Forgive the drive by: One thing that I think we need to consider is that (in my very humble opinion) the US cannot "win" a COIN fight unless the the insurgency is directly threatening the overthrow of the US. The US cannot "win" in the Afghanistan, Iraq, (or in the Philippines where I am just departing from). Only the Afghans can win in Afghanistan, only the Iraqis can win in Iraq, and only the Filipinos can win in the Philippines. I think that we are trying so hard to "win" and win hearts and minds for the US that we undercut the necessary legitimacy of the indigenous government and security forces. We cannot win these fights ourselves, we can only help the indigenous governments and security forces to win. As we consider COIN strategies I think we need to think about who is really capable of winning.
Now to answer your question here are some excerpts from various definitions of insurgency. These are dated (from a paper I wrote in 1995 and Larry Cable has been discredited academicly but he still provides some useful concepts so these are pre-1995 definitions from Joint pubs and FMs).
1. Insurgency: An organized movement aimed at the overthrow of a constituted government through the use of subversion and armed conflict. (JCS Definition)
a. It is an armed expression of internal and organic (regardless of external support) political disaffiliation. May be offensive (revolutionary war) or defensive (separatist or autonomous movements). (Dr. Larry Cable)
b. A protracted political-military struggle designed to weaken government control and legitimacy while increasing insurgent control and legitimacy (FM 31-20 Special Forces Operations)
c. Each insurgency has its own unique characteristics based on strategic objectives, its operational environment, and available resources (FM 31-20)
(1) Revolutionary insurgencies seek to overthrow existing social order and reallocate power within the country.
(2) Other insurgencies seek to:
• Overthrow an established government without a follow-on social revolution.
• Establish autonomous national territory within the borders of a state
• Cause a withdrawal of an occupying power
• Extract political concessions that are unobtainable through less violent means
5. Some additional notes on insurgency for consideration.
a. Consider that there are generally four “elements” that may be involved in the insurgency:
(1) The insurgent
(2) The population
(3) The counter-insurgent (the existing government or occupying power)
(4) The peace enforcer or peace keeper (external nation or forces)
b. Key to understanding insurgency is that it is a political problem first and foremost which has implications for the military. However, an insurgency will ultimately be successful if the underlying political and socio-economic causes are not addressed,
c. The insurgent, the counter-insurgent, and the peace keeper/enforcer have only two fundamental tools to work with to accomplish their goals:
(1) The enhancement of popular perceptions of legitimacy.
(2) The credible capability to coerce
d. Success or failure is determined by each sides understanding, application, and the mixture of these tools (which is determined by the political leadership NOT the military leadership)
e. Remember that no armed political disturbances begin without significant lead times.
f. When is the US military committed to counter-insurgency? Usually during the guerilla warfare or, at worst, the war of movement phase. Guess what? The war is already lost especially if a thorough Phase I has been conducted. It is generally too late for the established government to initiate the political reforms necessary to defeat the insurgency. Therefore, the US military ends up conducting a military operation to counter a political problem which just adds strength to the perceived legitimacy of the insurgency. The signs of a latent insurgency are too often overlooked and unrecognized.
g. Some fundamental considerations needed for the mindset of dealing with insurgencies.
(1) Encourage improvisation by subordinates (can lead to valuable tactics and techniques; i.e., SF CIDG program in Vietnam or the USMC Combined or Civic Action Platoons (CAP in Vietnam).
(2) Orient on the “human terrain”. Think in terms of cultural historical, and psychological terms.
(3) The killing (military operation) is clearly subordinate to the psychological and political.
(4) Replace “shoot, move, and communicate: with “presence patience and persistence.” Someday, if you are successful, the mission will disappear, like a river flowing into a swamp. (Dr. Larry Cable)
You may consider these dated but I think they are still useful in understanding the types and nature of insurgencies.
