The Recon in Battlefield 3 is the sniper class — well suited for long range combat with an assortment of sniper rifles, both bolt action and semi automatic ones. But that doesn’t mean the recon class is limited ot long range in battlefield 3, as the recon can use a variety of weapons, such as SMGs and shotguns for close quarter combat. In addition, the recon plays an important team role in Battlefield 3, where recons can set up a spawn point, motion sensor, and more. The recon starts out with two main sniper rifles: the MK11 for the US, and the SVD for the Russians.
While the recon is best suited at long ranges with a sniper rifle, it doesn’t mean it’s limited to that role. You can equip a semi automatic sniper rifle with less powerful scope (like a 4X), which would make you very useful at medium and close ranges. Furthermore, you can help your squad by placing a mobile spawn point close to the action, and you can deploy a motion sensor that detects nearby enemies.
