US Army supreme commander forgot to salute a Marine who gave her honor at the scale of a helicopter. Perhaps concerned about the event was to attend Barack Obama passed without even a soldier to take a look. As soon as he boarded the helicopter, the leader of the White House has realized the blunder and came down to greet him.It is not the first time Obama upsets the Marines. Last week, President and put the two soldiers to take their umbrellas for him and Prime Minister of Turkey, during a press conference. Marines rules prohibit them into the shadows when in uniform.
