North Korean state media has trumpeted how the country has gained an "invincible power that the world cannot ignore and no one can touch" under Kim Jong-un, an apparent reference to its nuclear weapons as Pyongyang prepares for a military holiday.
Monday will mark the 90th anniversary of the founding of the Korean People's Revolutionary Army, and international monitors say North Korea is likely to stage a major military parade or conduct other weapons displays.
North Korea has conducted a flurry of ballistic missile tests this year, with US and South Korean officials saying there are signs it could resume nuclear weapons testing for the first time since 2017.
A report by state news agency KCNA on Sunday listed the history of North Korea's military achievements - from its battles in the 1950-1953 Korean War and smaller skirmishes throughout the Cold War to the 2010 bombardment of South Korea's Yeonpyeong island, which hit military and civilian targets.
The North's military is equipped with offensive and defensive capabilities that can "cope with any modern warfare", KCNA said.
It praised Kim's "genius military ideology and outstanding military command and unparalleled courage and guts", and his leadership in gaining the country's "invincible power".
For weeks commercial satellite imagery has shown thousands of North Korean troops practising marching in formation at a parade training ground in the capital Pyongyang.
Analysts had predicted a military parade on April 15, which was the 110th anniversary of the birth of the late communist founder of North Korea Kim Il-sung, and the nation's biggest holiday, but only a small, civilian "procession" was reported.
Preparations have been ongoing, suggesting a parade could now happen on or around Monday's army holiday, according to 38 North, a US-based program, and NK News, a Seoul-based website that tracks the North.
North Korea's most recent parades have been held at night, and were used to unveil new weapons, including its largest Hwasong-17 intercontinental ballistic missile.
