M1 TTB was developed and built in the 1980’s, far predating the T-14 (which started development around 2010).
Object 195 (or Object 477; 1980’s) also predates the T-14.
Germany also had several crewless-turret concepts far predating the T-14, such as;
EGS - Experimentalträger Gesamtschutz (1995+) [Part of NGP (Neue Gepanzerte Platform) Program] [Test-Hull without cannon]
Related concept/proposal: KPz Leopard 3 SL (Scheitellafette) (1979)
T-14 doesnt incorporate some sort of novel concept and is by far not the first, nor only vehicle based on it.
I wouldnt consider it to be more than a prototype either, given that it 1) Isnt in large-scale production and 2) has yet to be deployed in actual combat (and confirmed to be, random claims with no evidence do not count tbh)
In that was the case than Russia and US were copying themselfs, hard for the US to need to copy the Armata when they have already done most of the things it does themselfs.
Died a while ago together with the rest of my mental health and mental stability.
it was being tested or being put into service in 2025 but it wasn’t made during that time as far as i’m aware
stuff like the 2S38 was also still in testing when it was added to WT if i remember correctly
and Jaguar (IFV) was put into service just like 3-ish years ago
so it’s not anything new by WT standards
