Dytor was born in Cardiff. He served with distinction in the Falklands War, being decorated with the Military Cross for gallantry in action during the Battle of Two Sisters. On the night of 11/12 June 1982, 45 Commando Royal Marines launched a silent night attack against strongly held enemy positions on the craggy hill feature of Two Sisters, ten kilometres to the west of Port Stanley on the island of East Falkland. Initially they progressed onto Two Sisters undetected. However, a fierce fight ensued once they were detected. At the height of the fighting Dytor and his troop were pinned down by enemy fire, he encouraged his troop forward and personally led the assault on a strong enemy machine gun position.
