Anything that is mechanical can break, with that said Russia has been using autoloaders for over 50 years, every tank from the T-64 to the Armata has auto loaders, Russians are all about reliability so if the auto loader would have issues they would have abandoned the design decades ago but they did not which says a lot. Many other tanks including new "western" tanks have also switched over to autoloaders. The people bashing autoloaders are obviously jealous, they are getting defensive and insecure; in their mind Russia is supposed to be outdated and rusty and their engineering is supposed to be pathetic. So when the T-14, T-15, Boomerang, Kurganets 25, ect came out the same people had to find anything and everything to attack the T-14 on, no matter how silly, the worst thing is that many of the people are trolling but will pretend that they are not. The biggest arguments people have towards the T-14 is that tanks are a thing of the past and drones are the future (as if drones will stop entire armies fielding heavy tanks and having air superiority). The other argument is that the T-14 is just an Abrams "rip off" and of course the proverbial but...but...but...it's an auto loader therefor it will jam and we will just destroy it.
