Our next Operations challenge is underway and will be running from 03:30 PST (11:30 UTC) on January 21, 2013 to 03:00 PST (11:00 UTC) on January 25, 2013. You can use this fancy Time Zone Converter to discover what time the event will start in your neck of the woods.
Now for the details. As you may have been able to decipher from the title of this post, this event will be centered around the Defender medal, each time you obtain this medal you'll be rewarded with an extra 1,250XP for the match!
Reduce the number of enemy capture points of a friendly base by 70 or more. If two or more players have reduced an equal amount of capture points, the achievement is granted to the player who has earned more XP in the battle (including additional XP provided to Premium Account users).
Now for the best part: this Operations event is repeatable. That means you'll get this reward every time you meet the above criteria as long as the event is still active.
