Killeen, Texas (CNN) -- The gunman quickly reloaded his weapon, methodically moving away from Spc. Logan Burnette after shooting him several times during last week's deadly rampage at the Fort Hood Army Post.
"He was very swift, very tactical," Burnette told reporters Wednesday outside the Metroplex Adventist Hospital near Fort Hood.
Burnette recalled the events of Thursday's mass shooting that left 12 soldiers and one civilian dead, and more than 40 others wounded. It was the deadliest shooting ever on a U.S. military base.
Fifteen soldiers remained hospitalized on Wednesday, Fort Hood spokesman Col. James Rossi told reporters. Of those, four were in intensive care. All the soldiers were in stable condition, he said.
Burnette still has a bullet lodged in his right hip, he told reporters shortly before he transferred to the Brooke Army Medical Center in San Antonio, Texas. That is the same medical center where the suspected shooter, Maj. Nidal Malik Hasan, is being treated.
"I took one round to my hip, which tore through my hip on the left side, through my abdomen ... and is still lodged in right side of my hip," Burnette said.
"After the hit, I fell down, not even realizing I had been hit," he said. "As I tried to get back up, I was shot in elbow on the left arm and ... the knuckle on the left pinky finger."
Burnette said he then crawled to a nearby cubicle where he hid with two other soldiers.
A few minutes later, they decided "it was time for us to get out of that building," Burnette recalled.
"So we grabbed each other, they helped me up to my feet because I couldn't move," he said. "As I started to run, I fell again, not realizing I couldn't use my left leg."
After falling again, Burnette said he "threw all of my body weight ... towards that door as hard and as fast as possible."
"Once I hit that front door, I began to low crawl, about five meters up a hill just, you know, pushing my body forward with everything I had," he said.
Once outside those doors, a fellow soldier pulled him by the collar and dragged him to a nearby building and locked Burnette in the office.
He described lying there bleeding while the gunshots continued to ring out next door. He said he was safe at that point, but thinking of his fellow soldiers who were still there, defenseless with no weapons.
"There were a lot of heroes that day and by no means am I to take precedence over them," Burnette said. "There's a lot of heroes still in Iraq and Afghanistan and they do not need to be forgotten either."
He said he hopes to "recover and return to active duty as soon as possible."
Rossi said authorities remain committed to assisting those affected by the incident and their families, both physically and emotionally.
"In behavioral health, we could be at the eye of the storm, because it might take some time for some of these problems to manifest themselves," he said. "We're committed to finding them as soon as possible."
Army 1st Sgt. James McLeod, of Fort Hood's 467th Combat Stress Control Detachment, told reporters he was there when the shootings occurred.
"Everyone went into doing their job immediately," he said. "... Just soldiers taking care of soldiers."
"I can't really say that the perpetrator of this was really one of our own," McLeod said. "Soldiers do not do this to each other, so this is something a little bit different."
