LOUISVILLE, Ky. (WDRB) -- Soldiers used sledgehammers Monday to beat down the walls at Fort Knox.

The wall-breaking ceremony marks the start of construction to renovate a building the 1st Theater Sustainment Command will soon call home.

The unit of nearly 600 active-duty solders and civilian workers is moving from Fort Bragg to Fort Knox as part of the army's restructuring.

The First TSC overseas military operations in the Middle East. 

"Even though we're spread by thousands of miles from our forward element, soldiers and civilian workers here are as equally in the fight each and every day," said Col. Johnnie Matthews, 1st TSC Deputy Commander. "So we're grateful to be housed in one building that will lead to greater cohesion and greater efficiency."

The $20 million construction project is expected to take about a year, with most of the unit moving into Fort Knox by next July.
