WASHINGTON (November 11, 2012)--President Barack Obama paid tribute Sunday at a Veterans Day ceremony at Arlington Memorial Cemetery to "the heroes over the generations who have served this country of ours with distinction."

He said the wreath he laid at Tomb of the Unknowns at Arlington National Cemetery is intended to "remember every service member who has ever worn our nation's uniform."

Mr. Obama said in a speech at the cemetery's Memorial Amphitheater that America will never forget the sacrifice made by its veterans and their families.

He also said "no ceremony or parade, no hug or handshake is enough to truly honor that service."

Mr. Obama said the country must commit every day "to serving you as well as you've served us."
