Although Russia's main center of attack remains the Severodonetsk-Lysichansk direction, a week of intense shelling indicates Russian attempts to restore the pace of offensive on the northern axis from Izyum, British intelligence says.

Analysts note that Ukrainian troops continue to hold the line in this sector, making good use of the forest area to support their defenses..

“In the coming weeks, the Russian campaign is likely to increasingly rely on the echelons of reserve forces.. They consist of several separate components, which Russia has almost certainly begun to use, ”the intelligence officers say..

Intelligence notes that in the Russian army combat reserve is a recent innovation, consisting of part-time volunteer reservists and, as a rule, intended for security tasks in the rear..

Also, the Russian authorities are using volunteers from veterans who have served in the regular army over the past five years to replenish the third reserve battalions as part of regular brigades..
