South Korea replaced its number two military officer on Tuesday in a shake-up that also promoted 10 two-star Army generals to the rank of lieutenant general.

Lt. Gen. Lee Jong-sup, the commanding general of the 7th Army Corps, was tapped as the deputy chairman of the JCS, according to the Ministry of National Defense.

Lt. Gen. Koo Hong-moo, who leads the Capital Defense Command, was named the deputy Army chief of staff.

Lt. Gen. Kim Jung-soo, commander of the Army's 27th Division, will succeed Koo, with Lt. Gen. Nam Young-shin, the 3rd Division commander, picked to head the Special Warfare Command.
 
One two-star Navy commander and a couple of two-star Air Force officers were also promoted by a rank each.

The appointments are a follow-up to the Aug. 8 reshuffle of the top military brass by President Moon Jae-in.

Moon chose Air Force Gen. Jeong Kyeong-doo as the JCS chairman after picking Song Young-moo, a former Navy chief, as his first defense minister.

The left-leaning president has pledged the reform of the 625,000-strong military force long dominated by the Army. (Yonhap)
