There wasn't a doubt in my mind that he was a spartan 1 once halo 2 started, he was just kicking to much butt... especially for looking 55(that's how old he seemed to me) the only thing that seriously bothers me is the level of technology- 500 years in the future we have augmented superhumans, AI constructs, and gigabit networks with terminals running SFTP with CLI... no god forbid they be more advanced than todays current computer user....
