It's also useless because the T-25 turret IIRC had a loader, and more than enough space to load the shells manually, and those shells are light and small enough to not need loading assistance. Even with a loader, sustained reload time will be shorter than the time required to engage a target (including re-aiming at the same target after a shot). The autoloader doesn't seem to have been ever exploited to reduce turret size.Seems like something that would have been ditched pretty quickly to put more tanks in the field faster.
I'm frankly impressed the Czechs even bothered with this, I can understand that in their Pz 38 (LT Vz. 38) modernisations because they had a two-man small turret with 47 or 57mm guns, but in the T-25?
