The Military Human Rights Center for Korea (MHRCK) claimed General Jang Jun-kyu authorised the ‘track-down process’ through social media and dating apps.
His investigation has resulted in 20 soldiers facing charges under military anti-homosexuality laws.
South Korea’s army chief is facing calls to resign amid claims he ordered a nationwide probe to root out and prosecute gay personnel.
‘Gen Jang is obviously incapable of leading the army,’ the MHRCK said in a statement.
‘He treated his men who did their best to protect their homeland as if they were culprits and made them suffer the most horrible fear — losing personal dignity.
‘He must take responsibility . . . and resign immediately.’
The army confirmed it ‘was punishing soldiers on service who have homosexual relations with soldiers’. But denied Jang ordered a wide-sweeping investigation.
‘The investigation team launched the probe after recognizing that an incumbent soldier uploaded a video of him having sexual intercourse with another male soldier on social media,’ the Republic of Korea Armed Forces said in a statement.
