A Fort Carson soldier was killed Sunday when the vehicle he was riding in was hit by an insurgent’s bomb.

Spc. Tofiga J. Tautolo, 23, of Wilmington, Calif., died after the bomb went off in Bati Kot district of Nangarhar province in Afghanistan, according to the the Department of Defense. A cavalry scout, Tautolo was assigned to the 3rd Squadron of the 61st Cavalry Regiment, which is with the 4th Brigade Combat Team.

Tautolo was a former Marine who joined the Army on May 5, 2011, according to Fort Carson records. While with the Marines, Tautolo deployed twice — once to Iraq in 2008 and then to Afghanistan in 2009. Each deployment lasted about seven months.

He earned several medals, including the Navy Unit Commendation Medal, Fort Carson records show.

Tautolo’s death marks the fourth casualty for the brigade since its deployment in March to eastern Afghanistan, a rugged, mountainous region that has been a hotbed of insurgent activity.

The brigade is in the midst of a nine-month deployment to train Afghan troops and police near the Pakistan border while also rooting out insurgents and patrolling for Taliban moving between the two countries.

This is the brigade’s second deployment to that region. The first deployment, which lasted a year, began in spring 2009.

Tautolo is the 75th soldier from Fort Carson to die in Afghanistan. Another 258 soldiers died in Iraq.
