Aircraft in the background are Me110s, and the Luftwaffe ground crew man is holding what appears to be a Soviet MG.
I'm not that familiar with Russian aircraft, but I think the "wreckage" may be Russian, and no doubt others here can identify it.
I agree with Airframes. The machine gun is the soviet 7,62 mm SzKAS. It is the variant used for a gun turret in 1940. So it may suggest a soviet plane with the gunner station ( mostly the top rear one ) powered by the inline engine. IMHO it could be the Tupolev SB-2M-103.
My first thought was that it may be a pile of wreckage containing at least 2 aircraft. Prop and spinner on the right looks like an inline engine but the exhaust details at left suggest radial.
With the Liquid Cooled engines, smooth cowling and the exhaust pipes exiting the top side of the leading edge of the wing, I think it is a Arkhangelsky Ar-2 dive bomber.
