Lots of recent discussion about the ‘slow’ Ukrainian offensives. What is actually occurring now is a steady, deliberate taking down of the Russian 'operational system'. This takes time. 1/25 🧵
2/ What is this operational system? To understand what it is, and how Ukraine is ‘taking down’ the Russian operational system, two foundational concepts are important to understand: the operational art; and, systems destruction warfare.
3/ In war, we talk about strategy (the link of purpose with high level resource allocation & action) & tactics (involving attacks & conduct of specific combat ops). Because of the complexity of modern war, strategy and tactics are linked through what we call Operational Art.
4/ Operational Art is the planning, orchestration, sustainment and adaptation of tactical actions over long period of time and, often, across a large geographic area as well. It ensures military forces are in a good position for tactical activity that achieves strategic outcomes.
5/ One element of the operational art that is debated is whether there is an operational ‘level’ of war. Critics argue that the operational level undermines strategy & relegates tactics to a less important aspect of war. Perhpas, but most nations recognise this level in doctrine.
6/ Systems Destruction Warfare. A RAND report notes that: “thinking about systems pervades virtually every aspect of the PLA’s approach to training, organizing, and equipping for warfare… the system-of-systems construct is the mode of modern fighting for the PLA."
7/ PLA theorists view modern war as a confrontation between opposing systems in a multidomain battlespace. As such, the Chinese seek to build their own systems to attack enemy systems. An important component of this is degrading and destroying the enemy ‘operational system’.
8/ An operational system is the components of a military force – above units and brigades – that binds a force together, allows for concurrent and sequential tactical activities, and underpin its ability to conduct operational level maneuver that achieve strategic objectives.
9/ For the Russians in #Ukraine, there are 6 key elements of their operational system: the command system, the firepower-strike system, the information system, the reconnaissance-intelligence system, the support system (logistics etc); and, the learning and adaptation system.
10/ In essence, this is the brain and nervous system of the Russian forces in Ukraine. This operational system will have been a first-order target when planning and executing military campaigns.
11/ The reason for this is that if the Ukrainians can attack the Russian brain (such as it is) and nervous system, the limbs are unable to be coordinated, and can be isolated and destroyed.
12/ Therefore, when the Ukrainians have asked for modern fighters, long range strike (and probably classified cyber and IW capabilities as well), they have been requesting the capabilities to attack, degrade and destroy the Russian operational system.
13/ All six elements of the Russian operational system have been attacked in the lead up to the Ukrainian offensive beginning in June, and they continue to be attacked. The cumulative effect of Ukrainian attacks on the Russian system will be aggregated & measured regularly.
14/ There will be a time when Ukraine assesses the Russian operational system has been sufficiently degraded, its ability to support tactical forces damaged & the ability to move reserves has been limited. This decision point will inform when large-scale ground combat begins.
15/ Unfortunately, in the west, the only model we have for taking down an enemy operational system is the US in the 1991 Gulf War. A 42-day campaign using thousands of aircraft was needed. We then have to look back further into history to see a campaign of this complexity.
16/ So, in short, there is no modern comparator for what Ukraine is trying to do. It lacks control of the air, and western nations have failed to provide the kinds of modern fighters, or the quantity of long range attack systems (eg. ATACMS), needed.
17/ Therefore, Ukraine has had to think & plan creatively for a different way to take down the Russian operational system. This has involved HUMINT in rear areas, use of civil and military intelligence collection, and selective tactical actions to prompt Russian responses.
18/ Russian responses aren't just tactical. Ukraine will be hoping to also see how Russian operational level C2 makes decisions & how its communication networks work. They will also want to find key reserve units, assess triggers for their deployment, and how long it takes.
19/ Other objectives of this current phase of degrading the Russian system including finding & destroying logistics / engineers (who lay minefields) as well as fire support units. Given the size of the Russian force in Ukraine, this is a considerable undertaking & takes time.
20/ While this is occurring, information & lessons are being fed back into the Ukrainian system to improve targeting and their knowledge of the Russian operational system. And, it provides time for Ukrainian units to be raised, trained and rehearsed for their roles in later ops.
21/ That time will come. But before then, #Ukraine will do everything it can to make these ground combat operations as uneven as possible in their favour. That means they must steadily, methodically take down the Russian operational system over the coming weeks.
22/ One final element of this approach is important. In holding back most of their tactical forces, the Ukrainians have a lot of flexibility about where they eventually make their main effort in subsequent phases.
23/ This Russian system, perhaps the most complex multi-domain system ever constructed, includes EW, air defence, long range fires, multiple protected N2 nodes, etc. No country on earth, besides the US, could attack and degrade such a system. Except #Ukraine.
24/ When they do, the Ukrainians will have disconnected tactical units from achieving Russia’s strategic objectives in Ukraine. They will have given their soldiers the best chance of breaking through the Russia defensive lines & unhinging their operational scheme of defence. End
25/ For those who are interested, I will be publishing a longer piece at my substack that explores this topic. . Thank you to the following whose images were used in this thread: @Militarylandnet @combined2forcesmickryan.substack.com

America has just released its 2026 National Defense Strategy (NDS). Not seeing much press activity from the Dept of Defense/War on this. While I need time to ponder the deeper implications of the document, a few things stand out on first reading. 1/11 🧵 Image
2/ First, the document is consistent with the 2025 National Security Strategy (NSS) released by the Trump Administration in November 2025. Key priorities in the NDS align with the NSS, as you would expect. However, while the NSS has priorities, the NDS has "Lines of Effort".
whitehouse.gov/wp-content/upl…
3/ There are four Lines of Effort in the new NDS:

1. Defend the U.S. Homeland.
2. Deter China in the Indo-Pacific Through Strength, Not Confrontation.
3. Increase Burden-Sharing with U.S. Allies and Partners.
4. Supercharge the U.S. Defense Industrial Base.

"The Oreshnik is the sign of a Fearful, Worried Putin, Not a Leader Confident of Victory." My first 2026 update on war and great power competition. This week: the Oreshnik attack, peace talks progress, the ground war in #Ukraine, China's reaction to Venezuela and more. 1/5 🧵🇺🇦 (Image: @DefenceU)Image
2/ In events related to #Ukraine this week, the Oreshnik strike absorbed a lot of attention. But this was not an event that demonstrates Russia's strength. Indeed it showed the opposite. Also, peace talks in Paris took place as did a meeting of the Coalition of the Willing. Image
3/ In the Pacific, China continues to posture about American operations in Venezuela. While we might like to think that China will practice what it preaches with regards to its statement that “military means are not the solution to problems”, its accelerating use of military coercion and aggression against neighbours shows just how hollow and hypocritical the Xi regime is.

Also this week, Trump discussed Taiwan in his New York Times interview.Image

On 29 December, just as the summit between Zelenskyy and Trump was finishing at Mar-a-lago, the PLA Eastern Theatre Command announced that it had commenced exercise "Justice Mission 2025" in the #Taiwan Strait. I have just published an assessment of what China designed it to achieve, and how we can learn from it. 1/8 🧵🇹🇼Image
2/ Exercise Justice Mission 2025 has taken place at multiple locations around Taiwan. While the maps demonstrate the physical environment of the exercise, the more important exercise “location” is the minds of Taiwanese and foreign observers. But perhaps the most important exercise location is the mind of the U.S. president. (Map: @TaiwanMonitor)Image
3/ The exercise will have been designed by the Chinese with multiple objectives beyond the normal political coercion of Taiwan. These objectives include:
-rehearsing military activities for different Taiwan contingencies, including decapitation operations.
-continue developing the skills of the commanders, staff, units and overall command and control of the Eastern Theatre Command.
-assess the response of Taiwanese and American political and military systems.
-normalise large joint operations around Taiwan.

Putin can play Trump like a fiddle. But the bigger issue is that Putin has clearly decided that continuing the war in #Ukraine - while keeping Trump on side - is more advantageous to him (for now) than agreeing to any peace deal. This is a deliberate Russian provocation to get Ukraine-haters worked up and undermine the peace process. 1/6 🧵
2/ Putin has wasted no time in making his views on the current 20-point plan clear. He does not like it, but needs to keep Trump from placing more sanctions on Russia. If the current peace plan isn’t dead, it may be on life support. Will Trump hold Putin to account for this however?
3/ And today, Putin held a carefully scripted ‘military update’ with senior military commanders to further shape the minds of decision makers Washington DC, Beijing and elsewhere around Russia’s inevitable victory. The key theme - everything is going well, the enemy (Ukraine) is doing badly and we must continue fighting to ‘liberate the Donbas and Zaporizhzhia.

The much-anticipated summit between the leaders of #Ukraine and America, held at President Trump’s #Mar-a-Largo resort, has just concluded with a press conference. A quick update on outcomes. 1/15 🧵🇺🇦 Image
2/ This is the latest meeting between Trump and Zelenskyy since Trump returned to the White House in early 2025. Some of the meetings did not go well, such as the now-infamous 28 February Oval Office meeting. Others just kicked the can down the road, such as the Alaska Summit.
3/ In the lead up to the meeting, Ukraine released details of a 20-point peace plan that would be discussed with the Trump administration, and then potential presented to the Russians. The draft plan covered multiple subjects, including security guarantees for Ukraine, Ukrainian membership of the EU, reconstruction and territory.

Also, Trump had a 2.5 hour phone conversation with Putin - a call that was as long as today's main meeting between Ukraine and the US.

I recently returned from another research visit to #Ukraine, my second for 2025. I have written a new white paper, published by the @CSIS, which explores 7 strategic insights based on knowledge gained on my recent visit & other research. 1/7 🧵🇺🇦 Image
2/ The white paper covers a range of subjects related to how #Ukraine and #Russia are fighting this war. The seven insights not only illuminate the state of the war, and the degree of learning and #adaptation occurring, they provide lessons that western military institutions must analyse and heed.
3/ The seven subjects covered are:

1. Drone saturation and Russian drone innovation.
2. The new tactical battle triangle.
3. The ongoing and accelerating adaptation battle.
4. Long-range strike operations.
5. Ground-based air defence.
6. Russia's tactical and strategic advantages.
7. War strategy and trajectory.

I highlight just a couple of these below.
