Brendon Huor and Nate Hitpas are members of the LBP Stunts team of Chicago. We’re guessing they’re buddies, since they’re teammates and all, but this amazing fight scene between the two stuntmen has us thinking otherwise.

The boys brawl in the dirt, using some convincing Korean martial arts techniques. The clip starts off on a somber note, but things get bloody and bruise-y fast.

With such incredible acuity, it’s hard not to think some of these blows were real.
