  Charles has held many titles and honorary military positions throughout the Commonwealth, is sovereign of many orders in his own countries and has received honours and awards from around the world. In each of his realms, he has a distinct title that follows a similar formula: King of Saint Lucia and of His other Realms and Territories in Saint Lucia, King of Australia and His other Realms and Territories in Australia, etc. In the Isle of Man, which is a Crown Dependency rather than a separate realm, he is known as Lord of Mann. Charles is also styled Defender of the Faith.
  
  There had been speculation throughout Elizabeth II's reign as to what regnal name Charles would choose upon his accession; instead of Charles III, he could have chosen to reign as George VII or used one of his other given names. It was reported that he might use George in honour of his grandfather George VI and to avoid associations with previous controversial kings named Charles. Charles's office asserted in 2005 that no decision had yet been made. Speculation continued for a few hours following his mother's death, until Liz Truss announced and Clarence House confirmed that Charles had chosen the regnal name Charles III.
  
  Charles, who left active military service in 1976, was awarded the highest rank in all three armed services in 2012 by his mother: Admiral of the Fleet, Field Marshal, and Marshal of the Royal Air Force.
