Characters with no fleshed out backstory

Community Halo Universe

Hey y’all. I was wondering if all you lore keepers might help a brother out. I’m trying to find a character in the Halo universe that meets 4 qualities:

  • Is a member of the UNSC. (branch irrelevant) - Is still alive as of Halo 5 ending. - Does not have a fleshed out backstory beyond their career in the UNSC or what is known about them in official canon. - Preferably would have been young, around 14-18 during Humanities initial contact with the Covenant

Most of the Spartan-IIs with limited information would fall under these parameters. I mean those that are not listed as dead or MIA that is. Like Gray Team. They are members of the UNSC, still alive as far as we know, are pretty limited as far as lore goes (two books total), and were around 14-18 when the war began.
