Military intelligence rakes in a lot of very questionable information. Like these new German tanks, for example.
This one is just a barrel of laughs. There seems to be some confusion over the Maus and its proposed 150 mm gun turret, a new Tiger turret to fit a 105 mm gun (the gun would need a whole extra loader, so a new turret is understandable) and... a something. I honestly have no idea how this heap of armament was supposed to be arranged. It's a shame the report didn't include at least a doodle.
