Killstreaks

Three kills in a row = Recon Plane. You and your team can see the enemy even when they are not shooting at anyone.

Five kills in a row = Artillery. You can bring in artillery on the location of your choice.

Seven kills in a row = Dogs. You can bring in dogs that will come in and eat the enemy.

Getting a killstreak is the act of killing players on the other team in succession without dying. it is a difficult thing to manage to survive kill after kill. Sometimes you get shot from behind. Sometimes you get sniped. Sometimes you simply get outgunned in a one-on-one fight.

All killstreak rewards have to be activated manually. This means you do not have to use them right away. You may find it better to hold onto radar for the next round or wait for the enemy to be clumped up in one area before calling in artillery.
