Oh I remember the modern conflict event despite not played much where the Russian soldiers still use the same voicelines as their WWII counterparts just like in War Thunder where it doesn’t matter whether you are in a T-34-85 or a T-90, they still use the same voicelines.
Some examples where much of the military slang(e.g. Двухсотый/200th) came only later on like several years after WWII. Imagine how weird it is to have a cold war or modern setting yet the soldiers still shout WWII era lines.
