If you're like us, you watched the new trailer for 'G.I. Joe: Retaliation,' immediately noticed that awesome music, and now you're wondering what song it is. Good news! We've got the answer.

The new trailer for 'G.I. Joe Retaliation' is pretty great, and we're so excited to see the film when it hits theaters in March. With Bruce Willis, Dwayne Johnson, Channing Tatum, Adrianne Palicki, and all that crazy action -- what's not to be excited about?!

But the biggest takeaway from the new trailer was that bad-ass song they used, and we're sure you want to know what it is. The song is called "Little Weapon," and it's performed by Lupe Fiasco featuring Bishop G and Nikki Jean. We think it's the perfect music for the trailer, especially with the incorporated military-style drum taps, which just get us in the mood to kick some ass... or let Channing Tatum kick some ass for us.
