FORT KNOX, Ky. -- Heroes don't come along often, but when they do they tend to make an immediate and lasting impact, as was the case recently for a recruiting company commander.Capt. Young Youn, commander of the St. Paul U.S. Army Recruiting Company, St. Paul, Minnesota, was traveling home from work on the Metro Light Rail Commuter train when he became a local hero.Youn had just settled into his seat when he heard a commotion at the end of the next train car. He looked up to see an elderly woman being attacked by a group of young men and women."As soon as I saw that she was attacked, I knew I had to intervene," Youn said. Upon arriving at the next stop, the train doors opened and the woman, followed by the group, moved out onto the platform."I ran out trying to catch up before the woman was attacked again," Youn said.Not knowing if members of the group had weapons or if they were going to attack him, Youn stepped in and subdued two of the attackers, which prompted the others to disperse and flee.Youn, who has served more than nine years in the U.S. Army, said he followed the Army's rules of engagement by taking action, controlling the situation and protecting those around him from harm."I stayed with her to let her know she was safe and that I would not leave her until help arrived," Youn said.After dialing 911, Youn used his Army medical training to tend the woman's injuries until police arrived. While Youn does not know the woman's current condition or what happened to the attackers, he said he was glad he was able to help and prevent something more serious from occurring."Capt. Youn is an exceptional Army officer whose personality includes personal courage and selfless service," said Lt. Col. David Foster, commander of the U.S. Army Minneapolis Recruiting Battalion. "His responsiveness and sense of responsibility to protect those around him from harm stopped a situation which could have resulted in even greater injury.""Capt. Youn displayed tremendous personal courage and positively represented our Army and United States Army Recruiting Command," said Col. Wayne Hertel, commander of the U.S. Army 3rd Recruiting Brigade. "I am just glad he was able to be there and make a difference."In addition to his current job, Youn is also actively involved in his community, serving on the board of directors of Minnesota D.A.R.E. and as the chair of the D.A.R.E. Diversity Committee."This is another example of how our phenomenal recruiters are doing great things in our communities across America," Hertel said.
