Using the Defibrillator (Assault, Rank 4)

  1. Equip in Loadout → Gadget 1.
  2. See downed teammate (skull icon, 15s revive timer).
  3. Approach body → Hold Fire (RT/R2) to charge.
  4. Charge Levels: Tap = 20% health. Full charge (2s) = 100%. Overcharge (3s) = 150% (overheal).
  5. Release → ZAP → Teammate spawns on you with bonus health.
  6. Points: 80 (revive) + 20 (heal) + 50 (savior bonus if near death) = 150+ per revive.

Pro Tips

  • Revive > Kill: Assault = combat medic. Stay behind front line.
  • Defib as Weapon: Uncharged tap does 10 damage. Can finish wounded enemies (humiliating).
  • Clear Area First: Don't revive into fire. Smoke grenade (M320 SMK) covers revive.
  • Squad Revive Bonus: Squadmates give extra points.

Gadgets define class roles. Master them. That's the Battlefield way.
