The militaries of Korea and the United States will begin the Ulchi Freedom Shield (UFS) exercise, a regular combined drill to defend the Korean Peninsula in a contingency, on the 17th.
This year's UFS exercise runs through the 27th and will reflect lessons learned from war, analyzed from recent patterns of warfare.
The Korean military's participation is at the usual level of about 18,000 personnel, but the scheduled field training exercises (FTX) have been reduced to 14 integrated battalion-level or higher drills, compared with last year's 17 battalion-level and 22 company-level or higher drills.
Under the previous administration, combined FTXs were concentrated during the Freedom Shield (FS) exercise in March and the UFS period, but the Lee Jae-myung administration plans to distribute them throughout the year.
This UFS exercise will also partly conduct a joint South Korea–U.S. evaluation of the capabilities and systems needed for the transition of wartime operational control (OPCON).
Regarding this year's UFS exercise, North Korea on the 14th hinted at a possible show of force, with a Foreign Ministry Spokesperson's statement saying, "A resolute position will be clearly expressed to exercise the legitimate right to self-defense and to forbid threats and challenges."
In describing this drill, the U.S. military used the phrase "projecting combat power inside the first island chain," prompting observations that U.S. Forces Korea could take on a character extending beyond the Korean Peninsula.
In a press release on its participation in UFS, the U.S. 8th Army in Korea said, "This exercise includes rapid distribution and preparation procedures for Army Prepositioned Stocks-4, which will demonstrate the alliance's ability to rapidly project combat power inside the first island chain and secure key terrain."
The first island chain is a strategic concept proposed by the United States during the Cold War to block the Soviet Union and China from advancing into the Pacific, a strategic defensive line linking Okinawa, Taiwan, and the Philippines.
Ryan Ronald, public affairs officer for U.S. Forces Korea, when asked whether this UFS drill contains elements related to regional threats, said, "(UFS) is intended to respond to the security threats facing the Korean Peninsula."
