This is a big change for the ROK Army with the merging of FROKA and TROKA into one ground command that will lead to a large reduction in leadership positions, but more responsibility for the ROK Army:
Official preparations are underway by the Ministry of National Defense to launch a Ground Operations Command, which will be central to the transfer of wartime operational control of troops and in defense reforms.
The Defense Ministry completed building facilities for the command within the Third ROK Army in Yongin, Gyeonggi, in October, a military source told the JoongAng Ilbo on Monday.
Starting from November, a temporary ground operations command was formed.
In an attempt to reform the military’s structure, the government merged the 1st and 3rd Armies to create the Ground Operations Command to lead frontline units in case of an emergency on the Korean Peninsula and will also function as the Ground Component Command.
The Defense Ministry did not announce the launching of a Ground Operations Command in its defense reform guideline for 2014 to 2030 released in 2014, leading to questions of how serious the ministry was about the plan.
Through the launching of the new command, the 1st and 3rd Armies will naturally dissolve. Thus, overlapping positions of the two armies are expected to disappear, which could mean as many as 10 general positions may be cut. Likewise, overlapping executive and commissioned officer positions are expected to decrease.
Once the Defense Ministry makes an operation plan for the command, it is expected to be tested out in the Ulchi Freedom Guardian military exercise in August 2018. (……..)
The Ground Operations Command is expected to be transferred the tasks of the Ground Component Command (GCC) as well. The GCC is charged with commanding ground operations of the ROK-U.S. Combined Forces during an emergency on the Korean Peninsula and carrying out wartime operational control.
The GCC is currently helmed by the deputy commander of ROK-U.S. Combined Forces Command (CFC). After the Ground Operations Command is launched, the deputy commander of ROK-U.S. Combined Forces Command can focus on the role of supporting the CFC commander.
U.S. and Korean army officials will revise the combined operation plans so that the new command will be able to take on the tasks of the GCC. [Joong Ang Ilbo]
