 In addition to the USSR, SB bombers were in service with Spain, China, Czechoslovakia, Bulgaria, Germany, Slovakia, and Finland.
-After their combat debut in Spain, SBs came to be used in China from February 1938 onward. Bombers of this type participated in the Battles of Lake Khasan and Khalkhyn Gol. They were used in combat operations against Poland in September 1939 and in the war with Finland in the winter of 1939-40. When World War II began, the SB was the most popular Soviet bomber. They were extensively operated as day and night bombers, as well as scout planes, on the Soviet-German front until late 1943. They took part in the war with Japan in the Far East in August 1945.

 The Chinese Air Force used SBs until the end of World War II, as well as during the course of China's Civil War. Czechoslovakian B.71 planes were obtained by Germans and used as auxiliary and training vehicles. Bulgarian planes participated in the invasion of Yugoslavia in April 1941.

 Maybe it's because of the design of short fuselage and huge wings, or it's caused by something else, the SB 2M is super hard to control in the pitch. If you leave the stick at the deadzone, the aircraft will automatically climb or dive which will lead to a crash if unnoticed. Trimming doesn't help. For the gunner view, even though you might have the "autopilot when in gunner view" enabled, it won't help either, as it will still continuously pitch up and down like a boat. Also note that when switching to gunner view, it will sometimes uncontrollably roll to one side which will make it enter a spin quickly. Therefore this bomber is extremely frustrating to fly in Sim.
-Note: the setup with the most explosive mass is the 2x 250 kg + 2x 500 kg, but this way the two 500 kg bombs are carried under the wing roots and the two 250 kg inside the bomb bay. So if you use the default keybind (space) to open bomb bay ''and'' drop bombs, the timing will get messed up when bombing a base, since the two wing-mounted bombs will go first, ''then'' the bomb bay opens, dropping the two inside. The time between the two drops are long enough for one drop to completely miss the target. To avoid this, set up a keybind for open / close bomb bay, and drop bomb series (all bombs go at once). When approaching a base, open the bomb bay first, then drop all the bombs, they will now all hit the target.

 When bombing airfields, make sure to fly above 2,000 m to avoid the anti-aircraft artillery, as this plane is unprotected and its coolers will often get damaged, leading to the engines overheating. You should familiarise each module of the airfield to maximise the damage. The airstrip is the most visible and the easiest one to hit, however bombing it seems to halve your reward. So it is recommended to bomb everything else: hangar, fuel area, living quarters, etc. The plane hangars are probably easy, since they aren't too small.
-Given its huge wings compared to the rather skinny fuselage, it can be tricky to land as it will bounce off the ground and leap into the air again and again, no matter how slow it seems to fly. The trick is to slow it down more than any other twin-engine plane, plus set up key binds for "flaps down" and "flaps up" to replace the default "toggle flaps". This way you can use the wanted flap anytime. When approaching the airfield, make sure to descend to around 400 m when you are approximately 2 km away from the start of the runway. This is an appropriate distance to decelerate. As the airstrip occupies 1/3 of your windscreen, reduce speed to approximately 220 kph, deploy combat flaps and cancel out that extra lift by pitching down. When you are almost touching down, reduce speed to no more than 160 kph (seems dangerously slow but it can still glide safely), deploy landing gear, take-off flaps and pitch down even more so the SB 2M remains overall parallel to the ground. At the last second before touch down, make sure you are around 130 kph and deploy landing flaps. This way the bomber can land gently and softly, and will not bounce off. At last, do not constantly hold the brake. Release brake immediately once the nose starts to dip down to avoid propeller strike.
