Left to some of these "visionary" people in the military, even cargo transport won't suffice.
They'll want a Tank with Wings, to fly itself anywhere.
Doubt we'll see another Persian Gulf War tank battle in the future.
So why design a weapon that'll be obsolete, or have limited use.
There has to be a ceiling put on military spending in this country.
The cost to design/produce/maintain these weapons are becoming stratospheric.
