🇺🇦 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 🇺🇦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.

Unfortunately, it seems 🇷🇺Russian pressure was heavy in the initial stage of this deployment: a relatively high amount of MIA/KIA reports from the 🇺🇦154th Brigade was recorded during September (more than ten).

Whether this is due to higher command issues or problems within the brigade can not be determined from open sources.

The deployment of two 🇺🇦brigades from relatively inactive sectors once again proves that the Ukrainian Defence Forces maintain a certain amount of units in reserve.
