Further Details Emerge on 3rd Army Corps
The newly established 3rd Army Corps, formed on the basis of the legendary and battle-hardened 3rd Assault Brigade, has officially been announced across its social media platforms after much anticipation.
MilitaryLand recently uncovered the first information regarding the corps, including the confirmation that the 60th Mechanized Brigade had joined, alongside many other support units that were forming or being elevated to the corps level. This information was revealed from a foreign recruiter of the 3rd Assault Brigade, which was eventually taken down on the UkraineForeignLegion subreddit, where it was originally shared.
Influence of the Corps
Today, on August 4, 2025, the 3rd Assault Brigade reorganized and rebranded its social media channels into the 3rd Army Corps. An announcement was also published by the corps commander, Andriy Biletskiy, who confirmed that the unit had been formed in the spring of 2025, which was March, when it was first formally announced, and also spoke about the mission the corps is undertaking on the front
“Our bridgehead is the last line of defense for Northern Donbas and Kharkiv region. The corps holds about 150 km – approximately 12% or 1/8 of the entire front line. It can be confidently stated that the Third Corps is already influencing the course of this war,” said Biletskyi.
The decision to rebrand and reorganize its channels echoes the similarity with the Azov Brigade and the 1st Azov Corps rebranding, with the brigade’s socials being rebranded due to the significant influence and following it already has.
New assignments to the Corps
As previously mentioned, the 60th Mechanized Brigade joined the corps in July 2025, being disclosed by recruiters affiliated with the 3rd Assault Brigade. As of August 4, 2025, it has now been confirmed that two more brigades have joined the formation. The first being the 53rd Mechanized Brigade, which currently held positions in the Serebryansky forest.
The 63rd Mechanized Brigade has also been placed under the command of the corps and has been working extensively in the Luhansk direction alongside the 60th Brigade for some time. This was indicated through the brigade’s social media channels, reposting the announcement of the corps, signalling formal affiliation.
As with the other corps assignments, it is expected that it will include a heavy mechanized brigade and a dedicated artillery brigade. At present, however, no specific units have been confirmed to be assigned to the corps. Some recently restructured Territorial Defense Brigades, being reformed into heavy mechanized structures, remain possible candidates.
It was also recently confirmed that the 122nd Communications Battalion is a part of the corps and has received its own unique insignia and military unit number.

Azov, wolf’s angel logo and an obsession with being the 3rd. It is slightly owed to your audience to mention the controversy with this group since you have called them legendary instead of infamous and their blatant use of flags such as the wolf’s angel and black sun and what they represent and who flies those flags.
Interesting. I knew the 3rd Army corps was responsible for the front from Lyman to Borova. However, if their front line really stretches 150km, does that mean it also extends up to Kupiansk and even further north toward the Russian border? That’s news to me.
If I recall correctly, the 10th Army Corps will be holding the Kupyansk area, meaning that this will be their responsibility, and that the 3rd Army Corps will likely stop around the Serebryansky Forest with the 53rd Mechanised Brigade.
Ah ok – Biletsky was mentioning 150 km so I was trying to figure out where It started and where it ended.
