S!
Some Russian squads and pilots are exceptionally good ones, like Flying Barans with VikS and all. I would regard FB as the best one, at least in original IL-2. ROSS was medicore, they were caught outright cheating in IL-2 online wars. Some their pilots were OK. Mr.X seemed to have good SA and shoots very well. Add to this the all-AP belting and PKs do happen and a lot.
About cheating. The best cheater is not the most easily seen one. That individual changes only something that gives and edge, but not too much so it can be so easily spotted. Most of it can be put to lag or similar if well done and no-one would suspect cheating. There has always been and always will be cheating and I do not expect CoD to be any different due it's easy to manipulate file structure.
Online flying is hard and requires a lot of training. Unfortunately have no time or much passion to do that these days so merely a target drone
But for a strictly offline player online is hell unless has natural talent.
