I just looked at the basic-electricity one

Much of this I learned before and in High School.

I would bet a large amount of money that 99.999 percent of High school grads in the usa today have never learned any of this.

I would also bet they can name more genders than I can

[PROCON]

Army tech manuals are written for soldiers who have never learned the subject before, they do start at the basics.

I took the basic electricity and all the other advance courses, I was an avionics tech/aircraft electrician.
