Link to Build it bigger: Battle machines documentary
Documentary Description
At Kentucky's Fort Knox Armor Center, Danny gets
behind the wheel of the U.S. Army's most potent land weapon: the $5
million M1 Abrams tank. He also visits the Anniston Army Depot in
Alabama, where in just 55 days a battleworn Abrams can be made good as
new. Find out if Danny has what it takes to become a tanker — the
special breed of soldier that operates this 70-ton machine.
