Interesting. This picture is going in a bunch of different stylistic directions at once. I don't recognize the specific type of the aircraft, but its style and the clothes the airmen are wearing are very evocative of World War I; but the character in the foreground seems to have a WWII-pattern Thompson gun, while her battle dress and gear have kind of a Wehrmacht Panzergrenadier vibe going on.

I don't think it's a real one, as that gullwing down to the cockpit doesn't seem fitting of biplane design. Plus one of the reply tweets points out that the bomber gunners seem to be firing a gun of which only one was ever made though it was popularized by inclusion in Battlefield 1.

Some of the biplanes utilized the gull wing design, for instance Soviet I-153 and early versions of I-15. The bomber in the picture is likely fictional, although it seems to take design cues from WW1 planes (e.g. Gotha G.III / Gotha G.IV, which, notably, also used the "pusher" propellers).

I forgot to include the word "bomber," sorry. Heavy biplane designs pretty much stuck to straight wings, one attached to the fuselage and one either over or under it.
