepted in 1989, and participated in the Panama and Gulf War conflicts. TTS Sheridans served actively in the US Army until 1996, and these vehicles would continue to perform in the OPFOR role until 2003, when the remaining vehicles were scrapped or sent to museums. None were ever exported.

Reasons to add: This vehicle (upgrade package, really) would be a massively improved version of the M551 Sheridan we already have in War Thunder, with improved scouting capability thanks to its gen 1 thermal sight and far better first-hit probability thanks to its laser rangefinder. In most other respects, it is the same as the M551 light tank already present in War Thunder. It would still need to be careful in its engagements - the tank is very poorly armored, and the HEAT shells are unreliable with regards to damage. The user may find the HE shells or missiles more reliable.
Adding this vehicle would also would mean the US tech tree would have a “bridge” between the 1960s production M551 Sheridans and the more modern light tanks like the XM8 and HSTV-L, which have thermal sights, laser rangefinders and modern APFSDS-T ammunition.
