In general, this incarnation of the Doctor was more physically daring than the previous two and was the first to confront an enemy physically if cornered (both of his previous incarnations nearly always attempted to dodge, flee or negotiate rather than attack). This often took the form of quick strikes, with the occasional joint lock or throw — usually enough to get himself and anyone accompanying him out of immediate danger, but usually not to the extent of a brawl, in keeping with the Doctor's non-violent nature. He only used his fighting skills if he had no alternative, and even then generally disarmed his opponents rather than knocking them unconscious. Indeed, his martial prowess was such that a single, sudden strike was usually enough to halt whatever threatened him, and at one point he reminded Captain Yates of UNIT (physically as well as verbally) that Yates would have a difficult time removing him from somewhere when he did not want to be removed ("The Mind of Evil").
