The prayer to Saint Michael mentioned in the story titled, "Incredible Miracle: U.S. Marine Saved by Saint Michael", seems to be this one:
Michael, Michael of the morning,
Fresh corps of Heaven adorning,
Keep me safe today,
And in time of temptation
Drive the devil away.
Angel of God Prayer
Angel of God, my Guardian dear,
To whom God's love commits me here,
Ever this day be at my side,
To light, to guard, to rule and guide.
