Soviet Aircraft in War Thunder usually have machine guns with a high rate of fire and quite low ammunition capacity, which can scare numerous people away from using the Russian line, or come equipped with a small number of large-caliber cannons. Soviet planes are often known as being 'jack of all trades, but master of none.' This means that they are all rounder planes, good at everything but great at nothing. Russian fighters can become very successful if the pilot exploits his enemies weakness, and uses it against him.
Soviet Aircraft are reliable when it comes to attacking, while their defensive capabilities are narrowed down to if you can out maneuver your opponent due to weak armor, you will experience loss of tail control or loss of wings a lot.
With Weaponry commonly found near the engine, it is easier to aim in dog fights or trying to catch them on the turn. The odd planes with 20mm Cannon's is a good way to go bomber hunting with burning out there engines. Which helps when there are a few USSR planes that have this armament.
