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.

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.

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.

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.

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.
