MTV.com posted up a short behind the scenes video for "Know Your Enemy". The video will premiere April 24 at 8 p.m. ET on MTV, MTV2, MTV Hits, VH1, The N and MTV Networks' HD channel, Palladia -- plus MTV and VH1's international channels -- in addition to MTV.com and VH1.com.

Apparently the video is US-only. Visit the forum to see if someone will be able to share the video on YouTube or something.

Only 3 more days till we get the single.

Update 9pm: GreenDay.com got a new design.
