The July 2015 shootings at two US military facilities in Chattanooga were another in a long series of military base shootings across the US. Since World War II, shootings have taken place where soldiers attacked their fellow soldiers, or civilians have attempted to enter restricted facilities, with deadly results. Some were racially motivated, especially in the pre-Cold War segregated military. Others are acts of domestic terrorism, planned and carried out to inflict maximum damage.
But while the Chattanooga shooting looks to be the work of a radicalized convert to Islam, most of these attacks aren't. In fact, most military base attacks in the US have nothing to do with Islam, and instead are the work of soldiers or contractors with undiagnosed mental trauma. Many of the shooters had completed multiple tours of duty in Iraq and Afghanistan, and some had been wounded - suffering blows to the head that might have contributed to their later crimes. And a few look to be crimes of passion or disgruntled former employees out for revenge. As in the civilian world, the motives are widely ranging.This is a complete list of the known shootings on US military bases, including those at Army bases or Naval bases, since World War II.
