Military personnel from the US and South Korea have practiced combat methods together at a training range near Pocheon, South Korea.
The combined forces exercise included a series of air-and-ground assaults on a mock objective.
Participating forces were members of the US Army's Company B, 2nd Battalion, 12th Cavalry Regiment, part of the 1st Cavalry Division's 1st Armored Brigade Combat Team.
The US troops worked alongside soldiers from the South Korean army's 137th Mechanized Battalion, 16th Mechanized Brigade, 8th Infantry Division, to practise a series of manoeuvres with M2A3 Bradley fighting vehicles.
South Korean battalion commander lieutenant Kim Seung-kon said: "It's really awesome for me to conduct a combined arms exercise with US forces.
"During war we should be able to fight together. During peacetime, we need to familiarise with each other and train together so that we can fight."
The six-day exercise aimed to give the forces a better understanding of each other's battlefield capabilities.
During a combined-arms assault drill, South Korean troops manoeuvred their armoured vehicles across the battlefield, called in live 81mm and 4.2in mortar support.
The soldiers also operated a South Korean Cobra helicopter that fired live ammunition and launched smoke grenades to hinder the enemy's view.
Company B commanding office captain Steven W. Northrop said: "We were working side by side with our Korean allies.
"Every opportunity we had to pair a US Soldier with a Korean Soldier, we did every step of the way. We put our forward observer teams with our fires officer, with their forward observer. That was when they were firing their live mortar rounds."
