Why would Ukraine use cluster munitions to attack Russian positions?

Ukraine's military has made gains across the country, forcing Russian forces back from land previously occupied since Moscow's invasion.

Now, with established positions, could Ukrainian troops use cluster munitions to target Russian strongholds in the east of Ukraine?

Ukrainian forces have used the weapons during the conflict but what might be the tactical benefit of using them now?

• What is a 'dirty bomb' that Russia is accusing Ukraine of readying?
• IRIS-T: What is the German air defence system being used by Ukrainian forces?
• Ukraine war drone attacks 'waking up' world's militaries

Forces News spoke to Dr Gian Gentile, a retired Colonel and Operations expert at RAND Corporation, who said Ukraine are facing an "enemy force that seems to have gone onto some kind of operational defensive".

"If they are in dug-in positions and… you are able to find those positions through aerial observation of whatever type, then cluster munitions, I think, would be much more effective."
