The 2002 war game known as the Millennium Challenge exposed gaps in the critical thinking training of the US military. In fact, it has been 100 years since the last comprehensive review of its education system. In the meantime, “conventional warfare” has evolved into adversaries and insurgencies without a discernible front line. The U.S. Navy is now conducting a major study that’s expected to lead to a radical shift in the education of its personnel. The Navy will almost certainly recommend doing far more to emphasize critical thinking skills in its training and development programs.
