Lt. Col. John Nagl (US Army, ret.) tells the story of Jonathan Hopkins, a former student of Nagl's who was booted from the Army for being gay:
Jonathan is the third combat veteran I personally know who has left the Army under the terms of DADT. Collectively, they represent almost a decade of combat experience, a big handful of Purple Hearts and Bronze Stars, service as aide-de-camps to general officers and as platoon leaders and company commanders in combat, and the investment of millions of dollars in taxpayer funds. They have offered blood, sweat, and tears in defense of a nation that discriminates against them for no good reason.
This policy must end.
