YONGSAN GARRISON, South Korea — Two more 2nd Brigade soldiers have been killed in Iraq, the Pentagon confirmed Thursday, bringing the brigade’s total to at least 21 deaths in the first three months of a one-year deployment.

Staff Sgt. Marshall H. Caddy, 27, was killed Tuesday in Khaladiyah when his military vehicle struck another military vehicle, the Department of Defense said. It was unclear what kind of vehicles were involved in the incident, which military officials in Iraq are investigating.

Caddy’s hometown was listed as Nags Head, N.C.

In a separate Khaladiyah incident on the same day, the Pentagon said, 1st Lt. Luke C. Wullenwaber, 24, of Lewiston, Idaho, was killed when a car bomb was detonated near his military vehicle.

Both soldiers were assigned to the 1st Battalion, 506th Infantry Regiment, which deployed to Iraq from Camp Greaves in South Korea. According to the Pentagon, the unit was conducting a “security mission” when both incidents occurred.

No information from their hometowns was available Thursday about either soldier.

The deaths capped a particularly painful week for the 1st of the 506th. Between Nov. 11 and Nov. 16, three of the unit’s soldiers were killed. Of the 21 confirmed casualties suffered by 2nd Brigade, 18 have come from wounds received in combat, according to Pentagon statistics.

Khaladiyah is west of Baghdad, near the restive cities of Ramadi and Fallujah. 2nd Brigade troops have been active in rounding up suspected insurgent fighters and seizing weapons caches, officials have told Stars and Stripes.

2nd Infantry Division officials will hold a series of memorial services on camps in South Korea next week for all of the 2nd Brigade soldiers killed thus far in Iraq. The brigade, which sent 3,600 troops to Iraq in the first shift of troops from South Korea to another combat zone, is headed to Fort Carson, Colo., after its stint in Iraq finishes.
