The First Aid Pack is an Assault gadget appearing in Battlefield 4 that quickly heals a wounded player back to full health. They resemble Bandages in Battlefield Play4Free—if the player receives damage or is suppressed, healing from the First Aid Pack stops and the item is spent. Assault players can also carry the Medkit in the other Gadget slot.
Much like Medkits in Battlefield 2, the player has a regenerating supply, but only 2 (3 with the Combat Medic upgrade path) can be deployed at a time. Like the Ammo Pack, the First Aid Pack can be thrown further than the Medkit by targeting a friendly player. Either pack will slightly home in on the targeted player while airborne.
The First Aid Pack is consumed by any wounded player that passes near it, restoring a block of 10 hit points each second until they are healed or take damage. This in contrast to the medkit, which is a stationary object that increases the health of any soldier(s) standing around it at a slower rate. A single First Aid Pack regenerates after ten seconds, allowing the player to maintain a constant supply.
The First Aid Box is featured in Battlefield Hardline as an immobile map interactable, displayed as a green, rectangular, wall-mounted First Aid Box. To heal themselves, players must hold down the interact button while looking at the pack. Health is restored in blocks of 5 hitpoints every half a second. Healing continues to full until the player lets go of the interaction button, or is damaged or suppressed.
- The First Aid Pack will ocassionally heal the player to 99% health instead of 100%.
