The Pokrovs’ke - Hulyaipole front has seen the deepest Russian advances in the past month.
This thread will examine the 🇺🇦Ukrainian forces in the area, highlighting the many attached battalions that likely lead to degraded coordination between the units.

Overall command of this sector belongs to the 🇺🇦20th Army Corps, with the attached 102nd Territorial Defense (TDF) Brigade holding its right flank near Hulyaipole.

The 🇺🇦110th Mechanized Brigade seems to have a nearly 20 kilometer-wide area of responsibility, while the sector north of it sees the presence of several assault battalions under an unclear command. The 🇺🇦110th Mechanized Brigade is a clear example of a well-documented Ukrainian practice: battalions from other units are frequently attached to brigades struggling in defense. This often results in reduced coordination, cohesion and responsibility for the brigade commanders.

As mentioned in a post by the Brigade itself, the units attached to the 110th include:
- 3rd Battalion, 122nd TDF Brigade
- 4th Battalion, 105th TDF Brigade
- 3rd Mechanized Battalion, Presidential Brigade
- 1st Rifle Battalion, 125th Heavy Mechanized Brigade (possibly with elements of 2nd Mechanized Battalion)

🇺🇦 Two Ukrainian brigades have been transferred from the northern border areas to the eastern front.

The 144th and 154th Mechanized brigades redeployed in September to the Kup'yansk and Pokrovs'ke directions, respectively.

Both these sectors have recently seen Russian gains and likely needed reinforcements. The 🇺🇦144th Mechanized Brigade had been in Chernihiv region, on the northern border, since the spring.

By late September, it was transferred to the area near Kindrashivka.

It was specifically mentioned in President Zelenskiy's October 8th evening address, along with the 15th National Guard Brigade which the 144th is likely supporting.

🇷🇺 The Russian Naval Infantry grouping is now engaged in the Dobropillya area.
The 177th, 40th, and 155th Brigades are conducting attacks near Poltavka, while the 336th Brigade is operating near Nove Shakove.
For now, the 61st Naval Infantry Brigade appears to remain in reserve. Overall the marines are mixed in between 51st and 8th Army units.
Due to Ukrainian redeployments, the naval grouping now faces well-regarded units such as Rubizh NGU, Skala, 225th Regiment, 82nd and 95th Air Assault Brigades, 93rd Mech Brigade and more.

🇷🇺 Russian Regrouping
Due to water shortages in Donetsk, many Russian units turn to volunteers for essential supplies.
Through this we have been able to confirm that the 61st and 336th Naval Infantry Brigades are in Donetsk, joining the Russian Naval Infantry Grouping Russian Marines from the 61st Brigade, recently redeployed from Kherson, thank volunteers for donating water tanks in this video filmed at the 'Hypermarket' parking lot in Donetsk.

🇺🇦Ukrainian units are beginning to transfer out of Sumy, following Russia's regrouping that we reported on last week.

In this thread we will review the current Ukrainian disposition in Sumy, including recent changes and which units might move out soon.

During August, the 156th Mechanized Brigade transferred to the Pokrovsk direction (possibly around Shakhove and Sofiivka).

It was previously deployed in Yunakivka, where it was replaced by the veteran 47th Mechanized Brigade.

The 47th moved here from the border further west.

414th UAS Brigade "Magyar's Birds":
The biggest drone unit in the Ukrainian army, which recently announced the plan to double its size.
Mostly focused on strikes against soldiers and light vehicles, it benefits from changes in the point system (more points for killed soldiers).

🇷🇺Pokrovsk-Kostiantynivka ORBAT
The recent battles were shaped by three key aspects:
1. Forming of infiltration groups south of Pokrovsk in the 2nd CAA AO
2. Gradual redeployment of 51st CAA Units towards Rodyns'ke
3. Heavy fighting along Popiv Yar-Katerynivka line by the 8th CAA South-Pokrovsk:
Spetsnaz trained Infiltration groups along with 506th's "Typhoon" assault unit & the 35th MRB managed to move deep into the city attempting to destabilize the defense. The 15th MRB continues pressing the Udachne-Kotlyne line.

The Ukrainian 17th Army Corps (17AK) has likely deployed to the front, replacing the Operational Tactical Group (OTU) Zaporizhzhia.

Most units assigned to the Corps are currently holding the line between Kam'yans'ke and Huliajpole.

(Boundaries on the map are approximate) This is the composition of the 17th Army Corps, revealed on its socials in the past week and reported by @Militarylandnet.

It includes two TDF (Territorial Defence Forces) brigades: the 128th TDF Brigade was transferred to the Ground Forces in 2024 but is yet to be reorganized.

🇷🇺Summer Offensive
Today’s focus is the southern front, where Russian activity has surged over the past two months.
Currently, five Combined Arms Armies and one VDV Division are carrying out offensive operations as part of the 2025 summer campaign.
🧵 Central Zaporizhzhia saw advances toward Kam'yans'ke by two Air Assault Regiments from the 7th VDV Division, supported by infantry from multiple regiments of the 19th Division. Meanwhile, the 503rd Regiment was unsuccessful assaulting out of Nesterianka.

The Ukrainian 20th Army Corps (20AK) might be deploying to the frontline after revealing its units.

With 4 of its maneuver brigades currently operating in southern Donetsk, it will partly replace Tactical Group Vuhledar (TGr Vuhledar).

(Boundaries on the map are approximate) This is the composition of 20th Army Corps, as revealed yesterday in a post on its official Facebook page and initially reported by @Militarylandnet

🇷🇺 Russian units operating in Kursk/Sumy Oblast.
Thread:
Contrary to initial beliefs, most Russian units remained in Kursk and continued assault operations through April and May, with additional units recently reintroduced

The main efforts in the Bilovdy to Loknya area are carried out by the 76th Air Assault Division (104th, 234th and 237th Regiments) and 83rd Air Assault Brigade with 106th Airborne Division (51st, 119th and 137th Regiments) and 150th MRR supporting.

🇺🇦Ukrainian reinforcements west of Toretsk

Our previous thread on this area highlighted the lack of Ukrainian reinforcements (above battalion echelon) being committed.

It has since become clear that they actually arrived, beginning in late April.

https://x.com/WarUnitObserver/status/1921159945388535898

In the previous thread, we mentioned the deployment of the 501st Separate Marine Battalion of the 36th Marine Brigade from Kursk.

In reality, almost the entire 36th Brigade has been deployed to this sector, specifically between Novoolenivka and Kalynove.

We are discovering more and more of the structure of the new 68th Motorized Rifle Division, formed on basis of the 25th Motor Rifle Regiment

New formations:
121st Motorized Rifle Regiment: MUN 50183
122nd Motorized Rifle Regiment: MUN 50333
52nd Reconnaissance Battalion: MUN ?

https://twitter.com/WarUnitObserver/status/1916431133647970427

Previously under 25th Motor Rifle Brigade:
1009th Motorized Rifle Regiment: MUN 29298
Unlike the rest of the 68th Division, which is near Kupyansk, this Regiment is operating near Vovchansk

THREAD
Significant Russian troop movements in the Kupyansk direction.
Russia moves three regiments from Pishchane direction towards Terny, increases attacks near Kyslivka and reinforces the attack against Zapadne. The 1st Tank and 1st Motor Rifle Regiments of the 2nd Motor Rifle Division had been fighting on the south side of the Pishchane salient since at least 08.2024, this is their first major move in a long time. First MIAs near Terny started showing up in mid March 2025.

THREAD
In March Ukrainian forces attacked Belgorod oblast, capturing the villages of Demidovka and Popovka.
Apparently, more Ukrainian units than initially believed are involved, including several brigades previously in Kursk oblast and soldiers transferred from support branches. The main elements seem to be from 225th Assault Regiment, 47th Mechanized Brigade and 17th Heavy Mechanized Brigade
Interestingly, missing soldiers of 225th Regiment are in some cases transferred (or attached) from:
- 141st Brigade
- 201st AA Missile Brigade
- Unknown unit A4893

THREAD
Russian Nuclear Forces are used as assault infantry in the Toretsk direction.
In November 2024, trucks belonging to the 🇷🇺 12th Main Directorate crossed the border into Ukraine near 47.845276, 39.762979.
At that time we didn't know what their purpose was.
Now we do.
How did we identify the trucks? The double digit number on the right side of the license plates, "39", is exclusively used by the 12th Main Directorate (12 GU MO) and can be seen on every vehicle.

THREAD:
More Kurakhove transfers
After fighting in the Mariinka -> Kurakhove direction since the beginning of the war, Russia has started to transfer the 103rd Motor Rifle Regiment (MRR), MUN 91708, of the 150th Motor Rifle Division (MRD) towards Toretsk.

https://x.com/AudaxonX/status/1894105573819310402

This move isn't very surprising, after all the frontline in the area south and around Kurakhove has shrunken considerably in the last three months.
Shown below is a very simplified Order of Battle of the area. 20th Army, 68th Corps and 114th Motor Rifle Brigade will likely remain

1/19 The purpose of this thread is to inform on the variety of shapes of official Russian military patches/chevrons/heraldry and their meanings. Each post will have the shape of the patch and an example of a unit it belongs to. 2/19 This first shape signifies the branch of the Russian army. The example is for the Russian Strategic Rocket forces.

THREAD
Around the end of December 24, the remaining elements of the 810th Naval Infantry Brigade got moved from Pogrebki towards Kurilovka. Their positions at the northern Kursk frontline are now manned by the 34th Motor Rifle Brigade and the 22nd Motor Rifle Regiment.
The 810th Naval Infantry Brigade is the Russian unit that has suffered the most losses during the fighting in Kursk, which is also due to the fact that they were deployed there since the beginning.

THREAD
Ukraine is currently conducting a counterattack on the eastern Kursk frontline. Who are the Russian units opposing them? A report from Romanov suggests
11th VDV Brigade
104th air assault div!
204th Akhmat
78th Akhmat
GROM Cascade
177th naval infantry
810th Naval infantry We will provide evidence and context for all these units.
Notably missing from this list is the 40th Naval Infantry Brigade, whereas Sudoplatov posted a video of one of their drones striking a Ukrainian T-64BV thats claimed to also take part in the attack.
