SEOUL, South Korea: Marking a tougher stand against North Korea, South Korea held its first large-scale military parade in over ten years this week.
On display were weapons, including ballistic missiles and attack helicopters.
The parade is being held before next month's Armed Forces Day.
Speaking at a Seoul Air Base this week, President Yoon Suk Yeol warned against the use of nuclear weapons.
"If North Korea uses nuclear weapons, its regime will be brought to an end by an overwhelming response from the ROK-U.S. alliance," Yoon said, while addressing South Korean troops.
On parade will be thousands of troops and South Korea's domestically manufactured tanks and self-propelled artillery, along with attack aircraft and drones.
Also marching will be 300 of the 28,500 U.S. soldiers based in the country, the Defence Ministry said.
South Korea last hosted a military street parade in 2013.
Unlike his predecessor, South Korean President Yoon Suk Yeol has taken a hard line against North Korea, increasingly displaying weapons and military drills, to put North Korea on notice.
Yoon has told the North Koreans to expect a swift and overwhelming response against any attacks. He has also sought to reinforce the country's military alliance with Washington and Tokyo.
The parade comes one week after North Korea and Russia agreed to increase their military cooperation.
