There's no one central list that's constantly updated that I'm aware of (though others may have better sources). Wikipedia has a listing here, http://en.wikipedia.org/wiki/Guerril...rical_examples but that has all the usual risks involved with wiki entries

Another source is the USMC's Small Wars Center of Excellence with both current and past insurgencies at http://www.smallwars.quantico.usmc.mil/sw_today.asp and http://www.smallwars.quantico.usmc.mil/sw_past.asp

There's also a good listing in a NPS postgraduate study on Why Insurgencies Fail - Appendix A has a list of post-WW2 insurgencies. I'm fairly sure the SWC Library has a copy of the paper. Finally, there's a list of insurgencies the UK has been involved in at http://www.britains-smallwars.com/main/index1.html
