Battlefield 3 Classes Detailed

DICE has passed out some information regarding Battlefield 3's "classes" you will be able to choose from; Assault, Engineer, Recon, and Support.

Assault classes will assume the responsibility once held by the Medic class. This class will come with medkits and defibrillators to assist those wounded players.

Engineers will be able to repair damaged equipment and damaged vehicles, the class will also be more adept to destroying mechanical things as well. This class will be equipped with the Carbine class of weapons.

The Recon class (some of you may recognize them as the Sniper class) will make use of new gadgets and scouting equipment. DICE wanted to make the Recon class more of a team-oriented class instead of just the "shooter on the roof" type.

The Support class will be tasked with using suppressive fire as well as carry light machine guns. This class will also be able to utilize heavy artillery.
“Support has always been about heavy infantry firepower from his LMG,” said Alan Kertz, senior multiplayer designer at DICE. “It’s a role that we’ve wanted to feel different than Assault’s running and gunning.”
Two new features will be included with the Support class; Bipods and Suppressive Fire.

Suppressive Fire will be an in-game effect that only the Support class will see that will blur the screen in real time as bullets whiz by. Bipods provide “substantial increase in stability while laying down a base of fire,” and can be utilized just about anywhere. The Bipods provide better accuracy and reduce recoil.
“Supported shooting with Bipods and Suppressive Fire finally allows us to achieve an obvious difference between Assault and Support, since the heavy LMGs are not terribly mobile,” explained Kertz. “When deployed with a Bipod, they become an incredibly powerful force. Suppressive Fire forces the enemy to keep their head down and lets the Support gunner pin his enemies in place so teammates can flank.”
Battlefield 3 is out in October for the PS3, 360, and PC.
