BMPT is the designation for both the prototype we have in-game aswell as the production version.
The BMPT prototype predates that of BMPT72, BMPT72 is a later development (first brochures from uralvagonzavod that I have are from ±2012), which uses a different turret than the BMPT prototype aswell as a different chassis/hull.
The production version of BMPT utilizes the hull of the prototype BMPT (our ingame-variant essentially) and the upgraded turret that is also seen on the BMPT72.
BMPT (“Terminator 1”, old turret / 5 crew) → prototype/exported
BMPT-72 (aka. “Terminator 2”, old T72 hull + new turret / 3 crew) → export/retrofit for old T72s
BMPT model 2017 (Terminator 1 hull + Terminator 2 turret) → “updated” russian service variant
What I still don’t get is since the model 2017 is the new version seen in Ukraine, the BMPT-72 is export and the Terminator 1 is just a prototype. Which one did they use before model 2017. Online it says they used the 5-crew version but that is the prototype. Apperantly they didn’t use any BMPTs until the model 2017.
The whole naming thingy is driving me over the edge
