The Bartertown Security Force, also known as "Bronzers" is a group of people that protect Bartertown. Their leader is the Sheriff.
They are characterised by their dark plastic combat-armour and their Punk-styled feathered headdresses. The term "Bronzer" comes from the heavy leather belts studded with bronze that they wear. They are made up of both men and women, and brandish weapons such as spiked batons, whips, chainsaws and even Japanese Nunchaku.
The Bartertown security force reside in the Bartertown area, although it remains unclear if they regularly patrol the Bartertown railroad tracks or if when they did it in the movie that was the only time meaning that it might not part of there jurisdiction.
