Any space marine can get murked by an ordinary guardsman with a plasma rifle. A delta psyker is more than a match for any space marine. An ogryn is actually stronger than a space marine, just infinitely less intelligent. Our zealot actually has Sororitas-levels of faith that can manifest a miracle (Chorus of Spiritual Fortitude). An Arbites has an approximate amount of training as a Astartes and could easily take one down with prep time and the right weapons. A team of seasoned Inquisitorial Acolytes would be a good match for any lone Space Marine (wearing a helmet) in a fight.
