The Hawai'i Army National Guard soldier who died earlier this week after training at Fort Hood, Texas has been identified as Sgt. Julian Manglona, an Army Reserve Soldier from the 100th Battalion.

Manglona, who was assigned to the 29th Infantry Brigade Combat Team, died Thursday evening after completing a six-mile run about 7 p.m. at the North Fort Hood training area. The combat team headquartered at Kala'eloa is the largest unit of the Hawaii and had been in the Central Texas Army facility to conduct mobilization training.

Fellow soldiers training with Manglona performed CPR and mouth-to-mouth resuscitation. He was taken to Coryell County Memorial Hospital in Gatesville, Texas where he died.

The official cause of his death is unknown at this time, U.S. Army Reserve public affairs officer Brian Melanephy said in a prepared statement.

In August, about 1,200 soldiers with the 29th Infantry Brigade Combat Team, left for training at Fort Hood. The unit is scheduled to be deployed to the Middle East later this month. This is the second combat deployment for the 100th Battalion.

Brigade soldiers are responsible for providing convoy security escorts into Iraq in armored Humvees and Heavily Armored Mine Resistant Ambush Protected Vehicles on missions as far north as Mosul.

The brigade is made up of soldiers from Hawai'i, Arizona, American Samoa, Guam and Saipan.

"When soldiers train and deploy together they too become like a family," said Brig. Gen. Alexander Kozlov, commanding general for the 9th Mission Support Command in a prepared statement. "We are grieving rightnow.Our thougths and prayers are with Julian's family and our solderis during this difficult time."
