Firefighters says they responded to more than 1,000 calls on Bonfire Night with crews "bombarded" by missiles and fireworks.
The Scottish Fire and Rescue Service said there were six incidents where teams were attacked - three in Clydebank, two in Edinburgh and one in Blackridge in West Lothian.
Police officers were also attacked with fireworks, bricks and bottles but said incidents of serious disorder had fallen this year.
The force said the attacks on emergency services was "wholly unacceptable" and officers were working to trace those responsible.
