Army Col. Paul Yingling says he would rather teach kids than advise generals.
I'm a colonel in the U.S. Army, and next summer I will retire to teach high school social studies. My friends think I'm crazy, and they may have a point.
Colonel is the last rank before general's star, and it comes with significant perks. My pay is triple the national average teacher's salary. Military budgets have doubled over the past decade, while school districts have slashed funding, increased class size, cut programs and laid off teachers.
