South Korea put on the first large-scale military parade in a decade on Tuesday, with weapons ranging from ballistic missiles to tanks rolling through Seoul in a show of force as it takes a tougher stance against North Korea.

The parade marks the country’s Armed Forces Day, normally a muted event relative to the massive events the North has staged under leader Kim Jong Un that include strategic weapons such as intercontinental ballistic missiles (ICBMs).

In a speech at Seoul Air Base, President Yoon Suk Yeol warned Pyongyang against the use of nuclear weapons and pledged to ramp up support for the military and the defense industry.
