🇷🇺 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 Image
Image
Image
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. Image
The recently redeployed and reintroduced 155th Naval Infantry Brigade, 30th MRR and a 200th MRB battalion operates in the Kostyantynivka - Volodymyrivka area Image
In the Gornal’-Guevo area, the 810th Naval Infantry Brigade, supported by the 22nd and 1427th MRR, continued to take substantial casualties throughout May.
Meanwhile, the Strategic Missile Forces regiment and the 177th Marine Brigade continued their attacks south of Plekhovo. Image
Another area of interest is Tetkino, where the 56th and 217th Air Assault Regiments are defending alongside the 2nd Spetsnaz Brigade. Infantry reinforcements are being provided by the 1st VKS Regiment and reserves from the 346th training ground Motor Rifle Regiment. Image

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.Image
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)Image
Image
The 🇺🇦102nd TDF Brigade to the south has also received reinforcements, with 🇷🇺Russian forces attacking Poltavka since early October.

Specifically, a Battalion Tactical Group based on the 2nd Mechanized Battalion of the 🇺🇦142nd Mechanized Brigade was deployed here and experienced critical issues in its command, leading to the loss of the settlement.
Unconfirmed rumors mention the commander was often under the influence of alcohol.

The 🇺🇦74th Recon Battalion, which had previously operated in this area, was brought in to remedy the situation.Image

🇺🇦 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.Image
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.Image
The 🇺🇦154th Mechanized Brigade had mostly been on the border between the Kharkiv and Belgorod oblasts in early 2025, although some elements had been seen north of Kup'yansk.

By late August it began deploying near Novomykolaivka (Dnipro oblast), where Russian forces have, however, continued advancing.Image

🇷🇺 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. Image
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. Image
Sources, 155th Marines:
Several very recent MIA, mentioning Poltavka

🇷🇺 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 Image
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.
Image
Image
The 336th Naval Infantry Brigade has redeployed toward Pokrovsk as well, joining the 177th Regiment and the 61st, 155th and 40th Brigades already in the area — all likely operating under the Russian Naval Infantry grouping. Image

🇺🇦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.

Image
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. Image
Units in the rest of the salient do not seem to be in the process of moving at the moment.

It is worth highlighting that the 225th Assault Regiment may have reduced its presence around Andriivka to a single battalion (Shkval Battalion) following counterattacks in early summer. Image
