The Brotherhood of Steel banner is a settlement object in the Fallout 76 update The Legendary Run. It has previously appeared as a static object in Fallout and Fallout 2, called the Brotherhood of Steel marker or marker for short.
It is a simple steel pole with the Brotherhood's emblem on the top, placed in a tire filled with cement. In Fallout and Fallout 2, the horizontal bar also includes a solid red banner.
The ability to craft it was the reward for completing the second stage of Project Alpha successfully during the Fortifying ATLAS community event. It was unlockable in the Atomic Shop and could then be crafted with two steel at any C.A.M.P. or owned workshop.
