Serhii's brother Volodymyr Doroshenko is a fighter of Ukrainian Volunteer Army. He recalls Rubanchykov:
"Serhii was never for himself. When my son was born and we had some difficulties, he did his best to help is. Probably, he loved my son, his nephew, the most. He spent more time with my son than I did. Serhii would never complain and always stayed calm.".
