It is 16 days since the Russian invasion of Ukraine began. Today I will examine the the importance of the adaptation battle in war, and how it is playing out in Ukraine. (Image - BBC) Image
2/24 As always, a shout out to those reporting on the Russian invasion. This includes @KofmanMichael @maxseddon @IAPonomarenko @RALee85 @shashj @DanLamothe @ikhurshudyan @IanPannell @DefenceHQ @TheStudyofWar @siobhan_ogrady
among others. Please follow them.
3/24 It is impossible for the military to anticipate every eventuality in war. There are too many scenarios to accurately predict wartime events. As such, a key virtue for military organizations in war must be adaptability to unexpected events.
4/24 In his famous essay, The Use and Abuse of Military History, Sir Michael Howard described the problem thus: “It is not surprising that there has often been a high proportion of failures among senior commanders at the beginning of any war.”
5/24 “These unfortunate men may either take too long to adjust themselves to reality…of they may have had their minds so far shaped by a lifetime of pure administration that they have ceased…to be soldiers.” Read it all here: press.armywarcollege.edu/cgi/viewconten…
6/24 As Williamson Murray writes, because war “is interactive, both sides have the potential to adapt to the conflict at every level…thus the problems posed by the battlespace do not remain constant. More often than not they change with startling rapidity.” Image
7/24 The exploration of adaptation has resulted in the development of a range of concepts on how adaptation occurs & how it can be applied. In military literature, the best-known adaptive cycle is Boyd’s OODA (observe-orient-decide-act) loop. Image
8/24 Frank Hoffman has also proposed a model for military adaptation which he calls Organisational Learning Capacity. It has four parts: leadership; organisational culture; learning mechanisms; and, dissemination mechanisms.
9/24 So, effective military institutions need to adapt in war, at every level, and share lessons broadly to ensure an entire force can learn from both success and failure. Military institutions must win the adaptation battle at the strategic, operational & tactical levels.
10/24 What kind of adaptations have we witnessed in this war so far?
11/24 From the Russians, they had to adapt their campaign within the first 48 hours because their attempt at a lightening conquest of Ukraine failed. This was most obvious in the north and the attempts to capture Kyiv. They had to adapt their campaign to what we are now seeing.
12/24 Further, they have experienced major challenges in the ability to coordinate combined arms warfare on the ground - it has seen them advance much slower, and sustain more casualties, than anticipated. They have therefore adapted to rely more on firepower than maneuver.
13/24 For the Ukrainians, they have clearly recognised that the Russians have poor rear area security. They have adapted their operations to fight the Russians in the rear areas. It is hard for the Russians to advance when they have to constantly look over their shoulders.
14/24 The Ukrainians also appear to have adapted based on the big inflow of western crew served anti-tank and anti-aircraft weapons. This isn’t to say they did not have them previously. But it appears these now have greater emphasis in Ukrainian operations.
15/24 Finally, the Ukrainians have adapted in the info environment. Not only did they seize the initiative at the start of the war, they have learned and evolved in a tactical, operational and strategic influence fight against Russian misinformation. (Image - @IAPonomarenko) Image
16/24 There will be many other adaptations on the ground we are not seeing. In due course, we will need to study other military adaptations – from both sides – that will emerge.
17/24 Finally, what military adaptations might we see in the near future in Ukraine?
18/24 The Russians are clearly still attempting to improve their ability to plan and coordinate large scale ground maneuver. We may see them adapt their communications to be more secure, improve logistics, and replace incompetent commanders to improve tactical performance.
19/24 We may see increased Russian operations in the west as they adapt their overall campaign. They will need to halt, or severely restrict the flow of western arms and other aid, into Ukraine. This will force Ukraine to adapt is defensive campaign.
20/24 From the Ukrainians, we may see an #adaptation to their overall scheme of defence where they start focussing more on support to insurgent forces in areas already captured by the Russians. At the same time they will need to sustain conventional operations.
21/24 The Ukrainians are also adapting their tactical force structure to absorb foreign combatants and support personnel. Given training, language and cultural differences, this will be a significant adaptation for them to manage.
22/24 As I note in #WarTransformed, military organizations are never at a steady state. The rapid pace of change means that they will be adapting at each level concurrently and doing so constantly. This adaptation battle is what we are seeing play out now in Ukraine.
23/24 There are other good references on this topic. Here are just three of my favourites – among many – on the topic of military adaptation. Image
24/24 Adaptation is a central component of war, and a 'learning culture' is key to institutional adaptation. There will be more adaptations to observe in Ukraine in the days & weeks ahead. I will take a break tomorrow, and return with my daily thread on Monday. End.

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.

Yesterday, my report on the new global adaptation war was published by the @scsp_ai . The report proposes that the learning and adaptation ecosystem spawned by the war in #Ukraine has now metastasised into an international learning and #adaptation competition. 1/10 🧵🇺🇦 Image
2/ As the report describes, in the past three years, Ukraine and Russia have learned and adapted. Both sides have also learned to learn better and to absorb lessons into their military and industrial systems with increasing speed. But the sharing of lessons by both nations has seen the Ukraine Adaptation Battle transform into a global Adaptation War.
3/ A new adversary learning and adaptation bloc has emerged. While not a formal alliance, China, Russia, Iran and North Korea have developed a mesh of different agreements and strategic partnerships that have allowed these authoritarian regimes to construct a connected knowledge market on 21st century strategic competition and conflict.

I have just published my weekly update on modern war and strategic competition. This week: the Battle of Pokrovsk, Russian casualties, deep-strike campaigns, China's 3rd aircraft carrier commissions, as well as my recommended war and national security reads. 1/5 🧵🇺🇦 Image
2/ In #Ukraine, the Battle of #Pokrovsk continues. While an audacious air assault was conducted this week, it is hard to see that it will arrest the overall Russian momentum in enveloping the city. Both Ukraine & Russia are continuing their deep strike operations in the lead up to winter, although Ukraine's strikes are yet to change Putin's strategic calculus about the war.
3/ In the #Pacific, Chinese aggression around #Taiwan continued, albeit at a lower tempo than previous months. The Chinese also commissioned their third aircraft carrier during the week. Taiwan announced several initiatives related to the operation of unmanned systems.
