Hristo,
It is my theory that the screen shots are:
An Ar234 wearing the skin of an Me262
&
An N1K2-J wearing the skin of a Hurricane MkIIc
I have never heard of an Me262 using RATOs and I know the Hurri IIc didn't have 400 rounds for its inner guns and 500 rounds for its outer guns, it has 90-91 rounds per gun.
Translation: Look a the pictures, but don't believe the ammo indicators.
