I agree. Left to their own devices, the lighter-leaner-more lethal crowd will downsize and outsource our military till well have one division equiped with one tank, one aircraft, and one battleship.
The tank will have wheels instead of tracks, it will need "cow catcher" add on slats to be able to ward off 50 year old RPGs. The aircraft will not be able to talk to the ground troops and will have a single air to air missile for self defense. The battleship will be a destroyer escort in all but name.
