Except the advantages of a slightly lower silhouette vs say a K2 or Leclerc mean you can no longer do anything if something goes kinda wrong with the autoloader or gun (the Leclerc style autoloader CAN be manually loaded very slowly) and an Abrams for example has a plain Jane telescopic sight as a backup oge the gunners main sight if necessary. That backup is unavailable on a robot turret. The UAE Army saw in Yemen that a random lucky hit to the gunners sight could make a Leclerc temporary useless as it doesn't have a backup oge the gunner.
The irony is that the T-14 is considerably taller than pretty much any Western MBT. Seriously, that thing is fucking huge, it's a rolling barn. While modern MBTs have the driver (the only hull crew) reclined and "cozy" (to use a The_Chieftain-ism), in the Armata all three crewmen seem to be sitting up a fair deal straighter and also side by side. So the hull is pretty tall to begin with. Add to it the remote MG station on the top and the damn thing is extra-tall. And with the crew sitting fully in front of the turret ring, with extra space behind them, the tank is also extra-long.
Seriously, if that thing weren't Russian it would be a goddamn best-seller in Texas. That's how unnecessarily large it is. The T-72 already looks small next to an Abrams, but it looks like a goddamn midget near a T-14.
Anyway, the concerns about the autoloader and sights are definitely valid, but my point wasn't that the T-14
as designed is a good tank. The apparent lack of
any turret armor on any of the models we've seen so far speaks to that. The point is that nothing about its design is technologically
unworkable. There are definitely tradeoffs, some of which we haven't been willing to make (hence why going up to the M1E3 instead of going with an unmanned turret like on the
actual tech demo Abrams X), but those can still be debated depending on what you want to do with the vehicle in terms of both doctrine and end-user capabilities. It's like gas turbine engines back in the 70s and 80s: there were plenty of jokes about how thirsty those engines were but we made the decision to accept the compromise of lower gas mileage for all the engine's upsides. (And then we proceeded to gradually improve said gas mileage but that's neither here nor there.)
Speaking of gas turbines, imagine a bizarro universe where LazerPig is a vatnik. How much time and cope do you think he'd spend on the M1's engine, talking about how it drinks a whole oilfield's worth of gas every hour, and how it's "way too powerful" for the vehicle because it usually has a governor installed? Because you know he'd latch on to that shit too.
