Fort Hood is one of 12 bases nationwide losing a 4,000-soldier brigade.
The brigade cut is part of a plan to restructure Fort Hood and other bases including Fort Bliss near El Paso.
The cuts at Fort Hood are expected to impact the 4th Armored Brigade Combat team known as "Long Knife." It is part of the 1st Cavalry Division.
The army will reduce its side by 80,000 soldiers over the next five years. That will reduce the ranks from 570,000 to 490,000 soldiers.
This current round of cuts is unrelated to the sequester.
