Monday's Washington Navy Yard shooting rampage is all too familiar to victims of the 2009 attack on Fort Hood.

Less than four years after 13 people were killed and 32 others wounded on the central Texas post, tragedy strikes a military installation again, and again 13 are dead.

Fort Hood shooting victim Chris Royal was in pre-retirement class when he heard the news Monday.

"I immediately went to November the 5th and just had compassion for that area," Chris said.

Following the Washington Navy Yard shooting, Congressmen John Carter released a statement.

In it he said, "As the Representative of Fort Hood, this type of senseless attack strikes an incredibly deep and personal cord with me, and is a reminder of the need for increased vigilance in a post-9/11 world."

There have been more than 75 mass shootings across the U.S. over the past 30 years, two of them in and around Fort Hood.

Monday's attack stirred up both grief and compassion in police officers who responded to both the 1991 Luby's massacre in Killeen and the 2009 shooting rampage on post.

"It does bring back memories of things that happened to us four years ago, and it's not something that we want to hear happened to anyone else," said Carroll Smith with the Killeen Police Department, "Our thoughts and prayers are with, not only the victims in the shootings, but as well as the victim's families."

Chris worries about the way the Military classifies insider attacks at home, especially after its justice system's lack of terrorism charges was highlighted in the Nidal Hasan case.

"I think that a vast majority of people see that, and so I think we're going to continue to have situations that pop up here and there," Chris said.
