'Close Quarters' will focus on infantry-only gameplay, with enclosed maps that are designed to take advantage of the game's destructible environments.
It will also add new weapons, assignments and unique dog tags that are usable in the main game.
'Armored Kill' will look at vehicular combat, offering new playable tanks, ATVs, mobile artillery and what's teased as the biggest map in Battlefield history.
Details of the fourth Battlefield 3 expansion, 'End Game' will be revealed in due course.

"Instead of delivering piecemeal map packs, we're giving players a completely new experience with every themed expansion pack to keep the action fresh," said executive producer Patrick Bach.
"Our expansions are designed to excite our large and active fanbase while attracting new recruits with gameplay that is dynamic and unpredictable every time."
'Close Quarters' will release in June, followed by 'Armored Kill' in the autumn and 'Close Kill' towards the end of the year.
The shooter's first expansion, 'Back to Karkand', was released in December.
Battlefield 3 has become EA's fastest-selling release ever with over 12 million units sold worldwide.
