Greatest Killstreaks In Call of Duty

RC-XD

I always found the RC-XD to be one of the most awesome and sneaky kill streak rewards. The RC-XD stands for Remote Controlled-Explosive Device. It can be activated by the player at any time, but has a time limit after which it will automatically explode, so make sure it’s close to an enemy when it does. It will give you a heads up when it’s about the explode too, as the RC-XD will beep repeatedly at a faster and faster rate until it goes boom.
