The plane in the pick is not a B-25B, but instead a B-25J with the solid strafer nose (or perhaps the Navy version of the same thing, which they called a PBJ). It's missing its upper turret, which was where the white dot is just behind the cockpit.
The B model as used by Doolittle et al didn't have waist guns or a tail gun. Instead, the upper turret was back in the waist area, and there was a retractable ball turret below. But the Doolittle Raiders removed the ball turret and installed an extra fuel tank there. It did not have a tailhook, either, as it was never intended to land back on the CV.
I really want a B-25 in the game, and the B model would be cool. What I really want, however, is the D, which saw all the important action in 42-43. I especially want the strafer version with 4x50s in the painted-over glass nose, 4x.50s on the sides, a field-installed tail gun without the raised gunner position, and field-installed .30s in the small waist windows. Or perhaps a very late D, with the same nose, a single tail gun in a raised position with better field of fire, and 2x50s in J-type waist windows.
The reason I want a D instead of a J is that the D was faster and could fly on 1 engine. The Js like in the pic above couldn't maintain alt on 1 engine, which led to many unnecessary losses.
Back in AW, we had a glass-nosed J with 6x.50s fixed forward, plus a swivel gun for the bombardier. That was a good plane for furballing with all the gunner positions filled

. In WB, we had the H, which was like a J except it had 4x.50s and 1x75mm howitzer in the nose. In real life, however, the big gun was found rather ineffective, and the lack of a copilot somewhat risky, so they often replaced the 75mm with 2x.50s.
