Mixed Martial Arts is effective for hand to hand one-on-one combat.
List of some of my favorite fighters/warriors:
WEC Bantamweight Champion. He is one of the pound-for-pound greatest fighters and most complete fighters. Has some of the most fluid ju-jitsu and technical striking in MMA.
Heavyweight Affliction Champion from Russia. Consensus the best fighter in the world.
Anderson The Spider Silva
Middleweight UFC Champion From Brazil. The pound-for-pound best fighter in the world.
Mauricio Shogun Rua
Light Heavy Weight (Considered one of the top Light Heavy Weights in the world)
The so-called "face of women's MMA," is one of the most talented woman mixed martial artists. Women's MMA doesn't get as much attention as men fighters, but they are just as hard working and fights are usually more technical and exciting. She's definitely one of my favorite fighters.
The Diaz Brothers
From Stockton Califas, both train in Gracie Ju Jitsu and boxing. Hood as fuck, and don't give a fuck.

Light Weight/Welterweight Fighter from Hawai'i, UFC Lightweight Champion. Considered to be one of the greatest fighters of all time.
George Rush St Pierre
Welterweight UFC Champion from Montreal. Considered to be the most complete fighter.
Lightweight fighter, one of the best young Lightweights out there and is getting better, and he is definitely down for la raza.

Anarchist Mixed Martial Artist
Quinton Rampage Jackson
Lightweight fighter from Japan
