In February, we conducted the Retirement of the Colors Ceremony for the 438th Chemical Company at Stout Field. It was a solemn yet deeply meaningful moment as the Company formed for the final time and the colors were cased, marking the end of an era in the unit’s history.
In attendance were current Company, Battalion, and Brigade leadership, former command teams, families, and most importantly the Soldiers who were the heart and spirit of the unit. Their dedication and service are what truly defined the legacy of the 438th.
We sincerely appreciate everyone who attended the ceremony in person and those who joined us via the live stream. Your presence, whether near or far, helped honor the legacy of the 438th Chemical Company and the Soldiers who made it what it was.
Please read below for the unit history.
The 438th Chemical Company was established in 1980 in Terre Haute, Indiana, and quickly built a reputation for excellence through disciplined training and mission readiness, earning national recognition as one of the top Army National Guard chemical units. Over the years, the company adapted to evolving mission requirements through multiple reorganizations while maintaining its core identity and operational effectiveness.
It later relocated to Stout Field in Indianapolis, where it aligned with broader operational commands and continued to expand its capabilities. The unit played a key role in supporting mobilization efforts during Operation Iraqi Freedom and, since 2011, has served as part of a CBRN Enhanced Response Force Package (CERFP), maintaining readiness to respond to domestic emergencies involving hazardous materials.
The company has also participated in international training exercises and partnerships, strengthening interoperability with allied forces. Most recently, it supported state missions during the COVID-19 pandemic, reinforcing its enduring legacy of readiness, professionalism, and service to both the nation and the state of Indiana.
From its activation in Terre Haute in 1980, through national recognition, organizational transformation, and continued service at Stout Field, the 438th Chemical Company’s history reflects a consistent legacy of readiness, professionalism, and service carried forward by today’s Soldiers.
