Just watched the wreath-laying ceremony at the Tomb of the Unknowns in DeeCee.
POTUS Barack Obama paid his respects, and in doing so marched in perfect step and pace to the center of the memorial, laid the wreath, executed a proper civilian salute during our National Anthem, and later, during Taps. He left his position, using military facing movements.
This all required practice, and I commend President Obama for taking the time to practice. In the past, he has not shown this level of dedication to the military minutia which is important for the respect it conveys.
