In December 1945, the Regiment, and the 41st Division, were deactivated in Japan, and left active service. The Regiment was re-organized in December 1946, with Headquarters originally located in Portland. In 1968, another re-organization reduced the Regiment to a single Battalion, and Headquarters was moved to Ashland. Units are currently located in Ashland, Medford, Grants Pass, Roseburg and Klamath Falls. The primary mission since WW II has been to train for war, though none of our units have been mobilized for a war mission since that time.
Training takes place locally most of the year.
The two week Annual Training normally is conducted at Ft. Companies have also traveled to England and Japan for training, and the entire 41st Brigade trained atJRTC in Louisiana in 1998. Though the 186th is less than 100 years old, its traditions go back to the mid 1800s. Militia units were formed as needed for the common defense, and this tradition continues in the State missions of the National Guard. Members of the 1st Battalion have been mobilized several times in the last few years to fight forest fires or provide assistance during floods.
