<human>:  I have a question about the Base Realignment and Closure Commission. What was the BRAC?
<bot>: The BRAC was a commission that was created by Congress in the 1990s to review the military bases of the United States. The BRAC was tasked with determining which bases should be closed and which should be expanded. The BRAC was a controversial commission, and many people were unhappy with the decisions it made.
