In Sub Base, the two-story building with generators on the bottom floor and what appear to be servers on the top has a penetrable fence around the generators on the bottom floor. The sniper can then take a second shot through the window (it may help to find a decent-size, intact piece of the window through which to view a high-traffic area) and, hopefully, get a second one-shot kill, making each window potentially worth two FMJ bullet penetration kills. If a sniper can get a one-shot kill ( Stopping Power makes this easier) with their first shot through the window, it will only crack. 50cal, which have high damage multipliers). Shooting through windows is a highly effective way for a sniper to get FMJ bullet penetration kills for a sniper rifle (especially with the Intervention and Barrett. In game, the FMJ is effective on multiplayer maps with lots of cover, such as Skidrow, the offices in Highrise, and the bunkers in Afghan.įMJ on a Sniper Rifle causes the bullet animation to appear to "spread", making it much easier to see where shots fired from a FMJ-equipped sniper rifle come from. Because of this, if the player hits a surface when targeting an enemy, the enemy might hear the shot and escape, or turn and shoot back. It is also worth noting that while it does not make the bullets themselves louder, the impact of an FMJ bullet makes very audible sounds that any player within ear-shot can hear, even if that player is using FMJ in conjunction with a silencer. For some weapons, bullet holes appear larger while using FMJ. This makes them easily visible so others can tell whether or not an enemy player has the FMJ attachment, while also changing the sound of the bullet impact. If a player fires a weapon with the FMJ attachment, the bullets will be red tracers and a small rain of sparks will shoot from the bullets' impact point.


Getting 40 bullet penetration kills with the FMJ unlocks Extended Magazines for that primary weapon. Instead, it allows the bullets to penetrate thicker surfaces, as well as losing less damage through other materials. It does normal damage against enemies in the open, though the in-game stats show an increase in damage. FMJ is the replacement to the perk Deep Impact from Call of Duty 4: Modern Warfare, allowing bullets to penetrate surfaces more easily.
