Yes the B-25's up to the C/D model had a ventral turret with two .50's in it. The problem was the turret was too small to carry a crew member so the turret was controlled remotely by a gunner kneeling on the bottom of the aircraft looking through a periscope. I've been told the British had more luck with it than the Americans but I haven't read any RAF accounts. The stories I've read from US crew members seem that the setup was nearly universally hated, difficult to operate and track a target and usually just succeeded in making the gunner nauseous with vertigo, in many cases they were removed in the field.
A quote from Harold Maul who served with the 5th Air Force in the SW Pacific had the following to say.
A part of that quote points out the main difference between RL WWII japanese b25 attack methods, and AH's attack method. where he says they werent getting attacks under the bomber.
In AH. Whenever you up a C. Most people will simply Hide under it, out of range of the top turret. And you can pull up to an angle where you can get a good burst into the plane without the top turret ever being able to reach you.
Sure you can tilt the bomber, but that still isent very effective.
I think the ball turret would be very successful in AH. It DID see action on combat b25s and was not a field mod. so it Does deserve to be added and modeled. whether used or not.
