Here from a man whose job it was to keep US military trucks rolling..
https://www.youtube.com/watch?v=iaz8RrsRKyc Seems like a two fold problem, neglect and corruption..
First neglect..Perhaps the troops are going by the old USSR maxim..
"We pretend to work, and they pretend to pay us!"
Corruption..If the records show that the tires purchased were good for 5 years and 90,000 miles, but with politicians and procurment officials each taking their slices, until what was put on the truck was 2 year 40,000 mile tires...that could cause a problem.
However, we may have no room to gloat, considering all the corruption we have seen uncovered, concerning $50K per month job with a foreign gas company, a Russian mayor's wife and the Chinese giving our politician's kids billions to play with! Even $75K each for some junkie's finger paintings..
