The U.S. Army is investigating the death of a soldier during training in Georgia.
FOX's Dave Anthony reports:
2nd Lt. Michael Parros wanted to be Army Ranger, but the 21-year-old officer didn't make it through training. Parros died Wednesday, two days after he became sick at Fort Benning in Georgia.
An Army spokesman says Parros, who was from Walnut Creek, California, fell ill after he had finished a hand to hand combat session and went to dinner.
Doctors were treating him for unusually low sodium levels in the blood, which can occur after someone drinks too much water.
Ranger school is grueling, 61 days of training soldiers to overcome fatigue, hunger and stress during combat.
