When Army psychiatrist Nidal Hasan walked into the Fort Hood Soldier Readiness Processing Center and opened fire on soldiers within, he perpetrated the worst mass shooting on a United States military base in our country's history. Death on Base is an in-depth look at the events surrounding the tragic mass murder that took place on November 5, 2009, and an investigation into the causes and influences that factored into the attack.

The story begins with Hasan's early life in Virginia, continues with his time at Fort Hood, Texas, covers the events of the shooting, and concludes with his trial. The authors analyze Hasan's connections to radical Muslim cleric Anwar al-Awlaki and Al Qaeda in the Arabian Peninsula (AQAP) and demonstrate how radical Islam fueled Hasan's hatred of both the American military and the soldiers he treated.

Hasan's mass shooting is compared with others, such as George Hennard's shooting rampage at Luby's in Killeen in 1991, Charles Whitman at the University of Texas, and Virginia Tech shooter Seung-Hui Cho. The authors explore the strange paradox that the shooting at Fort Hood was classified as workplace violence rather than a terrorist act. This classification has major implications for the victims of the shooting who have been denied health benefits and compensation.
