Azerbaijan and Armenia have now spent more than two weeks at war, with casualties mounting on both sides. On the morning of Sept. 27, Azerbaijan launched an offensive across the line of contact held by the Armenian military and local forces belonging to the breakaway region of Nagorno-Karabakh (sometimes referred to as the self-declared Republic of Artsakh). The fighting is the worst it has been since the Karabakh War of 1992 to 1994, encompassing the entire line of contact, with artillery, missile, and drone strikes deep past Armenian lines. This war features modern weaponry, representing a large-scale conventional conflict between these two states which will undoubtedly change the long-standing status quo. Turkey is backing Azerbaijan, seeking to leverage this conflict for foreign policy gains. Russia’s efforts to balance relations with all parties, while supporting Armenia, once kept the conflict frozen, but is no longer viable.

The 30-year dispute is over a majority Armenian region that had autonomy within the Azerbaijan Soviet Socialist Republic of the Soviet Union. In the late 1980s, it voted to unite with the Armenian republic instead. Upon Soviet dissolution, the newly independent Republic of Azerbaijan incorporated this region. A bloody war between Azerbaijani, and Armenian forces led to the de facto Armenian control over Karabakh and surrounding regions of what is internationally recognized as Azerbaijan. Since then, clashes and skirmishes have taken place in what was largely a frozen conflict, until 2016.

 

 

In 2016, Azerbaijan launched a limited offensive, seizing strategic heights and testing the ability of its forces to take on the Armenian military. More recently, serious fighting broke out in July of this year between the two countries, resulting in a Russian-brokered ceasefire, which was supposed to lead to negotiations. Armenia’s leadership, while not recognizing Artsakh as an independent state, has been broadly disinterested in negotiating with Azerbaijan, and its politically inexperienced Prime Minister recently made statements that exacerbated the situation. A week before the war started in September, Azerbaijan began calling up reserves, signaling that they were preparing for an operation.

The chances of this war becoming a broader regional conflict are low, but it should not be dismissed as a distant war between small states. On the contrary, these are sizable armies fielding armor, artillery, air defense systems, and more. On top of advanced capabilities, Turkey has supplied battle-hardened mercenaries from Syria to aid Azerbaijan in the fight, and Turkish F-16s are present in Azerbaijan, which suggests that Ankara has some role in aiding Azerbaijani efforts. Much of the war is playing out along Iran’s border. Moscow was able to broker a humanitarian ceasefire on Friday, but this reduction in the intensity of fighting only gives both sides time to reposition and resupply as the shooting continues.

In a short time, the war has already escalated to include shelling of cities, large caliber rocket artillery strikes, and use of short-range ballistic missiles. Much of the terrain is mountainous, highly favorable to an entrenched defender supported by artillery and missiles, but these positions are also vulnerable to attack from the air. While pressure has mounted on both parties to cease hostilities and declare a ceasefire, including from the Organization for Security and Co-operation in Europe’s Minsk Group, at the time of this writing there is no end in sight. The battle is likely to become more existential for both sides as political stakes and military costs mount.

This is a brief operational analysis of the current fighting and the military balance between the two sides. Azerbaijan’s initial combined arms offensive against Armenian lines was not successful in breaking through and securing territorial gains, but its forces have pushed back Armenian defenses in the south, along two vectors near the Iranian border. Azerbaijani forces have made minor gains to the north, and in a third sector of the line, but these aredifficult to discern due to the prevalence of false claims on both sides. Outside of the southern thrust, Azerbaijan has moved the line several few kilometers near Madaghiz and Merdinli.

Azerbaijan’s drone fleet has been pummeling Armenian forces, which are protected by antiquated air defenses. Both sides have employed large caliber rocket systems, cluster munitions, and tactical missiles against each other’s critical infrastructure. Armenia’s armor and air defenses are steadily wearing down but Azerbaijan has not been able to turn tactical successes into substantial operational gains. Ground assaults have proven costly, and rather than a blitzkrieg it has become a war of attrition. This conflict offers useful insights on the character of modern war, though mostly at the tactical level, which should be consumed judiciously.

The Military Balance

In general, Azerbaijan has quantitative and qualitative superiority over Armenia in terms of kit. While there is not a tremendous difference between the relative sizes of their armed forces, with Azerbaijan fielding 80,000 and Armenia 65,000 personnel, Azerbaijan also has access to several battalions of Turkish-supplied mercenaries from Syria, while Armenia can quickly mobilize additional fighters from the region of Nagorno-Karabakh. More significantly, Azerbaijan has made a qualitative leap since 2010, largely thanks to purchases from Russia, Turkey, and Israel. Thus, the Azerbaijani army has superior tanks, armored personnel carriers, infantry fighting vehicles, and light utility vehicles.

Azerbaijan has achieved a quantitative advantage over Armenia in the number of artillery systems, especially self-propelled and long-range multiple launch rocket systems. Armenian forces have such systems, but in significantly smaller numbers. Larger caliber rocket systems, like BM-30 Smerch purchased from Russia, can reach military and civilian targets well beyond the battle lines.

Where Armenia may have a minor edge is in tactical ballistic missiles. The country has at its disposal a brigade of Iskander-E systems (at least eight launchers, each carrying two missiles), capable of engaging objects across the territory of Azerbaijan (the maximum firing range is about 300 kilometers). The Armenian Armed Forces also possess eight obsolete SS-1C Scud-B missile systems, and at least four Tochka-U which have a range of 120 kilometers. Azerbaijan has three Tochka systems and Israeli LORA tactical missiles. This allows both sides to threaten each other’s critically important infrastructure or civilian population centers, and they have used these weapons in the conflict.

Azerbaijan has an indisputable advantage in the numbers of aircraft and combat helicopters, but despite the much larger capacity of Azerbaijan’s air force over Armenia’s, both sides have air defense systems that make large-scale use of manned aviation costly.

Consequently, unmanned aerial vehicles have been playing a crucial role in this war. Azerbaijan has procured a diverse array of Israeli drones. Today Baku has medium-altitude, long-endurance drones, such as Hermes-900 and Heron; loitering munitions such as Orbiter 1K, SkyStriker, and Harop; and Turkish Bayraktar TB2 unmanned combat aerial vehicles. They have also repurposed old Antonov An-2 aircraft, a single engine biplane, and are using them as disposable drones. Armenia has indigenously produced drones, but, in general, these systems are vastly inferior to Israeli designs in terms of performance.

The Fighting Thus Far

The Azerbaijani offensive can be divided into several stages. During the first three days, Azerbaijani troops attempted a ground assault with armored formations, while providing fire support with artillery, drones, and loitering munitions. Armenian troops withdrew from the first line of defense in the southeast and northern regions of controlled territory, but inflicted casualties with anti-tank guided missiles and artillery on the leading Azerbaijani armor formations. Azerbaijan began attriting Armenian air defense systems, destroying 13 short-range surface-to-air systems (Osa-AKM and Strela-10), but they eschewed the use of combat aviation. Overall, the initial offensive resulted in the loss of dozens of armored vehicles, and limited gains in the south.

From the end of the third day until the beginning of the sixth day, the parties engaged in position warfare, with some progress on the Armenian side in the north, marking the second stage of the hostilities. The largest counteroffensive on the Armenian side took place on the fourth day. As Armenian armored vehicles and artillery maneuvered into the open, they found themselves relatively exposed to the use of combat aerial vehicles, loitering munitions, and drones marking targets for artillery. These Armenian units were left largely unprotected by the old air defense systems that they had available, and suffered considerable losses as a result. The loss of a total of 84 tanks thus far by Armenia, along with numerous multiple launch rocket systems and artillery systems, compared to a total of 13 to 15 air defense systems, suggests a fairly low availability of air defense relative to the size of the armored force fielded.

Day six began to show some exhaustion among both sides, but by this point, Azerbaijan had begun shelling Stepanakert, the capital of Nagorno-Karabakh, with 300 mm multiple launch rocket systems. Additionally, Azerbaijan used an Israeli-made LORA tactical missile to destroy a bridge on the way from Armenia to Karabakh. Azerbaijani forces sought to target Armenian ground lines of communication to prevent the deployment of reserves and stall counteroffensives. Armenians forces began firing against infrastructure in Azerbaijan, using BM-30 Smerch 300 mm multiple launch rocket systems to hit the airport of Ganja about 60 kilometers away from the Armenian border, and using tactical missiles as well. Both sides have been trading rocket artillery strikes since, targeting critical infrastructure, and inflicting civilian casualties, using systems that could range the entire theater of operations.

On the morning of day seven, Azerbaijan’s First, Second, and Third Army Corps (most of its units are located on the Armenian border) were reinforced by the reserves of the Fourth Corps, which protects the Absheron Peninsula and Baku. The Azerbaijani attack knocked Armenian forces from their forward positions in the north and may have temporarily seized the border settlement of Mataghis. It is unclear who possesses Mataghis at the time of this writing. Azerbaijan’s leadership has regularly reported capturing settlements which they had not in fact captured. The eighth day of the war was marked by further shelling of Stepanakert, the capital of Nagorno-Karabakh, and Armenian strikes against targets in Azerbaijan.

Much of the fighting has shifted to the south, as the war in the northern regions proved costly, but resulted in few gains that could be declared as victories by either side. Azerbaijani offensives proceeded in the direction of Jabrayil and Fuzuli, near the Iranian border. Subsequent days of fighting focused on this region, and Azerbaijani forces briefly captured Jabrayil, but were partially enveloped. They seem to control the town as of this writing, but Armenian forces hold the mountains beyond this point. This territory is relatively flat and unpopulated, making it the most likely place where Azerbaijan’s forces could make progress. Azerbaijan’s army controls a stretch of terrain in the south, recapturing territory that has long been held by Armenian forces as a buffer zone. However, this advance has also stalled, and there were also signs that several thousand Azerbaijani troops were partially surrounded in Jabrayil given the canalizing terrain.

The war has not resulted in dramatic turnovers of territory, and has proven costly for both sides, expending manpower, munitions, and materiel. It is not clear if what Azerbaijan has gained so far — a strip of land in the south largely along the Iranian border — will suffice as a political victory for Azerbaijan’s leader, Ilham Aliyev. All together Azerbaijan may have captured 2.8 percent of the territory of Artsakh. At this stage the conflict may settle into a position war of attrition, but a genuine ceasefire is not on the horizon. Azerbaijan appears to have the capacity to destroy Armenian ground forces from the air, largely thanks to its unmanned aviation, but at the end of the day, only ground forces can seize and hold terrain. Tactical successes have not yielded a notable operational or strategic victory, and Baku’s path towards achieving political objectives via the battlefield remains unclear.

Although fighting has reached Armenian-populated towns, like Hadrut, there is little evidence that Azerbaijani forces will make tremendous progress in the coming weeks based on observable performance. Armenian forces have suffered significant losses. These have been largely due to airpower, both in fixed positions (which were ill prepared against air attack) and when maneuvering for counter offensives. However, the Azerbaijani drone campaign was not a systematic suppression or destruction of Armenian air defense. Instead it appears to be an adaptation resulting from lack of progress in the early days of the fighting.

Battlefield realities will drive ceasefire negotiations. This will undoubtedly depend on their expectations of diplomatic, political, or military support from other parties such as Turkey or Russia, as well as external political pressure. Overall, Azerbaijan is much better positioned in a sustained war of attrition, and even if there is a ceasefire, Baku may re-arm and launch another offensive in some time, which will eventually exhaust Armenia’s military. Moscow has made clear that its alliance with Armenia does not extend to territories held outside the country, i.e., Nagorno-Karabakh and outer lying regions held. Consequently, Russia will not intervene unless the war becomes an existential contest.

Implications for Modern Warfare

The information war has been just as fierce as the actual war, with both sides posting daily combat footage to proclaim victories on the battlefield. Disinformation and propaganda, spread through official and unofficial accounts, have made it difficult to objectively assess the course of combat thus far. Furthermore, the relative accessibility of combat footage — whether from drones, cellphones, or cameras — paints a stylized picture of the battlefield for any analyst. They are official propaganda, and it is worth noting that on the modern battlefield, some systems have cameras or live video feeds, while many do not, distorting perceptions on combat effectiveness. A social media feed composed largely of drone video footage could lead one to believe in the dominance of such systems, even in a conflict where many casualties are still inflicted by armor, artillery, and multiple launch rocket systems. This tactical footage has led to familiar debates on the utility of tanks, the prowess of drones on the battlefield, or the proliferation of sensors.

There is a thirst for drawing lessons from contemporary conflicts that feature modern weapon systems. However, the result is often generalizing from a few cases, and at times, learning things that are not true. What can be discerned from this war is hardly revelatory. Remotely operated systems offer the utility of tactical aviation, close air support, and precision guided weapons to small nations, and to even relatively poor countries, for a cheap price. They saturate the battlefield with disposable sensors, shooters, and sensor-shooter packages in the form of loitering munitions. Notably, they enable precision artillery and strike systems to engage fixed positions, as has been seen across modern conflicts from Ukraine to Syria. Furthermore, tanks are vulnerable to counters, as they always have been, but it is unclear what other vehicles offer a better combination of firepower, protection, and maneuverability on the battlefield.

The war illustrates that in an offensive, or counter-offensive, the only thing worse than being in a heavily armored vehicle is being outside of one. If anything, the tank appears to be the most survivable vehicle, given the small warheads on drone carried munitions. These munitions often disable or mission kill the vehicle, but the crew can still survive anything other than a direct hit. Much of the hand-wringing in Western circles that comes from watching these conflicts stems from the epiphany that there is no way to avoid casualties on the modern battlefield, especially among an expensive force, replete with boutique capabilities that cannot be lost in large quantities. Furthermore, the ratios of support to maneuver units are important. Compared to forces like the Russian military, Western ground units feature poor availability of air defense and electronic warfare, and the expectations that existing air defenses or tactical aviation may be easily adapted to counter unmanned systems are probably unfounded. Armenia’s performance illustrates this problem. Drones are relatively cheap, and this military technology is diffusing much faster than cost-effective air defense or electronic warfare suitable to countering them.

That said, Azerbaijan’s unmanned air force has been operating against an opponent with incredibly dated short-range air defenses which are neither suitable nor effectively employed to defend against drones. Armenia does not have layered air defense, effective electronic warfare, or a large amount of tactical aviation. It has situated its air defense systems in relatively exposed fixed positions, in a mountainous region where air defense is even more difficult by virtue of the terrain. In truth, both sides are demonstrating tactical deficiency in their offensive and defensive tactics. While attaining some kills using optical sights, Armenia’s modernized Soviet systems (essentially technology that dates back to the early 1970s) were never meant to engage combinations of small drones, loitering munitions, precision artillery, or unmanned combat aerial vehicle systems. More advanced air defense capabilities like Tor-M2s are few, and have been intentionally held in reserve, although Azerbaijan has been reticent to use its fixed wing or rotary aviation. Armenia’s older S-300PS systems appear to have had no role in the conflict, and some launchers may have been destroyed early on, having never even been deployed.

The lessons from this conflict are consistent with those of other wars in the latter 20th century: It is much better to have a smaller ground force that is well defended from the air, than a vast armored force that is completely exposed to sensors and airpower from above. Well prepared defenses, if insufficiently protected or camouflaged from the air — which is increasingly difficult — are naturally vulnerable. The diffusion of remotely operated systems will outpace that of air defenses or specialized counter-drone systems, rendering older generations of air defense largely obsolete. Drones and loitering munitions will be, for some time, cheaper to acquire than the requisite defenses. And one can distribute forces, but they should be concentrated for assaults. There is no way getting around canalizing terrain, at least not until the battlefield features hover tanks. That tanks are vulnerable to anti-tank weapons should come as no surprise, but other vehicles, which trade survivability for maneuverability, seem to fare no better against anti-tank guided missiles. Vulnerable or not, it is unclear what other vehicle can achieve the tank’s mission on the battlefield.

Finally, fetishizing combat video feeds plays to a Western intellectual preference for the tactical, and system on system evaluations, while ignoring the basic fact that Azerbaijan has not been able to attain a significant operational success. This perhaps is the most important lesson of the conflict: Tactical successes, which may appear impressive, can fail to add up to an operational breakthrough. In such cases, military strategy turns to the old familiar: a battle of attrition.

Correction: A previous version of this article stated, “the Armenian drone campaign was not a systematic suppression or destruction of Armenian air defense.” That was incorrect. It was an Azerbaijani drone campaign. Also, a previous version stated that the “dispute is over a majority Armenian region that had autonomy within the Soviet Union.” The article has been updated to say that the region “had autonomy within the Azerbaijan Soviet Socialist Republic of the Soviet Union.”
