Re: Outdated?
You are about a hundred years early on that. Prior to WWI, the Smart People decided that there would never be another crossing of the T. The T was crossed during both WWI and WWII.
Likewise, the MBT is not going to go away anytime soon. Certainly, their utility in a US-China war will likely be limited, but we've got a long ways to go before the tech reaches the point that even the bulk of regional conflicts will catch up. Moreover, the anti-anti-tank technology is ALSO advancing rapidly.
