These are the faces of the young men who were among the first to respond when two staff sergeants were seriously injured by North Korean landmines last week.
The three soldiers held a press conference Tuesday at a military hospital where they are receiving psychiatric treatment along with five others who were at the scene of the explosion.
Recalling the urgent situation when one staff sergeant first stepped on a mine, sergeant Jung Kyo-seong said numerous drills helped him.
"I instantly yelled 'the enemy's shell is dropping ' My only thought was to run to the injured troops because that's what I had to do."
Jung added that the chaotic situation, while tragic, also strengthend and reaffirmed comradeship.
"While I was treating the sergeant injured in the second explosion, he was telling the first injured sergeant to stay awake."
The trauma and wounds from the bloody landmine explosions are still raw, but the soldiers are already looking to return to normal duty.
"I feel ready to return to my division and carry out operations."
A determined Second Lieutenant Moon Si-joon, who immediately called for medical support after the blasts, said North Korea will have to pay the consequences.
"I feel like going back to the accident site and destroying North Korea's guard post. Just as our troops suffered, I am looking for an opportunity to retaliate."
It's a heavy sentiment shared by many South Korean troops along the front line.
