BTR’s aren’t seen all that often compared to BMP’s of various vintages. Not sure why they dominate the graph. Western nomenclature IFV/APC is in my opinion not really helpful, the key distinction is whether it has tracks, or it is wheel+amphib. (as a footnote, BMD’s straddle the two categories, but are fallen by the wayside due to lighter armor vs drones). Would be useful to quantify the contemporary 72’s and 80’s upgrade builds, which remain backbone of the RF tank force. Likewise the tank chassis derivative vehicles like TOS, BREM, SPG’s, SAM’s, and bridge-layers, which together may well outnumber the tank itself in current production- esp for the T90 chassis. Lastly, Oryx is a far from reliable source, it has led too many observers astray.
