MIL Weekly — Russia-Ukraine War
MIL Weekly — September 11, 2026
The biggest change in this week’s MK5-MIL assessment isn’t on the front line. Ukraine’s deep-strike campaign is reaching farther into Russia and producing increasingly measurable economic effects, while newly disclosed Russian activity around NATO infrastructure strengthens the case that Moscow’s gray-zone campaign is becoming persistent.
The conventional battlefield remains comparatively stable. Russia continues offensive pressure in eastern Ukraine, but there is still no evidence of the operational breakthrough that would radically change the military or diplomatic balance.
This week’s assessment also adds MK5’s calibration ledger, source-validation layer, trend tracking, and weather module.
What changed this week
Four indicators stand out.
Russian breakthrough risk: → Stable
Russian forces remain on the offensive in Donetsk and other sectors, but neither Russian nor Ukrainian forces made confirmed advances on September 10, according to the Institute for the Study of War. Ukrainian drone operations are also reportedly slowing Russian advances around Dobropillya.

Negotiation activity: → High, but stalled
U.S. envoys Steve Witkoff and Jared Kushner met Vladimir Putin in Moscow on September 5 and subsequently engaged Kyiv. The Kremlin characterized the discussions as useful but announced no breakthrough.
President Volodymyr Zelensky said September 10 that trilateral negotiations would not take place before Russia’s September 18–20 parliamentary elections. U.S.-Ukrainian discussions are continuing, including possible narrower agreements involving energy and grain.
Ukrainian deep-strike pressure: ↑ Rising
Ukraine has extended its long-range campaign dramatically. Ukrainian forces reported striking Russian gas-processing facilities nearly 3,000 kilometers from the Ukrainian border, which would represent Ukraine’s deepest long-range drone attack of the war.

More importantly, there is now stronger evidence that the campaign is producing measurable economic effects. The International Energy Agency lowered its Russian oil-production forecasts again on September 11 and explicitly cited continued Ukrainian attacks on Russian energy infrastructure. It estimated Russian crude production at 8.36 million barrels per day in August, 940,000 barrels per day below January.
Russian gray-zone activity against NATO: ↑ Rising
Reuters reported September 10 that Britain, Norway, and the United States disrupted a Russian undersea operation near Svalbard earlier this year involving infrastructure linking the archipelago with mainland Norway. The operation caused no damage, but Western officials assessed that Russia’s specialized GUGI undersea unit was practicing activity associated with disrupting subsea infrastructure.
That disclosure joins more overt cases. NATO now publicly describes the Leipzig airport incident as a Russian hybrid attack, and Secretary General Mark Rutte said September 10 that the alliance is responding by strengthening infrastructure protection and imposing costs on Russian activities.
Battlefield
Russia’s main strategic problem remains unchanged. It can maintain pressure across a very long front, but it has not converted that pressure into a decisive operational breakthrough.
Russia continues offensive operations around Kupyansk, Kostyantynivka, Dobropillya, Hulyaipole, northern Kharkiv, and other sectors. ISW found no confirmed Russian advances on September 10 despite Russian claims of additional territorial gains.
Institute for the Study of War
The Donetsk campaign remains the most important area to watch. Reuters reported September 8 that Russia is increasingly pressing toward Sloviansk and Kramatorsk, while Ukraine has reorganized command responsibilities in preparation for potentially intense fighting there.
MIL therefore continues to classify the war as an attritional contest rather than a developing Russian breakthrough.
Trend: → Stable
Confidence: High
Diplomacy
The diplomatic channel is active enough that MIL still expects another serious negotiating round.
What has weakened is the case for an imminent ceasefire.
Putin’s September 5 meeting with Witkoff and Kushner lasted more than three hours but produced no announced agreement. Trump subsequently said Putin wanted a deal, while intelligence officials cited by Reuters remained skeptical that Moscow was genuinely prepared to end the war in the short term.
Zelensky’s statement that trilateral negotiations will wait until after Russia’s September 20 election gives the model a useful near-term checkpoint.
Current MIL probabilities
- Substantive negotiations within 1–2 months: 75–85% →
- Limited or sector-specific agreement: 25–35% →
- Broad ceasefire covering most combat: 15–25% ↓
- Durable political settlement: under 15% →
MIL considers negotiations likely because all three principal governments are actively engaged in diplomacy. It considers peace much less likely because the underlying territorial and security disputes remain unresolved.
Ukrainian deep strikes
This is the strongest upward-moving indicator in this week’s report.
Ukraine is no longer merely demonstrating that it can hit targets inside Russia. Its campaign is forcing changes in logistics, energy production, air defense deployment, business behavior, and Russian civilian perceptions of the war.
ISW reported that Ukraine struck major gas-processing facilities nearly 3,000 kilometers from its border, Black Sea and Caspian Sea port targets, Russian military infrastructure in occupied Ukraine, and numerous air-defense and drone facilities during August.
Institute for the Study of War
Ukraine has also increasingly attacked Russian commercial logistics infrastructure. Reuters reported September 11 that recent strikes have damaged warehouse networks used by major Russian online retailers, while the war’s effects are becoming increasingly visible to Russians ahead of the parliamentary election.
The strongest independent evidence comes from the energy sector.
The IEA cut its 2026 Russian crude-production forecast by another 125,000 barrels per day and its 2027 forecast by 235,000 barrels per day, citing Ukrainian attacks on energy infrastructure. Russia no longer publishes detailed official oil-output statistics, so estimates from organizations including the IEA and OPEC differ somewhat, but both indicate a substantial August decline.
MIL therefore upgrades Ukraine’s deep-strike campaign from a significant military pressure mechanism to a strategically consequential pressure mechanism.
That does not mean the strikes alone can force Russia to end the war. It means the campaign is increasingly altering the cost equation Moscow faces.
Trend: ↑ Strongly rising
Confidence: High that effects are material; medium on the precise scale of physical damage
NATO escalation and the gray zone
MIL continues to separate two very different risks.
A deliberate Russian conventional attack against NATO would create enormous escalation risk and remains unlikely.
Covert or deniable Russian operations against NATO countries are another matter.
NATO itself says Russia is conducting aggressive hybrid actions involving critical infrastructure sabotage, violence, cyber activity, electronic interference, provocations, and political influence.
The newly disclosed Svalbard episode adds a particularly important indicator because the reported operation involved a specialized Russian military organization and strategically significant subsea infrastructure. No cable was damaged, making this an example of gray-zone preparation or probing rather than an overt armed attack.
Polish Prime Minister Donald Tusk separately said September 10 that Polish and Ukrainian security services had prevented a threat against a border crossing and that Poland expects Russia to target crossings used to sustain Ukraine’s economy and logistics.
NATO nevertheless said as recently as August 30 that it saw no imminent threat of a direct Russian attack against the alliance.
MIL probabilities
- Deliberate conventional Russian attack on NATO in the next several months: below 10% →
- Continued Russian sabotage, cyber operations, covert action, infrastructure interference, or proxy activity against NATO countries: 75–85% ↑
The second probability should not be interpreted as an 80% chance of NATO-Russia war. It represents activity specifically designed to remain below that threshold.
MK-WX weather check
Weather is relevant this week, but it is not yet a dominant battlefield variable.
Forecasts around Sloviansk and the northern Donetsk battlefield show generally warm and relatively dry conditions through the weekend, with little expected precipitation before a possible increase in clouds and light rain early next week.
That means eastern Ukraine has not yet entered the sustained wet-weather conditions associated with severe autumn mobility problems.
Dry ground generally favors movement compared with the later mud season, although wind, cloud cover, and localized weather can still affect drone reconnaissance and operations. Reuters notes that Ukrainian commanders and analysts are already watching the September-to-October weather transition because worsening conditions can reduce some drone effectiveness and potentially alter the relative usefulness of mechanized forces.
WX impact this week: Low
Trend to watch: ↑ Seasonal importance increasing
MIL should therefore continue monitoring weather but should not use it to explain this week’s battlefield stagnation.
CL calibration check
This week’s report can now score several predictions from the previous MIL assessment.
Russian operational breakthrough remains unlikely — HIT
Russia continued attacking, but the latest independently assessed frontline data still shows limited movement rather than the decisive breakthrough MIL regarded as unlikely.
Renewed negotiations remain likely — PARTIAL HIT
High-level U.S.-Russian and U.S.-Ukrainian diplomacy occurred, validating the forecast that negotiations would remain active. A trilateral round has not yet occurred, so the stronger version of the prediction remains unresolved.
Limited ceasefire arrangement — UNRESOLVED / SLIGHTLY WEAKER
No meaningful ceasefire emerged this week, and Russian and Ukrainian long-range attacks instead intensified. The original probability was low enough that this is not yet a failed forecast, but the near-term probability should edge downward.
Direct Russian attack on NATO remains unlikely — HIT SO FAR
No conventional Russia-NATO attack occurred, and NATO continues to say it sees no imminent direct threat.
Russian gray-zone activity remains likely — HIT, WITH STRONGER EVIDENCE
This was MIL’s clearest successful warning. New reporting concerning Svalbard and Polish border infrastructure, combined with NATO’s attribution of the Leipzig incident, strengthens rather than weakens the original assessment.
Ukrainian deep strikes will become strategically consequential — HIT
The IEA’s revised Russian production forecasts provide unusually strong independent evidence that the campaign has progressed beyond isolated tactical disruption.
Calibration result
MIL’s strongest performance this week was identifying gray-zone escalation and deep strikes as more likely to change the strategic environment than rapid territorial movement.
The weakest part of the model remains ceasefire timing. Diplomatic activity is comparatively easy to detect; translating that activity into an agreement remains much harder to forecast.
CL should therefore preserve high confidence in the negotiation-activity indicator while applying a larger uncertainty penalty when converting negotiations into ceasefire probabilities.
Source check
This week’s evidence is unusually strong in several areas.
High-confidence evidence includes the IEA’s independent production estimates, Reuters reporting based on multiple government and intelligence sources, NATO’s public statements regarding Russian hybrid activity, and independently verified imagery or video.
Medium-confidence evidence includes ISW battlefield assessments based on geolocated material and cross-checked Russian and Ukrainian reporting. These are useful for determining whether territorial claims are supported, but battlefield information remains incomplete.
Lower-confidence evidence includes individual Russian or Ukrainian military claims about strike damage, casualties, interceptions, encirclements, or equipment destruction that lack independent confirmation.
For that reason, MIL does not treat every reported strike as a successful strike or every claimed territorial gain as an actual gain.
The Novy Urengoy and Purovsky attacks are a good example. Ukrainian authorities report that the facilities were hit at unprecedented range, making the claimed reach significant, but the precise amount of damage should remain provisional until stronger independent evidence is available.

MIL outlook
The most likely path remains continued warfare accompanied by intermittent diplomacy.
Russia still has the ability to sustain substantial offensive pressure and an intensive long-range strike campaign, but it has not demonstrated the ability to force a rapid battlefield decision.
Ukraine has likewise not shown that its deep strikes can independently compel Moscow to stop fighting. What has changed is the amount of credible evidence that those attacks are imposing military and economic costs far behind the battlefield.
At the same time, Russia’s confrontation with NATO increasingly extends beyond Ukraine through covert action, infrastructure threats, cyber operations, and other activity intentionally kept below the threshold of conventional war.
That combination reinforces MIL’s dominant scenario.
The conflict is increasingly becoming a contest of coercive bargaining. Russia is trying to increase the cost of Ukrainian resistance. Ukraine is increasing the cost of continuing the war for Russia. NATO is supporting Ukraine while trying to contain Russian activity below the level that would trigger a direct military confrontation.
Negotiations are therefore occurring alongside escalation rather than replacing it.
Bottom line
MIL sees no decisive battlefield turn this week.
The meaningful changes are happening farther from the trenches: Ukrainian strikes are producing increasingly measurable effects inside Russia, Russia’s gray-zone confrontation with NATO is becoming better documented, and diplomacy remains active without yet producing meaningful military restraint.
CL says the model’s battlefield, deep-strike, and gray-zone forecasts are performing reasonably well. The ceasefire forecast deserves more skepticism.
WX adds one final constraint: weather is not responsible for the current battlefield stalemate, but the approaching autumn transition could begin changing operational conditions within the next several weeks.
For now, the war remains on the path MIL has favored for several weeks — prolonged fighting, expanding pressure away from the front, and negotiations conducted from inside the conflict rather than after it.
