[Jukebox-list] A better understanding

[Karl]

It is well written for sure. The military has a long history of teaching
young people in about 3 or 4 months to repair some of the world's most
advanced systems. without different levels of maintenance and easy to follow
diagnosis and repair procedures, that would be impossible. Consider that
most of those young people have never held a screwdriver in their hand and 6
months later are repairing M1 Battle tanks. The manuals are so well written
that I never went to any school to repair anything for the army but repaired
everything from small arms to big arms for 20 years.....LOL. I'd say that
makes me a genius if there weren't about 100,000 18 year olds doing the same
thing ;)
