The medal is normally awarded by the President of the United States in the name of the U.S. Congress. Because the medal is presented ``in the name of Congress'', it is often referred to informally as the ``Congressional Medal of Honor''. However, the official name of the current award is ``Medal of Honor'', as it began with the U.S. Army's version. Within United States Code the medal is referred to as the ``Medal of Honor'', and less frequently as ``Congressional Medal of Honor''. U.S. awards, including the Medal of Honor, do not have post-nominal titles, and while there is no official abbreviation, the most common abbreviations are ``MOH'' and ``MH''.
