The Global Hawk has a jet engine. Most of them have piston engines.
As fighters mostly; no jets clashed in WWII, that came in Korea five years later. Britain did use some jets to "tip the wings" of some V1 buzz bombs over England, causing them to lose course and crash harmlessly. V1s were early relatives of todays UAVs.
UAVs are unmaned aircraft controlled by those in the army
everything but uavs and counter uavs If ur asking about killstreak rewards
Yes, UAVs are in Iraq. There are many different types ranging from reconnaissance aircraft to UAVs that fire 2 Hellfire missiles. Most in Iraq are operated by the USAF but the Navy has UAVs, too. Unlike CODMW3(which ruins every good part and the training and dedication it takes to be in the military), UAVs have a wide variety of uses and functions.
Jets will always use some form of kerosene
I can see a squadron of jets in the sky today.
It displays signs of uavs in the air
I believe you get it for calling in 50 uavs.

The airborne technology that is used in the fighter jets is the airborne networking.
Airplanes are generally fixed-wing aircraft. Aircraft can mean any type of flying machine, from airships (balloons/blimps), jets, propeller driven airplanes, rotor-wing (helicopters), UAVs (Unmanned Aerial Vehicles), drones (about the same thing as a UAV), or the space shuttle.
