That's the point. There aren't any numbers because the military does not allow oversight.

Look at this shit about the Abrams Tank and consider that armor is a small part of our military

The M1 Abrams tank has a fuel economy of 0.6 miles per gallon. Variants of the Abrams tank weigh between 60 and 70 tons and are powered by a 1,500-horsepower turbine engine. An armored division of the Army can use as much as 600,000 gallons of fuel a day. A cargo vehicle like the M-1070 semi-trailer (designed to haul tanks) gets approximately 1.2 mpg. The M1 Abrams tank consumes about 60 gallons per hour while traveling long distances and can travel approximately 250-300 miles on a single gas tank.

This doesn't even take into account active devastation caused by munitions testing
