How important are counterinsurgency operations today?

COIN is important because it keeps reappearing whenever a state’s monopoly on violence collapses, but it’s also historically the most politically constrained form of war. If you look back, the logic is ancient: Romans in Judea, the Spanish in the Peninsular War, British campaigns across the empire, then the modern canon—Malaya, Algeria, Vietnam, Afghanistan.

A consistent lesson: tactical success doesn’t equal strategic success. Galula’s writing on Algeria and Thompson on Malaya both emphasize legitimacy, local governance, and intelligence networks more than “search and destroy.” The U.S. doctrinal arc (FM 3-24) tried to formalize that, but Iraq/Afghanistan also showed the limits: building a partner government is not a purely military task.

Today, COIN matters less as a stand-alone “campaign style” and more as an unavoidable phase: stabilization, security force assistance, protecting key populations, countering shadow governance. Armies should retain COIN competence, but the real determinant is political strategy and sustainable objectives—something history is blunt about.

From a practical standpoint, COIN drives totally different equipment priorities than near-peer warfare. In COIN you live in your kit for long patrols, checkpoints, and vehicle searches, so comfort and durability become combat multipliers.

You see it in choices like: lighter plate carriers vs max-coverage armor, good belt setups for hands-on tasks, gloves that still let you manipulate cuffs/zip ties, and optics that handle mixed distances (LPVOs/red dots with magnifiers). Boots and socks matter more than people admit—rucking day after day in heat/dust destroys feet faster than bullets do.

That said, today’s “COIN kit” is merging with conventional needs because everyone wants better comms, better night vision, and better IFAK placement. If a force trains for COIN, it should standardize on scalable loadouts: heavy for deliberate ops, light for presence patrols, plus strong ID/biometrics/recording tools where policy allows.

COIN is important, but not in the Hollywood way. The day-to-day is patience, repetition, and discipline: presence patrols, talking to locals, de-escalation, and then sudden spikes of violence.

In training, the biggest gap I saw wasn’t marksmanship—it was decision-making under ambiguity. In COIN you’re constantly weighing second-order effects: who owns that street, who’s watching, what happens if you detain the wrong guy, and how fast rumors spread.

Also, the “partner force” piece is everything and it’s hard. You can have great gear and great drills, but if the local security forces aren’t trusted or aren’t supported by functioning governance, you’re pushing a rope. So yes, forces should keep COIN training alive, but it needs to be realistic: language/culture basics, restraint, evidence handling, and understanding that it’s a long game with political limits.

COIN is important because politicians keep picking wars that turn into COIN whether the military likes it or not. But let’s stop pretending it’s a magic doctrine. Half the time “COIN” becomes an excuse to blur objectives: are we defeating an insurgency, building a state, or just managing headlines?

If you don’t have a credible local partner and a clear political end state, COIN turns into a forever mission with body-count metrics replaced by “progress” briefings. Drones and ISR don’t fix that; they just make it easier to look busy.

So yes, train for it—because you’ll get thrown into it. But don’t build your entire force identity around COIN again. Keep the capability, keep specialized advisors and civil affairs capacity, and be brutally honest about what military force can and cannot change.

COIN today is inseparable from ISR and data. Small drones, persistent surveillance, pattern-of-life analysis, and cheap loitering systems have shifted the detection/targeting cycle dramatically.

But there’s a catch: insurgents also adapt fast. They use commercial drones for overwatch, encrypted messaging for coordination, and misinformation to shape perception. In COIN, the information environment is not a side show—it’s terrain.

Where tech really changes COIN is in “find and fix” without heavy footprint: distributed sensors, aerostats, UAS teams attached to platoons, and AI-assisted fusion to connect tips, imagery, and incident reports. Still, tech is only as good as the human network and rules of engagement. If your targeting generates civilian harm or undermines legitimacy, the insurgency gets a recruiting campaign for free.

COIN affects armored doctrine more than people think. In Iraq and Afghanistan, armored vehicles shifted from maneuver breakthrough to protected mobility: MRAPs, up-armored HMMWVs, and later more emphasis on electronic countermeasures and blast-resistant design.

Tanks and IFVs can be useful in COIN, but they’re blunt instruments. The advantages are protection, intimidation (sometimes good, sometimes counterproductive), and the ability to dominate key routes. The downsides are maintenance burden, fuel logistics, and the optics of “occupation.”

Modern lesson: if you bring armor into a COIN environment, you need dismounted infantry, engineers (route clearance), and a tight civil-military plan. Otherwise you get predictable routes, IED vulnerability, and a force posture that distances you from the population you’re trying to influence.

COIN is often discussed as a land problem, but maritime COIN is a real thing: coastal insurgencies, piracy-adjacent networks, weapons smuggling, and shadow economies that fund armed groups.

Navies and coast guards become central in interdiction, maritime domain awareness, and training partner forces. Think of how controlling sea lines and ports can choke insurgent financing and resupply without “occupying” territory.

Today’s relevance is high in littoral regions where governance is weak and commercial traffic is dense. The hard part is legal and political coordination—rules for boarding, evidence standards, detention handoff—so navies need COIN-adjacent capability: intelligence fusion, small boat operations, and partner capacity building.

Airpower in COIN is a double-edged sword. ISR platforms, helicopters, and light strike aircraft can provide mobility, surveillance, and precision fires—but mistakes are strategically expensive.

One big lesson from the last two decades is that close air support in COIN isn’t just a weapons problem; it’s a communications and identification problem. You need trained JTACs, reliable comms, and tight positive ID standards. Otherwise the enemy baits reactions or hides among civilians.

Helicopters matter a lot for quick reaction, medevac, and moving small units without telegraphing routes. But the more contested the airspace gets (MANPADS, drones), the more complicated “classic COIN air mobility” becomes. Aviation still supports COIN, but it has to be integrated with the ground plan and information strategy.

From a career perspective, COIN relevance shows up in what militaries actually ask people to do: advising partner forces, stability missions, security cooperation, intelligence analysis, civil affairs, and language-enabled roles.

If you’re considering joining and you’re thinking “Will I be doing COIN stuff?”, the honest answer is: you might, even if the recruiting ads focus on high-end conflict. Many deployments are about deterrence, training missions, and operating among civilians.

Practical takeaway: build broad skills—fitness, navigation, communications discipline, basic cultural awareness, and professionalism under stress. If anyone is serious about joining, talk to an official recruiter for current requirements and be cautious about online hearsay.

COIN is basically the environment where special operations units are most consistently used, especially for foreign internal defense, advising, intelligence-driven raids, and building partner capacity.

But people over-index on “direct action.” The unglamorous pieces—training local units, mentoring leadership, setting up sustainable logistics, and building intelligence networks—often matter more than kicking doors.

Also, modern COIN has an interagency feel. Even elite units can’t substitute for governance and legitimacy. SOF can buy time and disrupt networks, but the strategic win depends on what fills the vacuum afterward.

At the small-unit level, COIN punishes basic fieldcraft mistakes. If you’re doing presence patrols and living out of small positions, the fundamentals—noise/light discipline, sanitation, water management, and consistent routines—matter.

COIN also means lots of interaction with civilians, so “fieldcraft” includes how you set up a position without wrecking local property, how you move through markets without creating panic, and how you keep yourself and your team hydrated and alert without looking threatening.

Not giving tactical advice, but in general: units that drill the boring basics (navigation, comms checks, first aid proficiency, equipment maintenance) tend to make fewer errors that spiral into bigger incidents—exactly what COIN environments exploit.

COIN is important today because many conflicts are political contests fought below the threshold of conventional war. Insurgencies are often tied to external sponsors, transnational criminal networks, or regional power plays.

The key question isn’t “Can we clear an area?” but “Can the state provide credible security and services afterward?” That’s where budgets, corruption, legitimacy, and intelligence penetration become decisive. If those pieces fail, tactical operations can actually amplify instability.

Social media and cheap connectivity have increased narrative velocity: one incident can reshape international support, partner cohesion, and recruitment for armed groups. So COIN now requires a strategy that aligns military actions, governance reforms, and information operations—otherwise the conflict stays stuck in a cycle.

COIN is a logistics and engineering grind. Route clearance, base hardening, power generation, water supply, maintenance cycles, and infrastructure repair can be more strategically meaningful than another kinetic operation.

Engineers also influence the “feel” of security: lighting, barriers, controlled entry points, and road repairs can reduce vulnerability and improve civilian life—if done with local input and not as a fortress mentality.

A big lesson is sustainability. Building projects that the host nation can’t maintain (parts, fuel, skilled labor) creates dependency and resentment. Modern COIN planning should start with what can be supported locally and how quickly responsibility transitions.

I’m still learning, but I’m confused about what “winning” even means in COIN. Is it like getting rid of insurgents, or is it more about making people trust the government?

Also, with drones everywhere now, doesn’t that make it easier to find insurgents hiding out? Or do they just blend in and it doesn’t change much?

If anyone has good book or documentary recommendations that explain COIN without being propaganda, I’d appreciate it.

In most strategy games and planning models, COIN is the scenario where “combat power” has diminishing returns and “control variables” (governance, legitimacy, intelligence quality, partner capacity) dominate outcomes.

That’s why COIN remains important: it’s the likely follow-on phase of interventions, proxy wars, and state failure. Even in near-peer conflict, you can end up with insurgent resistance in occupied or contested areas.

Force design implication: you don’t need an army that is only COIN-focused, but you do need modular capabilities—advisory teams, civil affairs, linguists, psychological operations/information support, police-like skills, and robust intelligence fusion—so you can scale to the problem without hollowing out high-end readiness.

Robotics will make COIN more persistent and more contested. Ground robots for route inspection, unmanned resupply, and remote sensing reduce risk to patrols, while autonomous perimeter systems can free manpower.

At the same time, insurgents can use cheap robots too: improvised UGVs, drone swarms for harassment, and automated propaganda amplification. The barrier to entry is low and getting lower.

The “importance” of COIN doesn’t go away—it evolves. The side that integrates human intelligence with robotic sensing, and does it under strict discipline and political oversight, will have an advantage. But if autonomy creates more civilian harm or unaccountable decisions, it backfires strategically faster than in conventional war.
