It seems like Russia is Valuyki, Belgorod as base for this operation, there haven't been any geolocated strikes in the city in the last few months which also indicates a low priority by Ukraine.

The area had been mostly quiet before the capture of Milove by the 🇷🇺 83rd Motorized Rifle Regiment in early July. Since then Russia has been trying to advance towards Ambarne in the south and most recently the 7th and 79th Regiments captured Odradne further to the south.

Unit Observer @warunitobserver.bsky.social · 14/10/2025

🇷🇺 Russia has moved four Regiments and elements of two more from northern to western Kharkiv since the beginning of July. This marks another shift away from the northern direction. This transfer aims at reinforcing the successes near Kupyansk, whereas the Russian northern campaign has mostly failed.

🇷🇺 Russia continues to redeploy forces away from southern Pokrovsk -90th Tank Division is now entirely south of Ivanivka-Novopavlivka -35th, 55th, 74th, 137th Brigades redeployed from southern Pokrovsk towards Novopavlivka -Only 15th, 30th Brigades & elements of 27th Division remain south of Pokrovsk

1376

Unit Observer @warunitobserver.bsky.social · 24/09/2025

So far we have found evidence for 3 Regiments of the 90th Tank Division moving to the south of the Vovcha River. We expect the other two Regiments (239th and 428th) to arrive soon as well. Their likely goal is to expand to the west towards the river and cross it in the north towards Novopavlivka.

Unit Observer @warunitobserver.bsky.social · 24/09/2025

Russia has steadily expanded its control west of Velyka Novosilka over the last months. The Eastern Grouping tries to circumvent a deadlock at the Vovcha River by moving multiple Brigades towards the south. Namely the 5th Tank, 36th and 37th Motorized Rifle.

🇷🇺 Unit movements in the south Donetsk direction: - 29th and 36th Army shifted south to reinforce the push towards Pokrovs'ke - 90th Tank Division took up the positions near the Vovcha river - 74th and 137th Brigade take over old 90th Tank Division positions

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. vk.com/wall31029257...

🇷🇺 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 redeployments continue. The battered 11th Air Assault Brigade has moved from Sumy to Kherson to free up the 104th Air Assault Division for further offensive operations in southern Zaporizhia

1276

Unit Observer @warunitobserver.bsky.social · 06/09/2025

Important units in Sumy have been the 80th and 95th Air Assault brigades, pictured here in the sectors they have held during the summer (near Yunakivka and east of it). These highly capable units are likely to be earmarked for transfer to the east, should the necessity arise.

070

Unit Observer @warunitobserver.bsky.social · 06/09/2025

From west to east, the current disposition includes 71st Jager Brigade, 15th "Stalevyi Kordon" Border Detachment and 1st Heavy Mechanized Brigade. The 103rd TDF, 17th Heavy Mechanized and 21st Mechanized brigades hold, respectively, the borders west and east of the salient.

190

Unit Observer @warunitobserver.bsky.social · 06/09/2025

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.

130

Unit Observer @warunitobserver.bsky.social · 06/09/2025

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.

Unit Observer @warunitobserver.bsky.social · 06/09/2025

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.

The most critical part of 3AK's sector is the area held by the 60th and 66th Brigades - the northern Lyman axis. These brigades have had limited rotations in the past year, so it remains to be seen whether 3AK can stabilize the situation and slow down the recent Russian advances.

1120

Unit Observer @warunitobserver.bsky.social · 11/08/2025

Notably, it seems the 21st Unmanned Systems Regiment was partly formed on the basis of the 21st Special Purpose Battalion of the Presidential Brigade. The 3rd Assault Brigade's own Unmanned Systems Battalion also provided personnel and experience.

160

Unit Observer @warunitobserver.bsky.social · 11/08/2025

The 115th Mechanized Brigade provides support and attached elements between Lyman and Kupyans'k. For the moment, it does not seem like it will join 3AK.

140

Unit Observer @warunitobserver.bsky.social · 11/08/2025

The 66th Mechanized Brigade is not organically part of the 3AK for the moment: in a recent post it was mentioned as "attached". It is unclear whether this will remain the case, as it holds a crucial sector in the center of the 3AK's area of responsibility.

140

Unit Observer @warunitobserver.bsky.social · 11/08/2025

The four Brigades announced so far hold sectors between Stepy and the Serebryans'kyi Forest - this is claimed to be the largest Ukrainian Corps sector so far, spanning up to 150 kilometers of frontline.

140

Unit Observer @warunitobserver.bsky.social · 11/08/2025

This is the composition of the 3rd Army Corps. The maneuver brigades were revealed on the Corps' socials last week, while other varied sources confirmed the existence of many support units.

Unit Observer @warunitobserver.bsky.social · 11/08/2025

The Ukrainian 3rd Army Corps (3AK), based on the infamous 3rd Assault Brigade, revealed part of its subordinate Brigades last week. Their sector is the Izyum axis and, as was previously reported by Ukrainian press, they replaced Tactical Group "Kreminna" in June.

If you'd like to know more about the 17th Army Corps, here is our recent overview post: bsky.app/profile/waru...

Unit Observer @warunitobserver.bsky.social · 18/07/2025

The 241st TDF Brigade seems to have battalions spread around the frontline, but its UAS units have recently become active in Kam'yans'ke. The 44th Artillery Brigade has had elements on the southern front since 2023, along with detachments in the Sumy direction.

141

Unit Observer @warunitobserver.bsky.social · 18/07/2025

The 110th Mechanized Brigade is not currently deployed: following fighting in Velyka Novosilka, it rotated out in April but suffered a deadly strike on its command post in the rear (Huliajpole, Dnipro oblast) on July 1st. Elements remain in the Sumy and Novopavlivka directions.

120

Unit Observer @warunitobserver.bsky.social · 18/07/2025

Marfopil, Malynivka and Olhivske fall under the 102nd and 110th TDF Brigades - these are not currently part of 17th Army Corps. However, they likely were under OTU Zaporizhzhia in the past, so it is unclear whether they will be attached to 17AK or remain separate.

120

Unit Observer @warunitobserver.bsky.social · 18/07/2025

The 3rd Battalion "Volyn" of the UDA (Ukrainian Volunteer Army) was deployed near Myrne in the spring. The 108th TDF Brigade has been holding the front west of Hulyaipole since 2023.

120

Unit Observer @warunitobserver.bsky.social · 18/07/2025

Moving East, the 65th Mechanized Brigade's sector has remained the same since late 2022. The Free Russia Legion has been operating in this area in the early summer. Mala Tokmachka, north-east of the infamous Robotyne, has been under the 118th Mechanized Brigade since late 2023.

120

Unit Observer @warunitobserver.bsky.social · 18/07/2025

On the western flank, the frontline towns of Kam'yans'ke, Stepove and Mali Shcherbaky have long been held by the 128th TDF Brigade and 128th Mountain Assault Brigade respectively. Check out our in-depth look on this area, posted earlier this week: bsky.app/profile/waru...

Unit Observer @warunitobserver.bsky.social · 18/07/2025

This is the composition of the 17th Army Corps, revealed on its socials in the past week and reported by @militaryland.net. 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.

120

Unit Observer @warunitobserver.bsky.social · 18/07/2025

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)

1131

Unit Observer @warunitobserver.bsky.social · 14/07/2025

In the past few weeks, the new 17th Army Corps has taken charge of this sector of the front and a large area to the East. We will cover the larger picture in a thread in the coming days.

Unit Observer @warunitobserver.bsky.social · 14/07/2025

During the spring, this area saw the deployment of other separate units such as HUR's special unit "Artan" and "Kastus Kalinouski" Regiment. Various drone units, including the 412th, 422nd, 423rd and "Flying Skull" Unmanned Systems Battalions also previously operated here.

150

Unit Observer @warunitobserver.bsky.social · 14/07/2025

The 131st Recon Battalion and HUR's special unit "Kraken" have been operating in Kam'yans'ke itself, along with (recently) the National Guard "Omega Wings" unit. 241st TDF Brigade's drone company "Vyrii" has also appeared here, but the TDF battalions still seem to be elsewhere.

100

Unit Observer @warunitobserver.bsky.social · 14/07/2025

What Ukrainian units are defending Kam'yans'ke against the recent Russian push? The overall sector belongs to the 128th Territorial Defence (TDF) Brigade, supported by various attachments. The 128th Mountain Assault Brigade holds its eastern flank. Yes, this can be confusing.
