The melee attack is a feature introduced in the SWAT 4: The Stetchkov Syndicate expansion pack. It allows the player to punch targets using their fist.
When encountering non-cooperative subjects, the player can press the 'B' (default) key to punch and bring about compliance from the subjects. Each punch have a reach of 170 units (3.4 meters/11.05 feet) and it will stun the target for 1.5 seconds. The punch will also deal 5 damage while subtracts the target's morale value by 0.4. The morale reduction is stackable per punch thrown against the target.
It should be noted that melee attacks are less-lethal, not non-lethal. If performed excessively the victim will become incapacitated, possbily breaking the Rules of Lethal Engagement. It is also not advised to perform melee attacks against civilians under any circumstances since it will automatically forfeit the "No civilians injured" score bonus earned in a mission.
Changes in Elite Force
In SWAT: Elite Force, each punch's reach has been decreased to 150 units (3 meters/9.75 feet) while the target's morale will be subtracted by 0.8, making it almost as good as Taser Stun Gun in forcing subjects to surrender.
