"In case of provocations, I ask you to immediately retaliate in response and report it later," Yoon was quoted as saying by South Korean news agency Yonhap.
Yoon added that such a measure was necessary to "smash the enemy's desire for provocations." He specifically pointed to North Korea, saying it can undertake provocations at any time and is the only country in the world that reserves the right to a preemptive nuclear strike and invasion under its constitution.
Yoon reiterated his government's support for South Korea's servicepeople and vowed to address all their concerns, including pay raises.
