A few thoughts on the current course of the war. Although winter has proven a transitional phase, with both sides focusing on force reconstitution and positional fighting. The outlines of the coming months & likely offensive operations are steadily becoming clearer. Thread. 1/
After Kharkiv & Kherson, the Russian military was at its most vulnerable going into the winter. Mobilization helped stabilize Russian lines, raise manning levels, and establish reserves. Consequently, Ukraine no longer enjoys a significant manpower advantage. 2/
RU adopted a largely defensive strategy under Surovikin focused on force reconstitution, entrenchment, and a strike campaign against UA critical infrastructure. Bakhmut was not an exception, largely fought by Wagner PMCs from RU prison system. 3/
When mobilization was launched I was wary of the uncertainty it introduced, and its potential to significantly extend the war. At the time, a reasonable timeline to assess what RU could make of mobilized personnel was 3-4 months. 4/
It’s fair to say since October RU has likely doubled the force deployed in Ukraine, and significantly reduced the length of the front being defended after retreating from Kherson. Force density has therefore increased relative to territory being occupied. 5/
The UA official figure on RU forces (320k) strikes me as a bit high, but 250k+ is probably fair. RU may have another 150,000 mobilized personnel still in Russia, not deployed. However, readiness level and quality of these units remains unclear. 6/ washingtonpost.com/world/2023/01/…
How strong the Russian defensive lines are in practice has yet to be truly tested. RU has manpower in quantity now & continues to pull equipment out of storage, but force quality appears relatively low. This limits offensive potential & force employment options. 7/
In brief, mobilized units in aggregate do not appear as poor as anecdotes might lead one to believe, and RU can likely offer a stubborn defense, but are less liable to be suitable for offensive operations and represent weak replacements for lost regulars. 8/
RU still depends on airborne and naval infantry at key points along the front as the reserve, for counter attacks, and the main assault force. These units backstop mobilized personnel, but seem to have lost some of their offensive edge due to replacements. 9/
After Soledar, the situation around Bakhmut increasingly looks precarious for UA, and I wouldn't be surprised if they ultimately withdraw from the city. However, UA has strong defensive lines outside Slovyansk/Kramatorsk while RU looks ill positioned to sustain momentum. 10/
Bakhmut is geographically important, but has developed a degree of sunk cost mentality for both sides. A fair bit of UA defense there seems to consist of TDF, NG, and foreign legion units suggesting UA is trying to manage the impact of attrition on its force availability. 11/
Having lost Izyum and Lyman, RU has no supporting axis of attack into Donetsk from the north, nor have their forces been able to make breakthroughs in the south of Donetsk. Hence gaining Bakhmut, in my view, offers opportunities for RU that they're not positioned to exploit. 12/
Since June I've been skeptical that RU could make break through to Slovyansk/Kramatorsk. They're still at Bakhmut 7 months later. That said, UA has ceded much of the initiative since October in Donetsk, and recently Luhansk. 13/
UA had made progress at Kreminna and Svatove, though now under counter-attack by the VDV's 76th GAAD. Kreminna is a gateway to Rubizhne. For UA, a breakthrough the Svatove-Kreminna line can eventually lead to the RU logistical hub of Starobilsk. 14/
Hence the battle for Kreminna is arguably more significant than Bakhmut. That said there’s been a fair amount of reorganization in RU logistics, and adaptation. I think the conversation on RU logistical problems in general suffers from too much anecdotalism & received wisdom. 15/
In my view Donbas remains the primary goal of RU mil operations, hence RU offensives are likely to focus on seizing this territory. I’m skeptical of claims that Russian forces will attempt a much larger scope offensive involving the cities of Kharkiv, Sumy, Kyiv, etc. 16/
I would consider a Russian attempt to advance Kreminna -> Lyman as likely, also Kupyansk, along with attacks across southern Donetsk, i.e. at Vuhledar. The fighting for Vuhledar, along with attacks elsewhere, suggest that this offensive has already begun in practice. 17/
RU’s better forces and kit, VDV and NI, have been trying to unsuccessfully press UA forces out of Vuhledar. The 155th couldn’t do it under Surovikin at Pavlivka in November, so its unsurprising Gerasimov taking over has done nothing to improve RU offensive performance. 18/
With respect to Belarus, a repeat assault on Kyiv makes little sense. An operation to sever supply lines in the west, or to seize the nuclear powerplant by Rivne, may be more feasible, but this would require a much larger force than what RU currently has deployed in Belarus. 19/
How large of a RU offensive to expect is unclear, but I suspect it may prove underwhelming, focused largely on the Donbas. RU may not need another large mobilization wave, and instead could keep mobilization quietly rolling at a sustainable rate. 20/
Arguably, UA is better served absorbing the RU attack & exhausting RU offensive potential, then taking the initiative later this spring. Having expended ammunition, better troops, and equipment it could leave RU defense overall weaker. 21/
But, I suspect Kyiv does not believe that time is on Ukraine's side. Wary of Russian entrenchment and seeking to avoid the perception of a stalemate, UA is likely to move sooner than later. That's been the trend thus far. 22/
Western equipment may not arrive in time to be relevant for a UA offensive, but more significant in that it will allow UA to launch operations this spring knowing they have replacements secured. Hence the likely losses entailed won't leave UA vulnerable later this year. 23/
In general UA is still advantaged going into 2023, backed by countries with much greater GDP and defense industrial capacity. However, that depends on sustainability of external material support, and in the end potential is not predictive of outcomes. 24/
The challenge is providing Ukraine with sufficient relative advantage to enable offensive operations under changed conditions in 2023. Unlikely to be solved by any single capability, but through a combination of means, organizational adaptations, and changes in force employment.
Adding a comment in response to questions on mobilization. My sense is RU is preparing a follow on mobilization wave, and we will see it eventually, but doubt it will be for this offensive, or at ~500k. I'm skeptical they can equip or sustain another wave at this stage.

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/
