A soldier assigned to the Hawaii Army National Guard’s 29th Infantry Brigade Combat Team collapsed and died last night after completing a six-mile run at a North Fort Hood training range in Texas.

The soldier’s name was not released pending the notification of his family.

More than 2,000 soldiers belonging the Hawaii unit are in the final phases of their training before they leave for Kuwait on Oct. 22 for a year’s tour. Of that number about 1,200 are from Hawaii.

Army officials at Fort Hood said the soldier collapsed shortly after the training run. Fellow soldiers could not find a pulse and began CPR and mouth to mouth resuscitation.

An ambulance took the soldier to the Coryell County Memorial Hospital in Gatesville, Texas where he was pronounced dead on arrival.

The cause of death is undetermined and the incident is under investigation, the National Guard said in a statement.

The 29th Brigade  is commanded by Col. Bruce E. Oliveira. The brigade’s soldiers come from all islands in Hawaii and the Pacific islands of American Samoa, Guam and Saipan. For this second deployment it also has been augmented  with soldiers from mainland National Guard and Army Reserve units.
