Sentry Gun

The sentry gun killstreak reward is unlocked after spending 3200 COD points.
If you have selected to use the sentry gun killstreak reward then you will gain it when you have killed 6 enemies without dying.
When you have selected to use the sentry gun killstreak reward it will be dropped into the map via a care package.
You must be careful when choosing to use the sentry gun as the helicopter that drops the sentry gun killstreak reward on to the map can be shot down by your enemy and it will also give away your position on the map as the enemy will be able to see where it is being dropped if they can see the helicopter.
When you have received the sentry gun killstreak reward then you can select to place it somewhere on the map.
When you have selected where you would like to place the sentry gun killstreak reward then it will automatically be armed and start scanning the area around for enemies to kill.
When the sentry gun spots an enemy it will automatically start shooting at them to kill them.
You can disable a sentry gun by coming up behind it and stabbing it.
The sentry gun killstreak reward is especially good at protecting a base that you have captured but try to place it in a position that an enemy cannot sneak up behind it and disable it.
