Support action

A support action in the Battlefield series is any beneficial action given to a teammate.

Support actions are available in all Battlefield games, but were given greater emphasis in Battlefield 2 by awarding points for these efforts.

Players do not earn bonus points for performing these actions upon themselves or on empty vehicles.

Healing
Using a medkit to restore another player's health.

A healing point is typically awarded for every 50% of health restored.

Revive
Using a defibrillator to revive a downed player. Only one revive point can be earned for a particular player per life. If a revived player is wounded again, the same player does not earn another bonus point for another revive.

Repair
Using a wrench or repair tool to fix a vehicle, device, or strategic object belonging to the team.

For vehicles, another teammate must be occupying the vehicle in order to earn repair points. It is common courtesy for a player to enter a vehicle being repaired solely to allow the engineer to earn repair points, and to give back control when the repairs are done.

Resupply
Providing ammunition via an ammunition box.

Players only earn a finite number of resupply points for supplying a single player over one life. This prevents players from earning resupply points for wasting ammo or using grenade spam.

Battlefield 2 era
Though a supply drop provides many forms of support, commanders do not earn teamwork points.

Battlefield Heroes
Players earn XP for support actions in an amount corresponding to the hit points restored to another player or vehicle. This is similar to how XP is awarded for damage to enemies.
