Security forces at the Joint Base San Antonio-Lackland (JBSA) returned fire early Saturday on at least one drive-by suspect who is accused of firing upon the main gate at the JBSA-Chapman Training Annex, a JBSA spokesperson tells Fox News Digital. The officers were fired upon at around 4:30 a.m. by at least one suspect in a sedan and immediately returned fire. There were no injuries reported, and the gate was shut for a number of hours.
