Scout (perk)

Scout is a Tier 2 perk in Call of Duty: Black Ops. It is roughly equivalent to the Iron Lungs perk from past Call of Duty games. It also shares an effect with Steady Aim Pro from Modern Warfare 2.

Overview
Scout doubles the hold breath time for scoped weapons, allowing 8 seconds of no idle sway. Its pro version halves the drop and raise times for all weapons, effectively doubling the speed at which the user switches weapons. This also applies to weapons picked up from dead players, and changing to equipment and grenades.

Pro Challenges

 * Secondary Kills — Get 50 kills with secondary weapons.
 * One Shot Kills — Get 50 One Shot, One Kill medals.
 * Headshots — Get 30 headshot kills.

Trivia

 * When trying to get the Secondary Kills challenge, the player cannot swap their current secondary with another weapon, such as another primary weapon. The kills will only count if the player uses their current secondary weapon.
 * When using an assault rifle or the AK74u with a grenade launcher, Scout Pro's effect enables the user to fire almost immediately after firing the launcher's last shot, or if the player needs to switch from his launcher to his weapon quickly if cornered. This is especially noticeable when using a gun with the GP-25, as it already has a faster draw and drop time than other grenade launchers.
 * When not using Ghost Pro, Scout Pro can be very effective for an anti-air class trying to take down a Chopper Gunner or Gunship. This is because of the new 3-second delay before the killstreak user sees a red diamond around the player immediately after the player respawns. When using Scout Pro and a launcher, right after spawning the player will have enough time to switch to their launcher, lock on, and fire before the killstreak user knows where the player is.
 * Scout Pro also shortens the amount of time it takes to call in killstreaks, such as activating the "detonator" when calling in a Spy Plane.
 * An easy way to get Scout Pro would be to use a L96A1 to get the One Shot Kills, a RPG-7 for the Secondary Weapon kills, and a good assault rifle such as the AUG or FAMAS for the Headshot kills.
 * Another easy way to complete the Secondary Weapon challenge is to use the Balistic Knife in Free-For-All and focus on only getting melee kills, which will count toward the challenge.
 * Hardcore modes will also make pistol kills much simpler, and will increase relative sniper rifle damage, making the likelihood of sniper rifle one-shot-kills much higher. The lack of ADS movement penalties on pistols might make pistol headshots easier too.
 * The icon resembles the Variable Zoom Attachment
 * In the Wii Version of Call of Duty: Black Ops, the perk icon is the L96A1.
