USFK has some new capability forward deployed on the peninsula:
The U.S. is to deploy new attack drones in South Korea that could be used to kill North Korean leaders and launch pinpoint strikes on its missile launch pads.
Twelve Gray Eagle/MQ-1Cs will arrive at an air base in Gunsan, North Jeolla Province in March and April. Their deployment coincides with joint South Korea-U.S. drills that will be staged in early April right after the closing of the Winter Paralympics in Pyeongchang.
Construction of a hangar and other support facilities was completed late last month, and support personnel have already arrived. [Chosun Ilbo]
