The Lachmann Sub in Warzone and Modern Warfare 3 is an SMG returning from the previous game and one commonly known by players as the MP5. The Lachmann Sub - or MP5 - is available to acquire, use, and customise in Modern Warfare 3 as part of the new Carry Forward system introduced with the release of the game.

In a penalty shoot-out, each team takes turns shooting at goal from the penalty mark, with the goal defended only by the opposing team's goalkeeper. Each team has five shots which must be taken by different players; the team that makes more successful kicks is declared the victor.

The rules for a penalty shootout are as follows: Both teams take five penalties each. A different player must take each penalty. The winner will be determined once the 10 penalties have been taken and there is a team with more goals or when either team establishes an insurmountable lead.
