Osterman, Sean Andrew

Sean Andrew Osterman was born on February 3, 1989, and grew up in Princeton, Minnesota. He enlisted in the United States Marine Corps and was trained as a reconnaissance Marine. By 2010, he was a Corporal serving with the 2nd Reconnaissance Battalion, 2nd Marine Division, based at Camp Lejeune, North Carolina, as part of the I Marine Expeditionary Force Forward.

Corporal Osterman was conducting combat operations in Helmand province, Afghanistan, in early December 2010. According to the Department of Defense, he sustained severe injuries from an improvised explosive device (IED) blast. He was evacuated from the battlefield for medical treatment and transferred to the Landstuhl Regional Medical Center in Germany, where he died from his wounds on December 16, 2010.

Osterman's death occurred during Operation Enduring Freedom, the U.S.-led military campaign in Afghanistan that began in October 2001. In late 2010, the conflict was characterized by intense counterinsurgency operations, particularly in southern provinces like Helmand, where IEDs were a leading cause of casualties for coalition forces.

His death was officially announced by the Department of Defense. A memorial service was held at Camp Lejeune. He was buried with full military honors at Fort Snelling National Cemetery in Minnesota.

Corporal Osterman was posthumously awarded the Purple Heart. He is remembered by his unit and community as a dedicated Marine. His name is inscribed on the Princeton High School Veterans Memorial and is listed on the Afghanistan War casualty rolls maintained by the U.S. government.
