The US Space Force has settled on South Korea as the first international base as an added check on North Korea as tensions remain high. 
As recently as a month ago, the North Korean nation led by dictator Kim Jong Un tested long-range ballistic missiles that landed at sea near the coast of Japan. The country was banned by the United Nations from developing or testing missiles and nuclear weapons under several resolutions. 
One of the main tasks of the South Korean Space Force unit will be to monitor the air space operations in the region, which includes issuing missile warnings. 
As the U.S. extends its military presence, it's likely Beijing and Moscow will further scrutinize the region and the new unit. 
"The hope is that they see we are ready," said Space Forces Korea commander Lt. Col. Joshua McCullion, according to CNN. 
"Myself and my guardians are ready to go day or night," he added.
