An IISS Strategic Comment which IMHO describes the chaos that is the new or is it the old Libya:http://www.iiss.org/en/publications/...-militias-d401

Here is an illustration:
The withdrawal of Misratan units was followed by that of other non-Tripoli militias, their place taken by the army's 151 and 166 brigades, newly trained and deploying with American equipment including tan-coloured humvees. Crowds cheered their arrival on the streets, though others remembered that the Misratans themselves had been cheered when they liberated the city two years before.
