Fort Stewart spokesman Kevin Larson said Wednesday none of the injuries are life-threatening. One soldier was taken to the Augusta burn center with second-degree burns. The others were treated at Fort Stewart for minor burns and dehydration.
Larson said the soldiers were driving an M-88 armored vehicle on a tank trail when they heard a hissing sound, followed by an explosion inside the crew compartment. The blast threw one of the soldiers out of the vehicle.
The M-88 is an armored tow truck used to move tanks and other heavy vehicles.
The Army is investigating what caused the blast. The soldiers' identities were not immediately released.
