One of rap's most coveted crews is G-Unit. When 50 Cent, Lloyd Banks, Young Buck and Tony Yayo reunited onstage at Hot 97's Summer Jam this year, they helped squash the notion that hip-hop is dead. Fans felt like it was 2003 all over again (remember 'Stunt 101'?)

With their debut album, 'Beg for Mercy,' certified 2x platinum, it's obvious the G-Unit brand still stands strong despite the inner turmoil the group has experienced over the years. From 50 beefing with Young Buck to his war with Game, a reunion between the former members seemed like it would never happen. But luckily, 'TOS (Terminate On Sight)' wasn't the last project we'd hear from the group. 'The Beauty of Independence' EP, their first official release in six years, is out now and a full-length project is on the way.

Now that the G-Unit soldiers -- including newcomer Kidd Kidd -- are in the trenches once more, we take a look back at their storied career. Are you up to speed on all things in the Unit? Find out interesting facts like the rapper that prevented 50 Cent from being on a Jennifer Lopez song and how Lloyd Banks' sophomore album really got leaked to the public.
