Two weeks ago, America's final combat brigade in Iraq -- the Army's Fourth Stryker Brigade -- journeyed home in the pre-dawn darkness. Thousands of soldiers and hundreds of vehicles made the trip from Baghdad, the last of them passing into Kuwait in the early morning hours. Over seven years before, American troops and coalition partners had fought their way across similar highways, but this time no shots were fired. It was just a convoy of brave Americans, making their way home.
