Matt Best, the veteran Army Ranger and the man behind the hilarious YouTube Channel MBest11x is at it again with a new rap battle video — Marine Special Operations Command vs. Green Berets.

Best has emerged among the most prominent voices in the Special Operations community, and he’s definitely the funniest. His previous rap battle video, SEALs vs. Rangers, was a huge hit.

In this one, he went all out, even renting a helicopter.

Here are some of the best lines:

Green Beret to MARSOC: “All you are is Force Recon, changed your name for recognition.”

MARSOC to Green Beret: “If being a Green Beret is so hard, how come you can have groups in the National Guard?”

Give it a listen below. (Warning, strong language):
