Web Special: 54th Massachusetts Volunteer Regiment

A Massachusetts National Guard unit has a prestigious place in Tuesday's inauguration parade. The 54th Massachusetts Voluntary Regiment will be among those invited to march down Pennsylvania Avenue.

Originally the first African-American unit to fight in the North during the Civil War, the 54th was reactivated in 2008 to provide military honors at state functions and veterans funerals.

WBUR's Sarah Bush visited the regiment as its members were rehearsing for today's big ceremony.
