Support

The Support  kit is a playable kit in many installments in the Battlefield Series. Its main role is to resupply friendly teammates and provide heavy suppressive fire for the team. The Support kit acts as a Medic and Engineer in Battlefield: Bad Company.

Overview
Support forces, unlike Assault and Engineer, have a defensive role. The Support's lack of mobility and accuracy is compensated with extreme firepower, using belt-fed Light Machine Guns, useful for suppressive fire, making the opposing forces think twice before subjecting himself to death while friendly forces move forward or when a friendly base is under attack. They also carry a handgun, useful for close quarters combat or when the LMG's magazine/box is out of ammunition. Besides the defensive role, Support is also tasked to keep friendlies resupplied, with deployable ammo boxes that automatically regenerate ammunition to any players nearby.

Battlefield 3
The Support returns in Battlefield 3. The class is more akin to Refractor-era Support kits, as they are equipped with Ammunition Boxes, used to replenish ammunition for teammates. With the introduction of the Suppression system, the Support class takes on an additional role of being a key presence by effectively shaping the battlefield by diverting and dispatching opposing forces. Combined with their weapons having a higher ammo capacity, the Support class further highlights its effectiveness by having the ability to deploy the Bipod attachment on their weapons (equipped by default) at strategic positions and choke points. This allows the player to cover an area by fire whilst maintaining accuracy. In conjunction with gadgets such as the M18A1 Claymore and M224 Mortar, the Support class is able to adapt to urban and open combat. Support players are also able take on an anti-armor role with C4, a feature absent from previous Battlefield titles.

Battlefield 4
The Support kit reappears in Battlefield 4 and is almost identical to that of Battlefield 3. It does, however, have different gadgets and can now utilize a new grenade launcher, the XM25. The Support still retains use of both C4, Claymores and the M224 Mortar, however, the Mortar has been redesigned to be remote-controlled instead of being hand-operated.

Trivia
BF4= A persistent bug may occur whereas the player cannot spawn as Support. If attempted, the game will crash upon spawn. Prolonged inactivity from the class seems to solve this bug. BF3= BF:BC=
