Pins

Pins

Pins give 100 or 200 points each time they are earned, and usually even weak players can get a few in a game

Pins in Bad Company 2 are earned during combat, for various impressive feats of accuracy, brute force, vehicle expertise, and so on. There are forty to collect across all multiplayer modes. Unlike Insignias, they can be achieved multiple times, and are only given out for gallantry in a single round. As such, they have a much lower points total than Insignias.

Weapon Efficiency Pins:

These reward you for killing a certain amount of enemies with a single class of weapon in each round. Most are easy to get, though watch out for 4 melee kills in a round (if you are being chased by the same knife-wielding player every time you turn around, he may be trying to get this pin), 4 handgun kills (the MP-412 Rex is good for this), and 4 RPG kills, as these are particularly difficult to get. Note that even as a sniper you can get some other class-specific weapon pins, by using the G3 for example.

Assault Rifle Efficiency Pin: 7 Assault Rifle kills in one round [100 points]
Sub Machine Gun Efficiency Pin: 7 SMG kills in one round [100 points]
Light Machine Gun Efficiency Pin: 7 LMG kills in one round [100 points]
Sniper Rifle Efficiency Pin: 7 Sniper Rifle kills in one round [100 points]
Shotgun Efficiency Pin: 4 Shotgun kills in one round [100 points]
Handgun Efficiency Pin: 4 Handgun kills in one round [100 points]
Melee Efficiency Pin: 4 Melee kills in one round [200 points]
Emplacement Efficiency Pin: 6 kills with a weapon emplacement in one round [100 points]
Explosive Efficiency Pin: 4 kills with explosives in one round [100 points]
Grenade Launcher Efficiency Pin: 4 40mm grenade kills in one round [100 points]
Rocket Launcher Efficiency Pin: 4 RPG kills in one round [100 points]

Class-specific Pins:

These are rather self-explanatory. Resupply and Maintenance Ops are easy to get. The former can have you just leave your ammo crates around and wait for people to use them. Better yet, get your squad to do it! The latter checks off one repair every time the Vehicle Repair 20 comes up, so you can actually get this just by following the same tank around.

Resupply Ops Pin: Resupply 7 teammates in one round [100 points]
Maintenance Ops Pin: Get 7 Repair bonuses in one round [100 points]
Medical Ops Pin: Revive 5 teammates in one round [100 points]
Surveillance Ops: Get 5 Motion Tracker assists in one round [100 points]

Combat Pins:

These pins reward you for exemplary skill shown in combat. Most are easy to get through plenty of play time. Though 7 assists may seem like a tall order, it is surprising how often you get minor assists just by lobbing grenades or shooting enemies running in the distance. Spot them as you do it, to ensure someone finishes them off in good time. Combat Efficiency and Excellence requires patience, but will come up naturally given enough time – snipers are best for kills without dying, though a good tank team can replicate this. For the Squad Member pin, you are required to designate flags or M-COM boxes to attack or defend. When this is done successfully, one order has been fulfilled.

Kill Assist Pin: 7 Assists in one round [100 points]
Savior Pin: 2 Savior kills in one round [100 points]
Avenger Pin: 2 Avenger kills in one round [100 points]
Nemesis Pin: Kill the same enemy 5 times in one round [200 points]
Payback Pin: Kill your nemesis in one round [200 points]
Marksman Pin: 5 Headshots in one round [100 points]
Combat Efficiency Pin: Get 6 kills without dying in one round [100 points]
Combat Excellence Pin: Get 8 kills without dying in one round [200 points]
Anti Vehicle Efficiency Pin: Destroy 4 enemy vehicles in one round [100 points]
Squad Member Pin: Fulfil one attack and one defend order in a round [100 points]
Gold Squad Pin: Be part of the best squad in one round [200 points]
Ace Pin: Be the best player in one round  [200 points]

Vehicle Pins:

Some players thrive in vehicles, and this class of pin is for them. Roadkills are easy to get in vehicles such as Humvees, particularly in confined spaces around flags or M-COM stations. Air Warfare includes UAVs, while all of these vehicular pins (except for Wheels of Hazard) allow passengers to get the points even when using their regular weapons (i.e. as passengers). Cars are classed as land vehicles that are not tanks.

Wheels of Hazard Pin: Roadkill 3 enemies in one round [200 points]
Naval Warfare Pin: Kill 4 enemies with water vehicles in one round [100 points]
Air Warfare Pin: Kill 5 enemies with air vehicles in one round [100 points]
Tank Warfare Pin: Kill 7 enemies with tanks in one round [100 points]
Car Warfare Pin: Kill 4 enemies with cars in one round [100 points]

Game-mode specific pins:

Destroying 4 M-COM stations is the hardest task on this list. Try playing as a C4 class and using Destruction 2.0 on as many buildings as possible. This is usually more effective than arming manually. See the Rush section of this guide for info on which M-COMs can be destroyed in this fashion. Flags can be captured many times in Conquest, so getting 3 captures in each round is not too trying. The Defender pins are given whenever you kill someone near the M-COM or flag, so these are easier to rack up.

M-COM Attacker Pin: Destroy 4 M-COM stations in one round [100 points]
M-COM Defender Pin: Defend 6 M-COM stations in one round [100 points]
Flag Attacker Pin: Capture 3 flags in a round [100 points]
Flag Defender Pin: Defend 6 flags in a round [100 points]
Conquest Winner Pin: Win a round of Conquest [100 points]
Rush Winner Pin: Win a round of Rush [100 points]
Squad Rush Winner Pin: Win a round of Squad Rush [100 points]
Squad Deathmatch Pin: Win a round of Squad Deathmatch [100 points]
