Possibly South Korea or India

These were in my Dad personnel box they look like Air Reconnaissance photos as you all know .He was in India during 1942-45 and S Korea in the 50s, these are unmarked and this box has mixed photos, Also here is a letter to him 1994 before he died 1995. He finally joined a group of veterans, Air Commandos association this letter is from the president of the group writing about his surprise. When he saw my Dad flew with the famous flight of the L-5S from Kalaikunda India to China in 1945. He was given the Distinguish Cross Medal after this. Bottom guys from the left the 3 guys looking away. Not to the photographer ,
