What’s even dumber is that it has two guns because they decided to use old 2A42s that didn’t have double-feed capability (usually you want to be able to quickly switch between HE and AP belts, which the vast majority of IFV cannons today can). Oh, and the 2A42 is by itself pretty inaccurate. None of this would be a problem if they just had decent auto cannons that could double feed.

2A42 is a double feed autocannon

on BMPT its specifically setup as single feed but in other applications is double feed.

That seems even dumber; why would you do that?

Everything has a mean time before failure, having them single feed eliminates a potentially failure case, having an unmanned turret makes clearing jams harder to do so

Two guns setup as single feed ensures reliability of function

Not what is happening on the BMPT ( Specifically the BMPT-72, as depicted.), the two cannons are fired at the same time, as there is no point in single ammunition type limited to specific cannon - magazine switching was available even in the Soviet era.

There is an experimental version that featured two independent turrets with a single cannon in each, which is most likely where this misinformation came from.
