Staying Healthy on the Bad Company 2 Battlefield
When a soldier really needs to be restored to health fast he turns to his Medic teammates. The Medic is a special breed of soldier, able to fight just as hard as their brothers in arms, but also dedicated healers. They keep their teammates in the fight as long as possible and to bring them back into the fight when they're down. In Bad Company 2 the medic has two tools to use to keep his teammates healthy.
The first tool is the Medkit, a portable first aid station that the Medic can deploy to heal the soldiers around him in the middle of combat. The Medkit begins working immediately and keeps working until the medical supplies are depleted. It also works in combat, so a soldier near a Medkit can duck behind cover to quickly heal up and be ready to get back in the fight. Just be careful where you deploy the Medkit, as even enemy soldiers will receive its healing benefits.
The second tool is the Defibrillator, also known as the Shock Paddles or the Defib for short. The Medic can use the Defib on his recently incapacitated teammates to bring them immediately back to full fighting strength. The Defib allows the medic to keep his squad and team together and fighting. In a pinch the Defib's electric shock can even be administered to healthy enemy soldiers, instantly incapacitating them.
Bad Company 2 introduces a system we call Out of Combat Healing. Like many features in Battlefield it's a reflection of a real soldier's world. Every soldier learns some basic first aid so he can patch himself up and get back into the fight. In Bad Company 2 we represent a soldier's first aid ability via the Out of Combat Heal. A soldier who's been wounded in a fight but survived will slowly heal himself. Out of Combat Healing is a not a fast process. Unlike your Medic teammate it's not going to save you in the middle of a firefight, but it will keep you from bleeding out somewhere alone on the Battlefield.
