@Viktor Jav
I am phoning this one in.
Okay no I am not the Chieftain.
But he makes two critical points here. That I absolutely agree with, and seem to go with your thinking.
- Speed is more a factor of the targeting than the loader but the Automaker loader is more consistent.
- Automatic loaders are complex machines that are dropped into complex machines loosing a man in the tank doesn’t necessarily mean loosing a extra man.
So lest address your points. First the BOG/Assistant Driver/Radioman the reason they went away was because they were absolutely unnecessary. The BOG position was Bow gunner basically he manned a firing port and his weapon was only aim able by turning the tank. Because he was in the hull his actual range of view was limited and as tanks moved beyond 90mm guns his usefulness vs extra ammo was deemed more to ammo.
Assistant driver is basically the same position in some old tanks with the same problem.
Radioman again same guy different job but as the Second World War closed the radios were more easily operated by the TC or loader because of improvements and moved to the turret. The larger shells dominate more space then the small caliber ww2 versions.
Optics wise the loader has the same vision blocks as the others where he shines as an extra pair of eyes is in non combat where he and the TC can stick there heads out for an unobstructed view. The gunner position is made for servicing the target the TC for finding it as such the gunner has a soda straw view the TC has a 360 view. Add a loader and you have two 360s even with modern optics that’s hard to match. But once the fighting starts he’s down below serving the gun. Even if you have an abrams with a extra turret MG he’s not using it if the main gun is in the fight.
Not vs an automatic loader the biggest nice point is that the loader can be doing remedial action if the gun doesn’t go Boom well the gunner and TC keep her in the fight.
