Russian troops are increasing the pace of their offensive in different directions, - ISW maps

Operation No. 1 - Luhansk region

On 4 April, positional fighting continued on the Kupyansk-Svatovo-Kreminna line, but there were no confirmed changes in the front line in this area.

Positional fighting continued :

• west of Svatove in the area of Andriivka;
• west of Kreminna in the area of Yampolivka and Terny;
• south of Kreminna near Bilohorivka.

The Russian source said that the highly developed capabilities of Ukrainian aerial reconnaissance complicate Russian offensive operations in the Lyman direction.

Operation No. 2 - Donetsk region

On April 4, Russian troops carried out a heavily reinforced mechanized assault in the direction of Chasiv Yar (west of Bakhmut) and advanced to the eastern outskirts of the village.

Geolocation videos published on 4 April show Russian troops conducting an intensified mechanised attack on Chasiv Yar. The Russian mechanised column advanced along the T-0506 (Khromove-Chasiv Yar) road to the eastern edge of the Kanal neighbourhood (the easternmost part of Chasiv Yar) before Ukrainian forces prevented the Russian forces from advancing further into Chasiv Yar.

Russian forces are now increasing the pace and scale of their mechanised offensives across eastern Ukraine and may be increasing the overall pace of their offensive operations in Ukraine.

According to ISW, the Russian military is currently prioritising offensive operations on the Avdiivka, Bakhmut and Lyman directions.

Russian troops have recently advanced elsewhere northeast and west of Bakhmut amid trench fighting in the area.

The geolocation video shows that Russian forces have recently advanced north of Vesele (north-east of Bakhmut). Russian forces also recently advanced northwest of Berestove (northeast of Bakhmut) and captured a large part of the southern part of Ivanivske (west of Bakhmut).

Positional fighting continued:

• north-east of Bakhmut in the area of Verkhnekamianske, Vyymky, Spirne;
• north-west of Bakhmut in the area of Bohdanivka;
• west of Bakhmut in the area of Ivanove and Stupochky;
• south-west of Bakhmut in the area of Klishchiyivka and Andriivka.

On April 4, positional battles continued west of Avdiivka.

Russian military bloggers claimed that Russian troops had advanced to a depth of 830 metres southeast of Umanske (west of Avdiivka) and to a depth of 600 metres in the area of Semenivka (west of Avdiivka). On 3 and 4 April, Ukrainian forces also conducted several counterattacks in the area of Tonenke (west of Avdiivka), Umanske, Vodyane (west of Avdiivka) and Pervomaiske.

Positional fighting took place:

• west of Avdiivka in the area of Yasnobrodivka;
• south-west of Avdiivka in the area of Nevelske.

A representative of the Ukrainian brigade operating in the Avdiivka sector stated that Russian forces are trying to advance in the area as long as weather conditions allow, likely referring to ground conditions that will become less favourable for mechanised manoeuvres and muddier with the onset of spring.

Russian troops recently advanced west of Donetsk amid ongoing trench fighting west and southwest of Donetsk on April 4. Geolocation video released on April 1 shows that Russian troops have recently advanced southeast of Krasnohorivka (west of Donetsk).

Positional fighting continued:

• west of Donetsk in the area of Krasnohorivka and Heorhiivka;
• south-west of Donetsk in the area of Pobeda, Novomykhailivka, Kostyantynivka and Vodiane.

A Ukrainian officer said that Russian forces continued to attack in small infantry groups west and southwest of Donetsk.

On 4 April, positional fighting continued in the Donetsk-Zaporizhzhia border area south of Velyka Novosilka in the vicinity of Staromayorske and Urozhayne.

"Southern Axis"

On April 4, positional battles continued in the west of the Zaporizhzhya region, but there were no confirmed changes on the front line.

Positional battles continued in the Robotyno area and northwest of Verbove.

Also, positional battles continued on the left bank of the Kherson region, probably in the Krynky area, where Ukrainian troops maintain positions.
