Body armor encompasses any material that can be added to a soldier's uniform that provides extra protection against certain weapons. Though body armor can increase a soldier's durability, the extra weight can limit mobility and increase fatigue.
In Battlefield 2, the Assault, Support and Anti-Tank classes carry Body armor. In the game files, these classes are considered "heavy troops", and while it's the level .init files that classify who gets body armor, it's always the aforementioned three.
Body armor reduces damage to the torso area by lowering the received damage multiplier to 0.66 compared to the standard 1.0 against small arms. This allows the user to survive 1-2 extra shots if they aren’t hit in the limbs or head. This ability comes at the cost of reduced mobility compared to kits without the armor – specifically, a shorter sprint, reduced from 10 to 8 seconds, a longer sprint recovery time at 20 seconds, up from 17 seconds, and a larger penalty to stamina when jumping. .50 cal rounds used by such weapons as the M2 Browning HMGs on top of the M1A2 Abrams and M95 are not affected, as they already have a lower 0.50 multiplier against infantry. Shotguns suffer a more significant pellet damage reduction of 0.52 against body armor. In effect, semi-automatic shotguns may require additional rounds to kill a target, although pump shotguns are still capable of one-hit kills at close range.
For example: a shot from the SVD (45 damage) to the torso of a Support will do 29.7 damage (45 x 0.66 = 29.7), thus making the Sniper require an additional shot to kill him. A headshot, however, will still be an instant kill regardless of whether or not the player has body armor.
In the Battlefield 2: Special Forces expansion, the Engineer is also given body armor.
Battlefield 2142 allows all players the choice to equip heavy body armor, which decreases a soldier's stamina capacity. Using heavy body armor causes the soldier to take less damage to the body and limbs. The player model also reflects the change, adding additional armor to the soldiers' limbs; this allows observant enemies to determine if they need to spend extra effort in assailing the player.
The Zeller-H Advanced Sniper Rifle in particular can kill a soldier in one shot to any part of the body, unless he is wearing heavy armor.
Battlefield: Bad Company 2
— In-game description
Ceramic Body Armor is a specialization featured in Battlefield: Bad Company 2 and is unlocked at rank 14. Increasing health by 25 points, it protects players from what would be a fatal hits from weapons. However, it won't protect players from Knife strikes.
In Hardcore, it is much less effective due to the player's health already being 60 by default, and the fact that weapons remain unchanged in the mode, leading to only a slight increase of 15 health points rather than 25.
ARMOR is a specialization in Battlefield 4 and is the first specialization of the Defensive upgrade path. As this is the first specialization available to new players, it is one of the most common specs carried.
Armor reduces any incoming damage taken to the torso area by 10%. Most primary weapon types will require an extra bullet to kill if the body armor absorbs the damage. This also prevents standard sniper rifles from earning close-range kills to the chest. Designated marksman rifles are excluded by their damage models, allowing them to remain consistent.
After the 2014-09-30 patch most of the automatic weapons had a damage nerf making the defensive perk less effective against these guns, as their damage model would at most ranges deal enough damage that 10% less would no longer matter. Only sniper rifles and the Phantom with broadhead arrow will require one extra shot to the chest to kill a heavily armored player.
As of the 2014-01-30 patch, handguns now generally inflict enough damage to not require an extra chest hit.

The Armored Insert is a gadget available in Battlefield Hardline for the Mechanic. It functions similarly to the ARMOR specialization in Battlefield 4, allowing to the player to take half as much damage from bullets to the torso. Unlike its predecessor, however, it is equipped as a gadget instead of functioning as a specialization, forcing the user to sacrifice another gadget for the extra armor.
World War I-era metal plate armor are worn by special classes in Battlefield 1 to give them extra protection against firearms and grenades. The Cavalry and all Elite kits wear armor. The Sentry receives the greatest damage reduction and coverage, as well as immunity to non-takedown melee attacks. Other elites have more exposed areas, with Cavalry taking standard bonus damage from headshots.
Armor Vests and Armor Plates are a series of gadgets featured in Battlefield V, usable only in the Firestorm gamemode. Armor Plates can be looted from the ground throughout Halvøy, and can be applied to the player to grant an additional, non-regenerative 50 point health boost. Armor plates can be damaged or destroyed by receiving damage - these can be discarded and replaced with a fresh plate if one is available. Up to five Armor Plates can be carried at once.
The amount of armor a player can apply is based on their current level of Armor Vest. By default a player is equipped with a level 1 vest that can hold one plate. Level 2 and 3 vests can be found in the game world and can hold a total of two and three plates, respectively. A full level three vest gives the player a 150hp boost - when fully healed, this gives them their maximum attainable health of 300hp.
- In Battlefield: Bad Company 2: Vietnam, this specialization is not displayed in the Weapons & Gadgets menu that displays all available specializations, but may still be used in the game.
- In Battlefield 2142, the player models change depending on armor level. EU light-armored soldiers appear European, while heavy-armored soldiers appear African. PAC light-armored solders appear East Asian, and heavy-armored soldiers more Central European. Light-armored soldiers have one shoulder plate, while heavy-armored soldiers have both shoulders plated and carry more leg armor.
- The Armored Insert in Battlefield Hardline was originally exclusive to the Enforcer class but this was later changed to become available to all classes. Since the game became less vehicle-focused than past installments, the Armored Insert was later made exclusive to the Mechanic class.
- In the campaign, some enemy targets visibly wear tactical vests, plate carriers, or load bearing vests. These targets are armoured, and are significantly tougher to take down.
