CoD4 Support

Here is the CoD 4 support section. Scroll down to see Vehicle and Destructible stat tables and descriptions.

As you rack up kills, you will be notified of support abilities that you can use. These should be used whenever you get them, as they can help your team immensely.

(But remember to save a UAV if you can for when there is no UAV online.) You can only have one support ability at a time, so be careful to use your ability before increasing your streak. If you die, you keep any support ability you had.

3-kill streak - UAV (Unmanned Aerial Vehicle): Scans the map for 30 seconds, pinging the locations of all enemies who don't have the UAV Jammer perk. Everyone on your team can see the pings.

Everytime a person uses a UAV, it resets the timer back to 30 seconds and does not stack. So if you can, it is best to save it and use it only when there is no UAV up or the current one is about to expire. (Thanks to nolimit1386 for this correction)

5-kill streak - Airstrike:
Be sure to check out OSR's Guide to Airstrikes.
If no jet icons are on the radar map, you may call an airstrike. The map will appear and you can click where you want the bombs to fall.

The area around your click will be bombarded with three strikes in quick succession. Try to hold your strike until your team's UAV is active, and don't bomb enemies under solid roofs (it won't do anything). This support can sometimes be more effective at taking out enemies than the helicopter, so make sure to use it before racking up a larger kill streak.

Be extremely careful when using this on a friendly fire server! Also, consider saving it for critical offensives or saving efforts in Headquarters, Sabotage, Search and Destroy, and Domination.

7-kill streak - Helicopter: (For detailed helicopter stats click here.) If no helicopter icon is on the radar map, you can call an AI helicopter gunship to fly around the map shooting at any enemy it can find. The chopper has missiles and a minigun with considerable bullet penetration.

Any kill the chopper makes goes towards your kill count. If you're dealing with an enemy chopper, shoot at it if your fire won't give your position away to the enemy. All bullets that can reach the chopper (i.e. not shotgun shells) will damage it, and every little bit helps.

RPGs usually either kill choppers or reduce their HP to within a few bullets of damage, but LMGs also do considerable damage. Some servers have custom settings for the chopper's HP; I recall a server where the chopper spawned with only one HP! Don't count on something like that, though.

CoD4 Vehicle and Destructible Stats

Stats about the vehicles and destructibles in Call of Duty 4. Thanks to Denkirson for this information.

Note: For range, you can see a rough estimate on the stats overview page.

Object	Health	Effects	Action	Other	Notes
Helicopter	1100 Becomes weak after losing 500 health.	30% Bullet Dmg After being weakened, takes full bullet dmg	Lasts for 1 minute Attacks more aggressively after weakening After being weakened, takes full bullet dmg	Will target players with LMG or RPG-7 first over other players (And of course people with the highest scores and anyone shooting at it.)	Helicopters enter the map from one of several directions and travel between pre-determined points (with a bit of randomness) around the map until it loops back to the beginning. The loop lasts at least one minute, give or take a while depending on the map. After losing about half of its health, the helicopter engages "Evasive Maneuvers" state and is "weakened" against bullets, which now do full damage. It will randomize its the path for a moment, then travel from point to point more quickly and spend less time hovering in place.
Car	550 Catches fire after taking 550 damage.	Once on fire will explode ~10 seconds after. Can be attacked to cut time.	Blast Radius: 0-375 Damage: 250-1	Explosives do 2.75x more damage to cars so it can be destroyed with one explosive	Cars have a total of 1300 health, cut into multiple states. The first totaling 550 health, the next of 750 health. Once the car takes 550 damage, it catches fire and loses 60 of its 750 points of damage per second, and will explode once its health runs out. The splash damage of explosives are scaled up against cars so a single blast can detonate or set it on fire immediately.
Oil Drum	150 Catches on fire from any damage.	While on fire will explode after 10~ seconds, can be attacked to cut time	Blast Radius: 0-250 Damage: 250-1	Stopping power gives no damage boost against any of these objects or vehicles	Watch for enemies close to oil drums, if you see them camping next to one, shoot the oil drum for a funny kill.
