MSDF meaning in General ?

The Missouri State Defense Force (MSDF), formerly known as the Missouri Reserve Military Force, is the official state defense force of Missouri. As a state defense force, the MSDF is a reserve military force which serves parallel to the Missouri National Guard. As the MSDF falls solely under the command of the state of Missouri, it cannot be federalized or deployed outside the borders of Missouri, unlike the National Guard. Although the MSDF and the Missouri National Guard are separate organizations, the MSDF's primary scope is to work alongside the National Guard during stateside operations, or in lieu of the National Guard when the National Guard is deployed outside of Missouri. Along with the Missouri Army National Guard, the Missouri Air National Guard, and the Missouri Naval Militia, the Missouri State Defense Force is recognized under Missouri law as part of the organized militia of Missouri.

The Missouri State Defense Force is a division of the Missouri Department of Public Safety.
