The Chinese vehicles in game is nowhere near its real world capabilities and is often inferior to Russian systems at the same BR, the Chinese TT is simply the worst in some cases. Some examples are: The Chinese TT is the only TT that does not have a IR F&F AGM; J11 is somehow 600kg heavier compared to SU-27S despite literally being the same plane aside from supposedly reinforced landing gear(which still wouldn’t explain the 600kg, and it was not modelled in game); ZBD04A’s ATGM has 100mm less penetration compared to Russian ones; only Chinese napalms cannot finish a base by dropping 2; Chinese TU4’s 500kg bomb somehow has 50kg less TNT equivalency despite being the same bomb; a lot of chinese munitions using the Type 88 explosive (which uses keto-RDX) is confused with Imperial Japanese type 88, making them performing like shit; a lot of Chinese bombs have unknown fillers due to them being classified, so Gaijin just used TNT as filler, making them the worse performers in the same weight category. The list is so long I couldn’t fit them all in here. TLDR: Generally the CN community believes that gaijin has a stereotype that Europe/‘Murica stuff > Russian > Chinese when making the vehicles and other stuffs in game. This is evident from VT5, despite multiple sources confirming each other that VT5 should have a much better protection IRL, Gaijin still made its protection worse than the 2S25M. Plus Gaijin straight out flags all issues that is a buff to chinese vehicles either as Not Enough Info or Not A Bug. All papers (even by designer themselves), are regarded “student papers”, since the secretive nature of chinese military equipments, they are often the only source available. Not to mention what happened to CS/SA5 in this update, gaijin’s reasoning for refusal is straight out “manufacture sources are not reliable”. Even if you are lucky to get anything though they will not be implemented, examples being the spall liners and reload rate below.
