San Antonio will host a U.S. Army training each night this week through Friday.
The downtown and central-area training will take place nightly from 6 p.m. to 3 a.m. It will include air and ground mobility operations and close-quarter combat training to simulate environments troops may encounter when deployed.
Residents around the area may hear low-flying helicopters, simulated gunfire and controlled explosions during the night.
The San Antonio Police Department will be on-site to protect participants and residents, and safety precautions are in place to minimize community impact.
SAPD Police Chief William McManus said in a statement the training was planned in advance months ago.
“We’re honored to provide support to the U.S. Army as they conduct this critical training in our city,” he said.
