Someone looking like my grandfather

Elalamein

Recently I saw a TV show about World War 2 and I noticed someone whose resemblance with my grandfather is stunning. According to the narrator, he was returning from Egypt, where he had fought the Nazis as a soldier of the Greek Army and so had one of my grandfathers, who also got wounded in El Alamein!
 
My mother said to me that he is not the same person, but I find too many similarities between the two and that's why I'm posting the photograph here.
