In 2014, it's easier than ever for fans of different pop stars to connect with each other. With the explosion of social media making it simpler than ever to find other fanatics of your favorite artist, "fan armies" have become a shorthand for singers' most dedicated followers, the ones who can't get enough of their most beloved artists and who get ample shout-outs in return. In this day and age, you haven't truly reached pop superstardom until you have a fan army -- from Britney's Spearleaders to Justin's Beliebers to the new-school armies like the Arianators and Mahomies, fan armies are constantly demonstrating their support in good and bad times for pop's brightest stars.

Only one question remains: which fan army is the strongest? Billboard.com hopes to answer that question with the Fan Army Face-Off, a bracket-style tournament in which various fan armies will square off to prove that they are unequivocally the loudest voices in the pop sphere. We've rounded up 32 of the most notable fan armies today, and through five rounds, we'll let the fans themselves determine which fan armies stride forward, or fall by the wayside. Vote now in Round 1 of the Fan Army Face-Off, and show your support for your favorite artist! Polls close July 11. (And click here for the full bracket, or scroll to the bottom.)
