2. Play your class
A pivotal part in Battlefield 3, like its predecessors, are the different classes. Each class is meant to do something specific and it would be wise to play your class the way it was meant to be played. The four classes: Assault, Recon, Support, and Engineer are all capable of shooting the other team, but they all have different jobs that support the team in other ways. For example, the Assault class, which has also taken on the role of Medic, are on the front lines and there to assist other players who might have been downed by resuscitating them. If someone goes down or requests health, use your class kit. You aid the team and you get points, win-win. Keeping players up or reviving them goes a long way to making your respawn tickets count.
The same could be said with the Support class, who can dish out ammo like it was going out of style. Support classes are capable of providing an unlimited amount of ammo and grenades to teammates. In addition to providing ammo, Support is also capable of utilizing the LMG to provide large amounts of suppressive fire, a new feature to the game which awards players for doing so and at the same time, negatively impacts the opposing player under fire. Remember, it’s about the team victory, not being greedy with K/D.
Throughout each map, you will notice several crates or containers dotting certain areas, these are choke points. Utilizing the LMG’s bi-pod (going prone or setting up near a container), laying out ammo, and coordinating with teammates can result in effectively holding a position indefinitely.
If you decide to play an Engineer, your primary objectives involve friendly vehicle upkeep and destruction of enemy vehicles. Any vehicle in Battlefield 3 can make the difference between victory and loss in any skirmish, so keeping them functioning is very important. Stay close to vehicles and be mindful of when they get destroyed. Vehicles do respawn, but it takes time. Why bother waiting when you can repair? Also, killing enemy with a blowtorch is just as fun as killing them with a defibrillator.
One note for Engineers, do not run around with your flashlight on all the time when near teammates. It blinds everyone, not just enemies. Not only that, it will also give away your position pretty easily in close quarter scenarios. If you want to utilize if properly, use it as a defensive measure to blind an enemy once you get the drop on him.
Lastly, the Recon class is just that, recon. Whether you opt to snipe or run with a SMG/PDW, getting in and laying down a Radio Beacon to aid closer team spawns, utilizing motion sensors near objectives or choke points, or using the laser designator to tag enemy armor is all important. Stay mobile and stay alive, Recon can usually serve as a good class to spawn on because of their relative closeness, provided they don’t get killed because someone saw their scope glint.
Each class is geared to excel at certain tasks, play each one and figure out what you like the best. Just remember, when you play in squads, it’s not entirely beneficial to have nothing but Recon. Just saying.
