The Dragonfire is a Support Killstreak that is acquired at 12 kills. It is also a possible loot item from a Care Package.
When deployed, the user will assume control of the Dragonfire, allowing the use of the mounted machine gun, and may fly around the map. As with all killstreaks, the Dragonfire has limited durability and ammunition, and as such can be shot down by enemies. Upon leaving it, the Dragonfire will crash to the ground and explode, however this will not damage nearby players.
The Dragonfire is one of the only aircraft that can access underground areas. This is a feature which other aircraft such as helicopters and Reapers lack in.
However, the Dragonfire is very vulnerable to gunfire, and as such can be easily destroyed by enemies. It is also possible to get shot down by SAM turrets, and as such it is best used to fire on enemies from a high altitude for suppressive fire, or used to assault enemies hiding in underground locations.
As mentioned, the Dragonfire can be extremely annoying to deal with as it can access all areas of the map. However, the Dragonfire, like all other killstreaks, can be destroyed with enough gunfire, or by an EMP.
SAM Turrets are another way to counter enemy Dragonfires.
