I found further info on Kamolov on artist's twitter. Translation:
An honest fellow from the small village of Georgia with a passionate and righteous personality , Kamolov is the youngest son out of five children. He has two older brothers, one older sister, and one younger sister. During the war his family moved to Kyiv (Ukraine's capital) as it possessed vastly stronger defenses than nearby settlements. For a time the city suffered from resource shortages and his entire family was forced to participate in city conservation work just to get by. Kamolov was unable to contribute however due to his thin and frail stature, and could only stay home and look after his younger sibling. After the war ended, Kamolov managed to continue schooling with the economic support of his family and was determined to better himself. The result was a massive height increase from 150cm to 187cm between age 13 and 16. (The artist seemed to only include this to emphasize that Kamolov is indeed a young man)

Maybe he'll look his age once we get that moustache off him, sacrilegious as it may be =3
Jokes aside, the latest chapter has established that Area S09 has more than one base: Gentiane's 794, Shi Jun (or Sekigun? Spectacles-kun either way)'s 601 and Kamlov's 737. This means S09 covers a bigger area than what may be hinted in the game.
And yeah, Kamlov is really 23 years old (important!)
