The search continued Friday morning for four service members who went missing when fast-moving Texas floodwaters swept away their truck Thursday, killing five fellow soldiers.
Three other soldiers inside the vehicle were rescued when the tactical vehicle overturned during a training exercise at Fort Hood military base. The soldiers were in stable condition and were expected to be released from the hospital later Friday, Maj. Gen. John Uberti said at a news conference.
"As you're all aware, this tragedy extends well beyond Fort Hood," Uberti said. "The outpouring of support from around the country is sincerely appreciated."
The Army said three of the bodies were first recovered downstream, while two more were found later that night. Their identities were not immediately released.
Aircraft, boats, dogs and "heavy ground equipment" were deployed by multiple agencies to search for the missing soldiers, who were from the 3rd Battalion, 16th Field Artillery Regiment, 2nd Armored Brigade Combat Team, 1st Cavalry Division.
Fort Hood spokesman Chris Haug said Friday that the training exercise was routine, and the unit of 12 soldiers had been learning how to drive their so-called Light Medium Tactical Vehicle. An investigation into what happened was ongoing, he added, and would include how the accident occurred as the unit maneuvered around Owl Creek.
The road they had been driving on "was designated a low-water crossing," Haug said, meaning it wasn't believed to be prone to flooding.
The search for the missing soldiers, meanwhile, could be hampered by more bad weather Friday — coming during a period of historic flooding across the entire state. Most of Texas was blanketed by flood watches and warnings as of 4 a.m. local time (5 a.m. ET) and some areas could expect another five inches of rain through Saturday, forecasters said.
Fort Hood in particular could expect "additional rain today" that could become "locally heavy," Weather Channel Lead Forecaster Michael Palmer told NBC News. "The ground is already saturated and the rivers are swollen so this is going to hamper flood relief efforts as well as the search."
The unit had returned from a nine-month deployment in South Korea earlier this year.
"Our thoughts and prayers go out to the soldiers, their families and the Fort Hood community," Texas Gov. Greg Abbott said.
The downpour was dumping up to 3 inches per hour in some regions on Thursday, according to Weather Channel meteorologist Jonathan Erdman, two days after Abbott declared a state of disaster for 31 counties.
At least six people died last week, according to the National Weather Service. Texas has also been carved up by more than half a dozen tornadoes over the past week.
It has been the wettest March-May period on record at Austin-Bergstrom Airport, San Angelo, and the College Station-Bryan metropolitan area. Roads have been closed across the state and there have been several other high-water rescues.
