Kim Jong Un carried out an inspection of his military this week, asking its troops to be ready for combat as U.S. chose its new president, state media reported. The North Korea leader, who has threatened war against the U.S. and South Korea, told each soldier to "do the work of many men" as combatants.

According to Pyongyang's state-controlled news agency KCNA, last week Kim visited a special assassination squad that trains soldiers to target South Korean politicians. Kim ordered the North Korean special operation battalion Friday to "eliminate the human filth occupying the [South Korean] presidential Blue House, military and the puppet government, all who have committed crimes that cannot be forgiven for all of eternity."

On Wednesday, KCNA reported that Kim expressed satisfaction regarding the level of intensive training the soldiers were receiving. 

"In highly turbulent conditions, a readiness to fight must prevail during waking and sleeping hours, and all must wholeheartedly take part in training," Kim reportedly said. The leader also inspected the quality of the bunkers and other military equipment.

North Korea has one of the world's largest militaries, with 1,170,000 troops for 2002-2012 from its population of 25 million. The United States, in comparison, has 1,410,000 military personnel.

The North Korean leader's inspection of his military comes amid reports that his wife Ri Sol Ju has gone missing.
