Martok is portrayed as an excellent judge of character, caring deeply about those under his command. This, in turn, earned him great respect among fellow Klingons, since while they have a love for battle and conquest, they also have a very low opinion of those who wantonly throw soldiers into battle with little regard for their safety or well-being. These traits, along with his courage and leadership skills, would serve him well in the Dominion War, during which he fought in several battles, including the battle to retake Deep Space Nine, and the First and Second Battle of Chin'toka. Despite his humble background, or perhaps because of it, Martok would become extremely popular among other Klingon warriors and the civilian population, because he climbed his way up the ranks honorably, though Martok himself repeatedly stated he had no interest in politics. Eventually, he was made Supreme Commander of the Ninth Fleet, a position he initially resented because of the amount of paperwork involved. Like most Klingons, Martok had a disdain for Ferengi, which manifested itself in several refusals to even acknowledge Nog, who at the time was a Starfleet Cadet. It isn't until Nog stands up to Martok and directly challenges him that Martok begins to display a grudging respect for the young Ferengi (episodes "Soldiers of the Empire", "").
