103rd Sustainment Command (Expeditionary)

Today, the 103d Expeditionary Sustainment Command pauses to honor those who made the ultimate sacrifice in service to this Nation.

We remember our six fallen Soldiers whose courage, dedication, and selfless service embodied everything the Army Reserve stands for:

MAJ Jeffrey O'Brien
MAJ Cory Khork
CW3 Robert Marzan
MSG Nicole Amor
MSG Noah Tietjens
SGT Declan Coady

Their legacy lives on in every formation, every mission, and every Soldier who wears this patch.

On this Memorial Day, we also honor all who have fallen before them, across every generation, every theater, and every branch who answered the call and did not come home.

To the families who carry this loss every day: we see you. We stand with you. We will never forget.

"All gave some. Some gave all."

🛡️Farewell to Safety Joe🛡️

Today we say goodbye to Mr. William J. Sahen, our Safety Officer as he heads to Japan.

Mr. Sahen has been the 103d ESC's safety officer protecting every Soldier, Civilian, and Family member in our formation. He supervised over 20 training exercises with an impeccable safety record, demonstrating unwavering commitment to our mission and enhancing our command's safety culture.

In recognition of his exceptional service from April 2020 to May 2026, Mr. Sahen was awarded the Department of the Army Civilian Service Commendation Medal, a testament to his sustained superior performance and lasting impact on our organization.

While we'll deeply miss his expertise and steady presence, we're excited for what's ahead for him. Please join us in thanking Mr. Sahen for his years of dedicated service and wishing him safe travels and continued success in Japan.

Nation 🌵

Soldiers from the 649th Regional Support Group sharpened their lethality and sustained readiness during crew serve weapons qualification at Fort McCoy , building cohesive teams who are combat ready.

649th RSG Soldiers rotated through day and night firing iterations on individual and crew‑served weapons, reinforcing the fundamentals of marksmanship, fire control, and safe weapons handling in a dynamic field environment. Crew serve weapons qualification not only validates our unit’s ability to generate trained and ready formations, it also strengthens small-unit leadership, communication, and trust under realistic conditions.

🦅 MISSION PREP COMPLETE! 🦅

From April 9–12, Soldiers assigned to the 646th Regional Support Group hit the ground running at Fort McCoy , knocking out critical pre-deployment training ahead of Operation Sentinel Justice (OSJ). This Battle Assembly was all about pushing our team through rigorous collective training and mission command integration.

Soldiers maximized time in the field by standing up a Tactical Operations Center (TOC) with a full COMMEX. We also led a massive RSOI and MASCAL exercise supporting the 371st TC DET, 376th FI BN, and 687th CSSB. To finish strong, Soldiers owned the night with NVG tactical driving and sent rounds downrange for Individual and Crew-Served Weapons Qualifications (IWQ/CSWQ). 🇺🇸💪
