The Hudson Institute: Ukraine reinforces defense of Pokrovsk, attacks Russian oil refinery

Hudson Institute

Ukraine Military Situation Report | August 20

Below Hudson Senior Fellow Can Kasapoğlu offers a military situation report about the Russia-Ukraine War.

Executive Summary

— Ukraine’s deep-strike campaign: Ukraine struck the Volgograd refinery, which produces almost 5 percent of Russia’s oil output. The strike forced the facility to halt operations.

— Battlefield assessment: The Ukrainian military rushed detachments from elite combat formations to the critical Pokrovsk sector to shore up its weakened lines of defense.

— Russia’s air war: Russian Shahed drone attacks hit a record high in July. It fired an average of 103 drones at Ukraine per day.

1. Battlefield Assessment

Last week the operational tempo of the conflict spiked. The Ukrainian General Staff noted that its forces had participated in as many as 130 combat engagements on some days, with more than 30 percent of such efforts taking place in the Pokrovsk sector.

Despite the headlines generated by the Russia–United States summit in Alaska, Russian units did not slow their efforts to capture the city. To repel Russia’s push into the critical stronghold, the Ukrainian military has reallocated detachments from combat formations in other sectors. Most recently, Ukrainian command has moved troops from the 25th Airborne Brigade, the 79th, 82nd, and 92nd Air Assault Brigades, the Security Service of Ukraine (SBU), the Azov Brigade, and the 38th Marine Brigade into the sector. The 79th Air Assault Brigade has already managed to recapture territory and seize Zolotyi Kolodyaz, a small town 30 miles from Pokrovsk.

This success is a ray of hope for Ukraine and its supporters. But Ukraine’s manpower shortage means its forces still face major disadvantages in force-on-force and force-to-terrain ratios. The newly deployed Ukrainian units are likely to serve only as a temporary salve. Kyiv will continue to struggle to defend the Pokrovsk sector, especially as Russia has breached sections of the front near Dobropillya, a small city north of Pokrovsk.

No drastic territorial changes occurred elsewhere. Intense fighting continued, as it has in recent weeks, near Lyman, Kupiansk, Toretsk, and Orikhiv.

Away from the front lines, Ukraine’s Main Directorate of Intelligence (GUR) released the technical specifications of a new delta-wing drone that Russian units have been using in combat. The unmanned aerial vehicle (UAV), probably a variant of Russia’s Italmas drone, shares a design philosophy with the Shahed, though with a shorter range. Over half of the components in the new drone originated in China, including communications modules, memory chips, and other critical parts. In recent months Ukrainian analysts have found an increasing number of Chinese-made components in Russian weapons systems, a trend this report will monitor.

On the offensive side, Kyiv continued to hit critical petrochemical facilities deep inside Russia. Last week it struck the Volgograd refinery, a facility responsible for 15 million tons of annual oil production, or roughly 5 percent of Russia’s overall output. Ukraine’s strikes forced the refinery to halt its processing operations.

2. Russian Drone Attacks Reach a Record Monthly High

Russian drone attacks continue to menace Ukraine’s cities and pose a significant threat to both Ukraine and, potentially, the North Atlantic Treaty Organization (NATO).

Russia launched more drones at Ukraine in July 2025 than it has in any other month of the conflict, firing at least one Shahed salvo each day. In total, the Kremlin’s forces launched around 6,200 UAVs, or a daily average of 103. This marks an increase of almost 20 percent from June. Most of these munitions were Russian-Iranian Shahed variants aimed at Ukrainian civilians. The Ukrainian military intercepted 88 percent of Russia’s attacks, using both kinetic means and electronic warfare measures.

There are two main reasons Russia has increased its long-range attacks. First, as this report has covered thoroughly, Moscow has been expanding the Russian-Iranian drone plant in Tatarstan and establishing new production facilities. The Kremlin has also initiated programs such as Alabuga Start to recruit impoverished young workers from Africa and other parts of the developing world.

Second, imagery intelligence indicates that Russia is using new launch positions and increasing the number of facilities it uses to store munitions. Given these trends, Russia could achieve 10,000 monthly Shahed launches before the end of the year.

Forced displacement represents one of the most pressing humanitarian issues of our time. Individuals and families, torn from the fabric of their communities, find themselves navigating a world of uncertainty, often without basic necessities or a clear path to safety. There are currently some 110 million forced displaced, and this number is growing by 10 million each year!

At the heart of this crisis are the political triggers. Armed conflicts, ethnic or religious persecutions, and systemic human rights abuses force millions to flee their homes in terror. Many are displaced within their own national boundaries, while others seek asylum abroad. If these factors change as a result of political shifts at home or the pressures from abroad, they can return to their homes. Forced displacement is thus different from environmentally driven displacement, as victims of climate change may never be able to return to their homes.

The ramifications of any sort of displacement are profound, not just for those directly affected, but also for host communities and countries. Overburdened infrastructures, socio-economic strains, and cultural tensions can arise, necessitating comprehensive strategies to foster harmony and integration. Yet the root causes of forced displacement can be remedied with a concerted focus by local players and international diplomacy.

Organizations like Refugees International play a crucial role in this arena, advocating for the rights and needs of the displaced, conducting on-the-ground assessments, and influencing policymakers to take informed actions. Their relentless work underscores the gravity of the situation and the urgency ofinternational cooperation. But they, too, are overwhelmed by the rapid expansion of the crisis.

International Humanitarian Law (IHL), with its core principles centered on the protection of civilians during conflicts, plays a pivotal role in this discourse. Yet, despite clear legal frameworks, compliance remains
inconsistent. This initiative emphasizes the importance of upholding and reinforcing these international standards.

It’s not just about recognizing the problem; it’s about active engagement. We urge governments, organizations, and individuals to prioritize the rights and needs of the forced displaced. Through collective efforts, informed policies, and sustained advocacy, we can shift the narrative from passive acknowledgment to proactive intervention.
