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/

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/

Some brief thoughts following a recent field study trip to Ukraine. The current situation is difficult, but UA is working to stabilize the front. Much depends on whether the US provides support, and UA effectively addresses its manpower issues in the coming months. 1/
The main challenges are manpower, fortifications, and ammunition. These are interrelated problems. There is also the issue of sustainment, which needs to shift towards localization of maintenance, and spare parts production for a diverse park of Western equipment. 2/

A few issues with that top line casualty number released, given it includes losses from convicts, and LDNR. On top of that a significant % are also mobilized personnel and contracted recruits. The total number cannot be applied to the original force in a meaningful way. 1/
Given prior estimates the range could be 270-315k on total casualties. It is fair to say the Russian army which existed on Feb 2022 has lost much of its original personnel, and ground force equipment, but the initial invasion force itself had sizable numbers of mobilized LDNR.

A few thoughts on DPICM. Providing cluster munitions to Ukraine, at this stage, could have a significant impact beyond what other capabilities might achieve. Despite the drawbacks, unlocking this stockpile has important implications for the course of Ukraine's offensive. 1/
Ukraine's offensive is limited by the artillery ammunition available. The US, and other countries, provided a significant amount for this operation. Much of this was borrowed from South Korea. Without this ammunition it is difficult to imagine this offensive taking place. 2/

A few thoughts on Prigozhin's armed insurrection/mutiny/rebellion. For now it appears over. Wagner seems to be standing down, and leaving Rostov for LNR. Prigozhin launched a mutiny that ultimately challenged Putin’s power, and the system. Thread. 1/
This was not a traditional coup, but with Putin’s video and FSB statements it became a challenge that would reveal the extent of brittleness in the regime. It wasn’t a good showing for Russian state capacity or competence to respond to this kind of challenge. 2/

A few thoughts on the dam’s destruction and its implications for Ukraine’s offensive. In brief, I doubt it will have a significant impact on UA mil operations. The Khakovka dam is at least 100 miles from where much of the activity might take place at its closest point.
A Ukrainian cross-river operation in southern Kherson, below the dam, was always a risky and therefore low-probability prospect. There is no evidence that such an operation was under way, or would have necessarily been a part of the UA offensive plans.

Highly recommend this article. Objective insights based on in country experience. It’s very useful to have other researchers, trainers, and those doing field work compare their observations. warontherocks.com/2023/06/what-t…
The way to read this is not as a list of problems or challenges, but as an honest portrayal of a force in transition that’s done remarkably well on the battlefield and continues to evolve. UA is managing attrition, and reconstitution many modern militaries have not experienced.

I want to highlight this important article from @EvansRyan202. Presently, US policy is optimized to not learn, or to learn the wrong lessons from this war. Missing access & information that could best inform objective analysis and lessons learned. 1/ warontherocks.com/2023/04/bind-u…
Over a year into this war there seems to be little to no institutionalized effort. No observer groups. Folks go on self-initiative to study, observe, learn the history and gain access in a personal or informal capacity. There is very little support. 2/

A few thoughts on the current course of the war, Russia’s winter offensive, battle of Bakhmut, and how this phase might affect the coming months. Also check out the WOTR podcast episode below that covers some of this. Thread. 1/ warontherocks.com/2023/04/russia…
The Russian offensive in the Donbas has not yet ended, but it has weakened in pace of operations and intensity. Having achieved little, Russian forces are probably preparing to shift to a defensive posture in anticipation of a Ukrainian offensive. 2/

A few thoughts on the Russian winter offensive, which began 3+ weeks ago, and has so far yielded little progress for RU forces. Poor force quality, loss of junior officers, ammunition, and equipment constraints limit Russian offensive potential. Thread. 1/
The RU offensive consists of about 5-6 axes of attack focused on the Donbas. Rather than a major push along one part of the front, it is instead a series of distributed battles running north-south from Luhansk, to Bakhmut, and southern Donetsk. 2/

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/

Good thread by @Tatarigami_UA, but important to parse questions of logistics disruption & RU adjustment, with assessments of fire rate, available stocks, and production rates. Several factors can be relevant, making it difficult to discern which is more causal. 1/
So, are we conflating Russian logistics disruption with RU running out of ammo? My sense is that RU adjustment to logistics disruption has probably been more successful than commonly discussed, but that ammo depletion remains an important factor to watch for 2023. 2/

Good piece by Jack. I find the tank discussion somewhat talismanic, but agree that it represents an important political decision point on whether to take the better kit from current fleets to support UA, as opposed to relying on older equipment in storage. 1/
That said, IFVs are probably more important in what they offer UA overall. ADS, arty, barrels, and ammunition, remain the more significant issues. Tanks are often being used in an indirect fire role, though that could be particularly characteristic of fighting over the winter. 2/

Understand US is trying to find ways to improve outcomes and reduce UA dependence on high rates of arty fire. Less attrition, more maneuver. Training to do combined arms at company/battalion level is good in and of itself, but it won’t necessarily solve this problem. 1/
I have no doubt UA can learn combined arms maneuver, and saw elements of this at Kharkiv. However, without USAF air superiority, US logistics, C4ISR, etc it’s a bit hard to ‘fight like Americans.’ How well would we do without airpower? 2/

There's a lot of goodness in this piece by Steve Biddle. It's balanced, and well written, pouring cold water over some of the tech fetishism, and tendentious takes that have proliferated since this war began. A few comments. 1/ warontherocks.com/2022/11/ukrain…
From my point of view most technology is offense-defense agnostic, and this is largely a moribund lens for viewing war. I agree with Biddle that force employment is much more deterministic, but I would add force design, which has a structural effect on employment. 2/

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/

Recommend this NYT article. Highlights that nuclear use is ultimately a political decision, but the military has its own views, considerations, and potential courses of action it might recommend.

A few incomplete thoughts on the question of mobilization. It won't solve many of the RU military's challenges in this war, but it could alter the dynamic. Fair to say that these are uncharted waters, and so we should take care with deterministic or definitive claims. 1/
I wouldn't suggest that this can turn around Russia's fortunes in the war. However, I would take care being overly dismissive, especially looking out towards the medium term of this winter and 2023. Force availability and manpower matters, hence the implications can vary. 2/

Brief thoughts on UA Kharkiv offensive. It appears ambitious, intended to envelop Izyum and try to trap Russian forces there. Likely seeking to interdict ground lines of communication at Kupyansk. The Oskil river east of Izyum makes the pocket vulnerable for RU forces. 1/
UA offensive looks to have made substantial gains, placing RU forces in a precarious position. From what one can tell, and these are early impressions, the advance made good use of armor in conjunction with infantry. 2/

Good thread by Jack. I've largely shied away from this conversation, because I often saw it falling victim to the false certainty of shaky numbers and estimates that seemed predicated on big assumptions.
My intuition has been that Russia probably had less usable ammunition to start than being given credit for, but also a lower daily use rate (15-20k vs the 50-60k figures which struck me as unrealistic), and production capacity which could be ramped up over time.
