The 2017 situation in Asia is likely to be tense because of Trump and China in 2017 it will clearly get into danger zone fast if South Korea thinks it can get way with provocations as well.
South Korea's defence minister Han Min-Koo said the special unit, known as the Korea Massive Punishment and Retaliation (KMPR) plan, would now be launched two years ahead of schedule.
"We are planning to set up a special brigade with the goal of removing or (at least) paralysing North Korea's wartime command structure," he told acting President Hwang Kyo-ahn, according to the Yonhap news agency.
He also warned of a "strategic or tactical provocation" from the North in the coming months.
The military unit forms part of a three-pronged defence strategy which includes an anti-missile system - the Korean Air and Missile Defence (KAMD) - which would trace and shoot down missiles heading for South Korea.
There is also a "Kill Chain" pre-emptive military strike programme to counter an imminent threat.
