Pictures show organised lines of men from the country's armed forces cheering and raising their fists during the parade, in front of the capital's Fatherland Liberation War Victory monument.
It comes days after tens of thousands of placard-waving civilians staged a similar rally in the city.
This morning, Pyongyang's KCNA agency warned America that it is a 'tragedy that the reckless and hysteric behaviours may reduce the U.S. mainland to ashes any moment.'
The ranting statement said that it was the country's 'steadfast will...to put an end to the hostile moves of the U.S. which has imposed misfortunes and sufferings upon the Korean people for over half a century and win the final victory in the stand-off with imperialism and the U.S.'
It added: 'The U.S. and its vassal forces will dearly pay for the harshest sanctions and pressure and reckless military provocations against the DPRK.'
The latest show of defiance comes after Washington warned North Korea this week it faced 'fire and fury like the world has never seen' if it continued to threaten the US with its missile and nuclear programmes.
North Korea followed up the warning by threatening to send four missiles towards the American island of Guam - a threat that sparked yet another war of words between the country and US President Donald Trump.
Amid heightened tensions this morning, a Chinese state-run newspaper called on Beijing on Friday to 'stay neutral' if North Korea strikes first in a conflict with the United States, despite a mutual defence pact between the Asian allies.
