Army National Guard Lineage

Army National Guard lineage can be incredibly complicated and misleading.

Units are reflagged and renamed multiple times throughout their existence and as the units change in type, the numbers may no longer correspond to the predecessor.

Most units draw their lineage from location rather than type of unit.

As the force structure changes, the location and members of the unit often matter more than the unit itself when transferring lineage.

Also, as the force structure reduces the size of the National Guard units are folded together and share lineage.

In that case sometimes a Company in one unit may carry the lineage and honors of an entire Battalion of WWII, as seen with the Brigade Support Battalion (BSB).

Also, the Companies or Battalions of a WWII Unit may have become several units or several WWII units may be come one in today's force structure.

For example, the 180th Infantry of WWII is three units today and the WWII 160th Field Artillery Battalion (105mm Howitzer) and 171st Field Artillery Battalion (105mm Howitzer) are one unit today.


11-157th Infantry Regiment (Mountain)157th
              Infantry Regiment Distinctive Unit Insignia, Colorado National Guard is not the successor unit of the WWII 157th Infantry Regiment.

The successor units of the WWII Infantry Regiment are 3rd Battalion, 157th Field Artillery Regiment, part of the 169th Field Artillery Brigade; HQ 169th FAB (Field Artillery Brigade); and the 947th Engineer Company, Colorado National Guard.

As the WWII 157th Infantry Regiment converted to the 157th Field Artillery, Colorado National Guard. they assumed all of the WWII units lineage and battle streamers

When a new 157th Infantry was stood up, 1-157th Infantry Regiment (Mountain), Colorado National Guard, they did not get 157th Infantry Regiment’s lineage and battle honors because the 1-157th Infantry Regiment (Mountain) is not the direct descendant in continuous service.

The 1-157th Infantry Regiment (Mountain) lineage is completely separate from the WWII 157th Infantry Regiment’s lineage:
