Nearly a dozen Fort Bliss soldiers were injured "after ingesting an unknown substance" during a field training exercise on Thursday, according to the Texas-headquartered military base.
On Friday, the 1st Armored Division issued a press release indicating that the 11 soldiers who were injured in the incident remain under medical care at William Beaumont Army Medical Center since arriving early Thursday afternoon.
Two soldiers were in "critical status," the release said.
According to the release, "the soldiers fell ill after consuming a substance acquired outside of authorized food supply distribution channels."
The injured personnel have been identified as one warrant officer, two noncommissioned officers and eight enlisted members.
"We took immediate action to treat everyone involved with the best medical care available," Major General Sean C. Bernabe, senior mission commander of 1st Armored Division and Fort Bliss, said in the release.
