CNN reported that the suspected shooter, identified as Muhammad Youssef Abdulazeez, 25, is also killed.
FBI special agent in charge, Ed Reinhold, told reporters that it has not yet been verified whether the shooting involved an act of terrorism or it was a criminal attack.
"We are looking at every possible avenue, whether it was terrorism -- whether it was domestic, international -- or whether it was a simple, criminal act,” he said.
A White House spokesman said President Barack Obama had been informed about the shooting.
The suspect opened fire at a military recruiting centre and a Navy Reserve centre in different parts of Chattanooga, Tennessee on Thursday morning, shooting at the doors of a military recruiting centre at a strip mall on Lee Highway.
The US Navy tweeted that another shooting took place at the Navy Reserve centre on Amnicola Highway.

The gunman is believed to have first gone to a military recruiting centre in a strip mall and opened fire and then drove off to a Naval Reserve Center about 10 km away, killing fatally the four Marines before being shot.
Lockdowns had been put in many facilities near the crime scene such as a hospital, business, places, and a collage.
Hospital system spokeswoman Lisa McCluskey announced Memorial Hospital in Chattanooga is "on precautionary lockdown" due to the shooting incident.
"We have not received any shooting victims,we are still accepting new patients,”
The families of those killed are being notified of their deaths.
