While both the Dawn and Dignity camps have access to heavy artillery, tanks, and grad rockets the real difference between the weapons of the two sides is that Dignity has more aircraft and has access to munitions for these aircraft from outside of Libya. While Dawn has repaired some aircraft, this side has been flying far less sorties.
But the aircraft on Dignity side, including the ones that have probably used cluster munitions, may not be all that effective. Those aircraft fly and bomb at high altitudes, making them very inaccurate. Also, historical evidence suggests that aircraft alone are not decisive in victory. As the “balance of weakness” continues in Libya, it will be hard to end the ongoing conflict in Libya. This has made the conflict particularly bloody.
