TLDR its the T95E1 we have in game but with a stabilizer and more advanced FCS
The T95 Medium project stemmed from the Tl-1 project which sought to create a tank based around the 90mm smoothbore T208 gun, designed to fire new high length to beam ration fin stabilized sabot rounds, what we of course now know as APFSDS. This project would lead to some pretty advanced tanks for the early 1950s. The version that I am talking about today is the base model T95. The T95E1 is already familiar to players of the American ground tech tree, and the T95 is extremely similar, essentially the only differences being a different mounting for the main gun and a more advanced fire control suite.
The T95 shares a hull with the T95E1, that is to say it has a heavily sloped 95mm upper front plate, a less heavily sloped 127mm lower front plate, a 560hp Continental AOI-1195 engine paired with a XTG-410 4 speed transmission.
The differences in the two vehicles present when we look at the turret. Most notably, the T95 replaces the optical coincidence range finder with the unique T53 Optical Tracking, Acquisition, and Ranging (OPTAR) System. OPTAR send out multiple pulses of incoherent infrared light and searched for returns. The major problem with this system being that incoherent light tends to scatter quite badly and as such offered multiple different returns which the gunner would have to manually sort through to find the correct return based off of a visually estimated range. The system was mounted in an armored bulb on the right side of the turret. It was only ever trialed on the T95 medium where its perceived fragility and the issues with multiple returns caused the army to drop electro-optical systems all together until the introduction of proper lasers. In game this could be modeled in one of a few ways. It could work like a normal laser range finder, it could work like an extremely quick optical or slow laser rangefinder, or it could be ignored all together and the vehicle could be modeled with just an optical rangefinder.
The other notable difference between T95E1 and T95 is the mounting of the main gun. On the T95, the T208E13 (essentially identical to the T203E9 on the T95E1, just weighted differently) was mounted a few inches further back in a rigid T191 mount. The notable change in this mount was that the T191 was fully stabilized in both azimuth and elevation. This also resulted in a slightly different, distinctively flatter gun mantlet. Attached below are a few profile shots of the vehicle and the spec sheet from Hunnicutt’s ‘Abrams: A history of the American MBT’ book
