2 man crew is a complete NO GO.
Cue the Rumsfelds of the world telling me that because of advances in technology there is no need for a 3 or 4 or 5 man crew on the rapidly changing modern battlefield where we just need more MRAPs and Strykers.
First, maintenance. Who's gonna do that? God help you if you throw track or something like that.
Second, I assume that there is only 1 gunner's station and only 1 driver's hatch. So... if something happens to either crewman, then you can't do at least one of the 3 things you're supposed to do as a Tanker - Move, Shoot, Communicate.
Now, let's say that you can use some sort of secure network to operate the turret remotely, your now putting your combat power on the ground at the mercy of the network crashing or getting hacked Iranian drone style. Wouldn't that suck? San Diego PD wouldn't be able to stop a runaway hacked Tank, not that they stopped the runaway M60 anyway.
There are other things that remain to be seen about how far the gun can depress and if the turret can traverse 360 degrees.
Another interesting thing I read in either a CNN or BBC report is that Russia plans to field something like 2200 of these by the year 2020.
I wonder what the US future Tank development plans look like. And I wonder what the Chinese plans look like too.
