Dr. Halsey was looking at a total of 150 canidates for the Spartan 2 program. He was the 117th of the total. Out of that 150, 75 including the Chief were selected for the training and all 75 canidates were only 6 years old because the doc felt that would be a good age to start learning properly. He's first name is John but his last name remains unknown. And Master Chief is his rank.
hope that helps
