If the original idea was that he means we should develop a more advanced and better trained force, then Im all for it. The idea of training to stop casualties and improve effectiveness has been around since the dawn of armies.
As for using better, newer, and/or different gear, sure, why not? However, the idea of using a "Special Tank Force" or other formation like that raises the question about how they'd be used and what role the remaining units would take in world affairs.
So basically, the idea of developing a "delta force" of tanks, fighter jets and artillery is the wrong application of the right idea I think. SFs currently is used to perform special tasks that typically require stealth infiltration in small groups. Perhaps a small tank team, like 6-12 tanks, trained specifically to break off from a larger group in secret to strike targets that are too large for infantry SF teams is a good idea, but elite fighter jets doesn't seem like an idea with a purpose backing it.
You want "elite" units, you put the absolute best of the best together. Although, that leaves the worst guys together which lowers the effectiveness of those units, so it's a dangerous tradeoff.
