Pentagon Confirms Two More U.S. Army Reserve Fatalities in Kuwait Drone Strike

The Pentagon on Wednesday named two additional soldiers killed in a drone attack at a U.S. military facility in Port Shuaiba, Kuwait. Major Jeffrey O’Brien and Chief Warrant Officer 3 Robert M. Marzan were reported among seven Army Reserve personnel who died; positive identification for Marzan remains pending with the medical examiner. The fatalities were linked to the 103rd Sustainment Command based in Des Moines, Iowa, and come as U.S. officials say the conflict with Iran is intensifying.

Key Points

  • The Pentagon named Major Jeffrey O’Brien, 45, of Iowa, and announced the believed death of Chief Warrant Officer 3 Robert M. Marzan, 54, of Sacramento, California, following a drone attack at Port Shuaiba, Kuwait.
  • Both O’Brien and Marzan were members of the 103rd Sustainment Command from Des Moines, Iowa, part of the Army’s global logistics and supply operation; four other soldiers from the same command were earlier identified as casualties.
  • The incident comes as officials describe the conflict as intensifying, with U.S. Defense Secretary Pete Hegseth stating the U.S. "can sustain this fight easily for as long as we need to." Sectors potentially impacted include defense and military logistics, as well as government operations supporting overseas deployments.

The Pentagon on Wednesday identified two more U.S. soldiers killed in the conflict with Iran, confirming additional losses from a drone attack that struck a U.S. military facility in Port Shuaiba, Kuwait. The deaths were announced following the incident on Sunday that claimed multiple members of an Army Reserve unit.

Officials named Major Jeffrey O’Brien, 45, of Iowa, as among those killed. The Pentagon also announced the "believed death" of Chief Warrant Officer 3 Robert M. Marzan, 54, of Sacramento, California, noting that positive identification of Marzan would be completed by the medical examiner.

Both O’Brien and Marzan served in the 103rd Sustainment Command from Des Moines, Iowa, which is part of the Army’s global logistics and supply operation. The announcement follows an earlier identification on Tuesday of four other soldiers from the same command who died in the same drone strike, marking those personnel as the first casualties associated with the war.

The four service members previously identified by the military are:

  • Captain Cody A. Khork, 35, of Winter Haven, Florida
  • Sergeant 1st Class Noah L. Tietjens, 42, of Bellevue, Nebraska
  • Sergeant 1st Class Nicole M. Amor, 39, of White Bear Lake, Minnesota
  • Sergeant Declan J. Coady, 20, of West Des Moines, Iowa

The Pentagon indicated that the two most recent identifications are part of the same unit and incident. The medical examiner will complete formal identification procedures for Marzan, according to the military statement.

The casualties were announced as the broader conflict shows signs of intensifying. U.S. Defense Secretary Pete Hegseth was quoted Wednesday saying the United States "can sustain this fight easily for as long as we need to," a comment that underscores official assurances about the military's capacity to continue operations.

Details in the official announcements have focused on the identities, unit affiliations, and the procedural step of medical-examiner confirmation for one of the deceased. The military has not provided additional operational or investigative findings in the statements released with the identifications.

This sequence of identifications highlights the human toll within the Army Reserve logistics command and the procedural steps the Pentagon follows in confirming servicemember casualties in overseas incidents.

Risks

  • Positive identification for Chief Warrant Officer 3 Robert M. Marzan remains pending with the medical examiner, creating an immediate procedural uncertainty tied to casualty confirmation - this affects military personnel administration and next-of-kin notification processes.
  • The attack and subsequent fatalities underscore the risk of further harm to U.S. military personnel stationed at overseas facilities amid an intensifying conflict; this represents an operational risk for defense and logistics units supporting the deployment.
  • The unfolding conflict and confirmed casualties introduce uncertainty for defense readiness and planning, with implications for defense resource allocation and sustainment efforts.
