The history of gun attacks at military facilities in the United States in many ways reflects those in society at large: they run the gamut from domestic attacks and drunken fights to politically motivated massacres, including the 2009 killing of 13 at Fort Hood, Texas. But unlike the rest of society, the people who live and work on these posts often suffer from stresses caused by the trauma of war and serving in the armed forces. They often end in suicide.
Here is a brief recent history of shootings on the grounds of military installations:
November 2019: Three people were killed and multiple others injured, including two sheriff's deputies, in a shooting at Naval Air Station Pensacola in Florida. The shooter also was killed, according to the Escambia County Sheriff's Office and the U.S. Navy.

July 2015: A gunman killed four Marines in attacks on a military recruitment center and a Navy and Marines reserve center in Chattanooga, Tennessee. A sailor died two days later from his injuries. A police officer and a Marine recruiter were injured in the violence. The gunman, identified as Muhammad Youssef Abdulazeez, died after a shootout with police. Abdulazeez suffered from depression and drug abuse, his family later told The Associated Press. He also had downloaded audio recordings of Anwar al-Awlaki, the American-Yemeni cleric who was a recruiter for al Qaeda.
April 2014: Violence hit Fort Hood for a second time, when an Iraq War veteran opened fire on the base, killing three and injuring 16 others before committing suicide. Specialist Ivan A. Lopez, 34, shot himself when he was confronted by a police officer. Lopez was being treated for depression, anxiety and other behavior and mental issues, and was being evaluated for PTSD, military officials said.
March 2014: A sailor was killed while trying to stop a gunman attempting to board a ship in Norfolk, Va.

September 2013: Twelve people died and four were injured after a government contractor opened fire inside the Navy Yard complex in Washington, D.C., committing one of the worst attacks at a U.S. military installation since the November 2009 killing of 13 at Fort Hood. Gunman Aaron Alexis, who had just recently begun an assignment at the site, was shot and killed by officers. Authorities later said that Alexis, who appeared to target his victims at random, "held a delusional belief that he was being controlled or influenced by extremely low frequency, or ELF, electromagnetic waves.”

After his arrest, the FBI said bomb-making materials were found in his motel room and said he was in possession of a large amount of ammunition, weapons and a bomb in a backpack. The day after his arrest, Abdo shouted "Nidal Hasan, Fort Hood 2009" as he was escorted out of a Texas courtroom. In 2012, Abdo was sentenced to life in prison.
