In your own words, this is proof that the FCAAM exists and is real.
But fun fact, the FCAAM does not exist and is only in development, Those Models are specialy done to get people intrested and get people to invest.
This right now has as much legitimity then the KH-38MT
and? there is still no evidence of use and if anything there is evidence that russian manufacturing or thermals cant keep up with demand without installing very high end systems in one time use missiles
they are installing 2nd gen systems into their newest tanks (which by their own claims are comparable to decades old western systems), I cant imagine them dedicating any production of more advanced systems for disposable missiles
its not that long ago russia specialy imported them all, i doubt they had a special area if you look at everything, resolution wise etc they lacked behind massively. More often then not russian vehicles get buffed in this area in war thunder with the way gajin handles thermal generations and resolutions.
back to my fcaams example, a model is not prove of existence of an armament
