A few thoughts on the current course of the war, and some impressions after a recent visit to Ukraine with several colleagues from the mil analysis community, including areas near the front in Kherson. /1
The general sense one gets is that Ukraine is winning the war & morale is high, but like any military operation, you see friction up close that you can’t from a distance. A fair bit of the UA effort is ground up, based on horizontal linkages, volunteers, apps, etc. 2/
Russia’s military appears at its most vulnerable going into the winter, but UA has seen some modest impact from RU mobilization. Troops are being deployed to try and stabilize Russian lines, and increase force density relative to terrain. 3/
The situation in Kherson is clear as mud. Russian forces seemed to withdraw from some parts, evacuated, and drew down, but also reinforced with mobilized personnel. The fighting there is difficult. Despite constrained supply, Russian forces do not appear to be out of ammo. 4/
I think this is a fog of war issue right now, with contradictory indicators, but to me the preponderance of evidence points to a Russian decision to steadily retreat from the right river bank and avoid being cut off there, while also trying to exact a high cost. 5/
UA folks I spoke to seemed optimistic they can press Russia out of Kherson (west of the river) by the end of the year. There are outstanding questions about the Khakovka dam, and whether RU might sabotage it upon withdrawal. This issue is more salient than talk of RDDs. 6/
Still, it remains unclear whether RU intends to fight for Kherson city, perhaps using more expendable or mobilized units while preserving better troops. I'm skeptical RU will abandon all positions on that side without being forcibly pressed out, but could be wrong on this. 7/
Forcing a Russian retreat from Kherson’s right bank will bring UA systems within range of some ground lines of communication from Crimea. But, it will also give RU forces a large natural barrier, less terrain to defend, and a higher force density to terrain ratio. 8/
Overall, it seems unlikely that the war will die down over the winter, even if some months make offensive operations challenging. UA will likely leverage its advantage in range and precision to attrit the Russian military over this period. 9/
Strikes across Ukraine are leading to blackouts and electricity conservation. UA is resolving these blackouts quickly, and if anything the bombardment campaign bolsters resolve, but over time the challenges from these strikes could mount, straining equipment and ADS ammo. 10/
I’ve been dismissive of the Belarus vector, despite recent RU deployments there. But the situation merits tracking over the coming months if numbers of Russian troops grow and they are provided heavy equipment. 11/
Mobilization, and its potential downstream effect 3-4 months from now introduces a degree of uncertainty. It could extend the war, or make future UA offensives more costly, but I think UA is preparing for a range of possibilities depending on what mobilization yields. 12/
On mobilization I largely hold to the thoughts in this earlier thread. It seems RU is taking a staggered approach, throwing some mobilized personnel with little training to stabilize lines, but holding many back to reconstitute units or form reserves.
RU strategy appears to be focused on defense over the winter, hoping that mobilization can rebuild their forces. If the pressure lets up they will use the time to get more equipment out of storage (including from Belarus) & potentially ammo from sources like DPRK. 14/
In the east RU forces appear desperate to hold the Troitske-Svatove-Kreminna line and are trying to dig in for the winter. Here a UA breakout could prove significant. In general it seems RU approach is to try and fix a defensible line and hope to maintain over the winter. 15/
UA objectives are likely to prevent Russian force reconstitution over the winter, generate additional forces in the interim (which requires more equipment), and acquire air defenses to reduce the threat from the Russian strike campaign against critical infrastructure. 16/

An update on the war following a recent trip. The situation has improved compared with Fall 2024. Russian offensive momentum slowed significantly over the winter, though it is premature to claim that the front has stabilized, especially following AFU withdrawal in Kursk. /1
Russian advances were stalled for three reasons: materiel exhaustion from losses in the fall, effective Ukrainian adaptation to how Russian forces were prosecuting offensive operations, and winter weather conditions which affected the pace of operations. 2/
This dynamic may not hold as we get further into the spring. Russian forces appear to be regrouping for renewed offensive operations. Ukrainian forces have improved tactically at countering how RF fight, employing UAS to compensate for a deficit of manpower at the front. 3/
The suspension of U.S. assistance for Ukraine is a very unfortunate and significant development, but it may not have immediate impact. Ukraine is far less dependent on the U.S. for day to day battlefield needs in 2025, than it was in earlier periods of the war. 1/
Ukraine’s current approach to defensive operations combines mines, strike drones, and traditional artillery fires to attrit Russian forces at 0-30km. Most of the casualties are now inflicted with mines, and drones, which are produced in Ukraine. 2/
Traditional artillery fires are less relevant at the moment, and there is a relative parity between the two sides. In combination with munitions recently delivered by the U.S. in recent months, which frontloaded supplies, Europeans could sustain Ukraine through this year. 3/
Brief thoughts on a European force for Ukraine. I think there is a degree of requirements paralysis. It doesn’t have to be hundreds of thousands of troops, or cover a 1200km contact line. Where it is deployed, and in what role, is more important than the overall size. 1/
The force does not need to be everywhere. It needs to be in country with battalions deployed on maybe 4 operational directions, and sufficient mobility to redeploy as necessary along the front. This can be as few as 3 brigades or their equivalents. 2/
A future Russian attack is going to come along a few predictable directions, and today most of the fighting is concentrated typically along 4-5 sectors of the front at a time. 3/
A long thread on the war and the current situation. Although the worst-case scenarios didn’t materialize in 2024, it was the most difficult period since spring 2022. There were positive developments, and bright spots, but the current trajectory is negative. 1/
First, a brief retrospective. Last winter things looked bleak. Ukraine was dealing with a deficit of manpower, low supplies of ammunition, and was only starting to establish a network of fortifications. Russia held the initiative, and the materiel advantage going into 2024. 2/
Even though Avdiivka fell, by summer it became clear that a collapse of UA frontlines was unlikely. Russia’s Kharkiv offensive was unsuccessful, and they couldn’t capitalize on the strain imposed. Early results from UA mobilization in June-July seemed positive. 3/
Sometimes oft repeated numbers need revisiting. One example is Russian artillery fire rates. These have generally been overestimated going back to 2022, along with ammo consumption rates, with sensational 60k per day figures. A short thread. 1/
First, what are we counting? The numbers given out are typically for main caliber artillery types: 152mm, 122mm, MLRS (300, 220, 122), and 120mm mortars. This figure is not inclusive of smaller infantry mortars, anti-tank guns, tanks used indirect fire roles, etc. 2/
Russian fire rates for 2022 were probably in the 15,000-20,000 range. Likely ~18,000 (see forthcoming podcast discussion on this). There’s little evidence that Russian fires reached 60,000 per day in 2022. The peaks were likely double the figure above, at 35,000-40,000. 3/
Thoughts following a recent field study in Ukraine. Ukraine faces difficult months of fighting ahead, but the situation at the front is better than it was this spring. More worrisome is the state of Ukraine’s air defense, and the damage from Russian strikes to the power grid. 1/
Ukraine’s manpower, fortifications, and ammunition situation is steadily improving. Russian forces are advancing in Donetsk, and likely to make further gains, but they have not been able to exploit the Kharkiv offensive into a major breakthrough. 2/
The Kharkiv front has stabilized, with the overall correlation of forces not favorable to Moscow there. Russian operations are focused on the following directions: Chasiv Yar, Toretsk, Ocheretyne-Pokrovsk, and to a lesser extent Kupyansk. 3/
