HOOAH! These US military veterans now have big roles on Wall Street

The American military has been breeding the US' top leaders since the day the Declaration of Independence was signed.

There are a lot of other Wall Street hot-shots, too. Big name banks like JPMorgan and Bank of America have launched ambitious initiatives to bring the military's finest to the forefront of financial services.
