 * For the similar perk in Call of Duty 4: Modern Warfare, see Sonic Boom

Danger Close is a tier two perk in Call of Duty: Modern Warfare 2 that increases explosive damage by 40%. The Pro version increases the damage of all explosive killstreaks, such as Chopper Gunner or Harrier Strike, by 40% and is unlocked by getting 100 kills with explosives while using this perk. It replaces Sonic Boom from Call of Duty 4: Modern Warfare and Fireworks from Call of Duty: World at War.

This perk is unlocked at rank 33 and is the last tier two perk unlocked.

Trivia

 * The title that one gets after getting 250 kills with explosives using this perk is 'Sonic Boom' a reference to the perk which Danger Close replaced from Call of Duty 4: Modern Warfare.
 * Danger Close is often used in conjunction with One Man Army to gain practically infinite amount of grenade launchers. However, this is very frowned upon by other players.
