Garbage devs, model russian vehicles based on any information that may be used to buff them, holding them to their maximum theoretical capabilities not reflected in real life. Western vehicles, F-16, Abrams, Gripen, Type-10, challenger II, Leclerc, and many others are made to have much worse stats than realistic counterparts. Devs demand that documents akin to those that are classified are released, otherwise usage of public domain documents that say similar things are not used. Big example of this is the challenger II and Abrams being shafted on things such as armor, engine power, and other such topics.
Do not support this game, get gunner heat PC, DCS, Ace combat, or dont waste your money on the game at very least. (the game is almost unplayable without premium btw)
