US can "beat" plenty of countries. The question, though, is, at what price.
Even in the Gulf War against Iraq, where the US also had a whole "Coalition" of Western and Arab countries on their side, they (the whole Coalition) still lost hundreds of men, dozens of tanks, etc: Gulf War - Wikipedia
That's against just Saddam's Iraq.
Against Russia and/or China (and those two likely WILL fight together, if push comes to shove)... US and West may well prevail. Expect to lose more than one entire aircraft carrier battle group of your Navy though. And many, many thousands of men on the ground. And that's in a purely conventional fight, without even talking about the nuclear weapons...
I'd be very interested to get a peek inside the T-14 crew compartment. Russian tanks have never been about crew comfort whereas American tanks put a premium on crew comfort and survive-ability. Reminds me of what the WW2 soviet tanker said about his M4 Sherman..
Q) It is considered noteworthy that the Sherman was very well appointed on the inside. Was this true? A) It was true. These are not just words! They were beautiful! For us then this was something. As they say now, "Euro-repair"! This was some kind of European picture! In the first place, it was painted beautifully. Secondly, the seats were comfortable, covered with some kind of remarkable special artificial leather. If a tank was knocked out or damaged, then if it was left unguarded literally for just several minutes the infantry would strip out all this upholstery. It made excellent boots! Simply beautiful!

re T-14's tc hatch opening upward, Loza also mentioned why thats a bad idea..
One more shortcoming of the Sherman was the construction of the driver's hatch. The hatch on the first shipment of Shermans was located in the roof of the hull and simply opened upward. Frequently the driver-mechanic opened it and raised his head in order to see better. There were several occasions when during the rotation of the turret the main gun struck this hatch and knocked it into the driver's head. We had this happen once or twice in my own unit. Later the Americans corrected this deficiency. Now the hatch rose up and simply moved to the side, like on modern tanks.
So yeah its weird that almost a century later the new T-14 would use a hatch that swings up.
