Early Saturday morning, U.S. Air Force security guards at Joint Base San Antonio-Lackland exchanged gunfire with unknown assailants in a dark sedan who fired at the main gate of the Chapman Training Annex. The initial shooting occurred around 4:30 a.m., and the suspects returned to fire again later. No injuries were reported, and the gate was temporarily closed while security was heightened. The motive behind the attack remains unclear, and it is confirmed that the shooters are not affiliated with the military. San Antonio police are collaborating with base officials to investigate the incident, which follows a previous 2016 murder-suicide at the base. The base resumed normal operations later in the morning.
