What are some strategic questions from the article about Russian-Ukraine war?
Article: BAKHMUT – Mr Yevgeny NAME_1, leader of Russian mercenary force NAME_2 Group, said in a sudden and dramatic announcement on Friday that his forces would pull out of the Ukrainian city of Bakhmut, which they have been trying in vain to capture since last summer.

NAME_3 said they would withdraw next Wednesday – ending their involvement in the longest and bloodiest battle of the war – because of heavy losses and inadequate ammunition supplies. He asked defence chiefs to insert regular army troops in their place.

“I declare on behalf of the NAME_2 fighters, on behalf of the NAME_2 command, that on May 10, 2023, we are obliged to transfer positions in the settlement of Bakhmut to units of the Defence Ministry and withdraw the remains of NAME_2 to logistics camps to lick our wounds,” he said in a statement.

“I’m pulling NAME_2 units out of Bakhmut because in the absence of ammunition, they’re doomed to perish senselessly.”

Bakhmut, a city of 70,000 people before the start of the war, has taken on huge symbolic importance for both sides because of the sheer intensity and duration of the fighting there.

NAME_2 has been spearheading Russia’s attempt to capture it and NAME_3 said three weeks ago that his men controlled more than 80 per cent of the city. But Ukrainian defenders have held out, and NAME_3 has vented increasing anger at what he describes as lack of support from the Russian defence establishment.
