Hardline

Hardline is a Tier 2 Perk featured in Call of Duty: Modern Warfare 2, Call of Duty: Modern Warfare 3, Call of Duty: Infinite Warfare, and Call of Duty: Modern Warfare. It is also a Tier 1 perk in Call of Duty: Black Ops, Call of Duty: Black Ops II, Call of Duty: Black Ops: Declassified, Call of Duty: Online, an Elite perk in Call of Duty: Ghosts, a Tier 3 perk in Call of Duty: Advanced Warfare and Call of Duty: Mobile, a Bonus Perk in Call of Duty: Modern Warfare II, and a Gear in Call of Duty: Modern Warfare III.
==Call of Duty: Modern Warfare 2==
In Call of Duty: Modern Warfare 2, it allows the player to gain their killstreak rewards with one less kill. For instance, if the player had UAV, Care Package and Predator Missile as killstreak rewards, rather than needing three, four and five kills respectively, they would only need two, three and four kills respectively. It is useful for getting more expensive killstreaks, but for lower-tier killstreaks, it's not very useful. More experienced players who are capable of going on long killstreaks may find this perk a waste, freeing up space for something else better suited to their tastes. However, newer or less skilled players may find this perk very useful.
Hardline Pro is unlocked after obtaining 40 killstreak rewards (not getting at least a two kill streak 40 times, as some may think). The easiest way to do this is set the player's killstreak to the rewards that require the lowest amount of kills possible. Hardline Pro reduces the number of deaths needed for a deathstreak by one.
The "Preemptive Strike" title is unlocked by completing Hardline Pro I Challenge. The "Close Support" title is unlocked by completing Hardline Pro VI Challenge along with the perk emblem.
==Call of Duty: Black Ops ==
Hardline returns as a Tier 1 perk in Call of Duty: Black Ops.
===Overview===
Hardline reduces all killstreak requirements by one. Its Pro version allows the player to re-roll the Care Package killstreak by double-tapping the action button for console versions and the reload key for PC versions, which will change its contents randomly. A Care Package can only be re-rolled once, and will always change its content.
The effectiveness of Hardline is heavily dependent on the player's skill and the killstreak setup in use. Hardline can make it extremely easy to get small killstreaks such as Spy Planes and Counter-Spy Planes. With regards to higher killstreaks, Hardline can be of benefit, and can make a killstreak that's usually very difficult for the player to achieve on a killstreak, such as an SR-71 Blackbird or a Chopper Gunner, just in range that a player finds is realistic for their own standards. 
Hardline Pro is particularly helpful when using Care Packages. Not only are Care Packages easier to get, but the ability to re-roll the contents of a Care Package can make the Care Package killstreak have much greater overall potential by getting rid of less desirable contents such as ammo crates and Spy Planes. It makes the Care Package give good killstreaks more consistently. 
Originally, the SAM Turret, Sentry Gun, and Valkyrie Rockets killstreaks crates could also be re-rolled; however, the December 14, 2010 patch limited Hardline Pro's functionality to the Care Package alone. One also cannot re-roll booby trapped Care Packages, making it easier to tell if one has been hacked.
Below is a table showing the default Care Package probabilities compared to the re-roll probabilities. As can be seen, re-rolling favors middle killstreaks much more than Care Packages, while higher killstreaks are almost unchanged.
Reward 	Default %	Re-Roll %
Ammo 	20% 	9%
Spy Plane 	15% 	9%
Counter-Spy Plane	15% 	9%
RC-XD 	9% 	9%
Valkyrie Rockets 	5% 	9%
Mortar Team 	5% 	9%
Sentry Gun 	5% 	9%
SAM Turret 	5% 	9%
Rolling Thunder 	3% 	4%
Grim Reaper 	3% 	4%
Napalm Strike 	3% 	4%
SR-71 Blackbird 	3% 	4%
Attack Helicopter	3% 	4%
Death Machine 	2% 	3%
Chopper Gunner 	2% 	3%
Attack Dogs 	1% 	2%
Gunship 	1% 	1%
Hardline gives the player model medium body armor in the form of Kevlar vest, a helmet on some models and a radio device located on the character's shoulder. However, this particular device is only aesthetic; all players have a radio to call in Killstreaks.

== Call of Duty: Modern Warfare 3 ==

===Overview===
Hardline makes each pointstreak require one less point. This applies to all three strike packages and all of the point streak rewards, even the M.O.A.B. It is useful for getting more expensive killstreaks, but for lower-tier killstreaks, it's not very useful. More experienced players who are capable of going on long killstreaks may find this perk a waste, freeing up space for something else better suited to their tastes. However, newer or less skilled players may find this perk very useful.
Hardline Pro is unlocked by obtaining 80 point streak rewards using Hardline. The Pro version has two effects; it reduces the number of deaths required for a deathstreak by one, and it also adds one point to a user's point streak for every two assists earned. Hardline Pro can be easily unlocked when using the Specialist Strike package, as only a single point is needed to earn the first perk.
