• After a long hiatus, Wagner Group mercenaries are back on the battlefield, Ukraine's military says.
• Around 500 fighters from Belarus will help Russian combat operations around Bakhmut.
• Officials and experts say they're not likely to have much battlefield impact without Yevgeny Prigozhin.

Wagner Group mercenaries are back in Ukraine after a lengthy absence from the battlefield. These fighters appear to be some of the best within the Russian ranks, but the threat is still low without their leader, Kyiv's military says.
