I've probably mentionned this before, but I think one of my favorite example of a Warlord to point to is from this little show called
Class of the Titans. Class of the Titans is about seven descendant of Greek mythological heroes who are recruited by the Greek Pantheon to stop Cronus who escaped from Tartarus (something about a prophesy). Each of them has a supernatural gift from their ancestor.
Herry gets the super strength of Heracles
Atlanta gets the super speed of Atalanta
Thessa gets the instinct of Theseus, which manifest as precognitive psychic powers
Odie gets the intellect of Odysseus and is a total Artificer
Archie is a descendant of Achilles who has all the natural aptitude of a warrior that his ancestor had (and he never gets sick)
I'll skip over Neil for a moment and go straight to Jay, who is the descendant of Jason.
Jay's gift is 'leadership'. He's a competant warrior of his own, but he doesn't any of the near superhuman gift of the others when it comes to facing monsters sent by Cronus. He's a normal human... But his skill at leadership become incredibly obvious whenever he's being kept from the others. Without him, they stop getting along as easily (they didn't know each other before this whole thing), they can't execute their plans well, they get fooled by the bad guys... It's a total mess. You take any of the heavy bruiser, the precog or the super genius away and they barely lose a fraction of their abilities,
but take Jay away and it's like they lost 50% of their power.
