2.
A single grafitti artist working alone without the aid of others. Could have once been part of a unit but has left to make his own 'mark' on society.
The 'tags' left by a lone soldier are signified by a small 'L.S' beside their work.
An example of a lone soldier or 'L.S' is the infamous british tagger known as 'Banksy'. He has tagged up many of the world's major cities such as New York, Paris, 'London' and L.A.
