ISW assessment for the 15th June. As of a couple minutes ago, one of the villages south of Velyka Novosilka mentioned in the article, Makarivka, has returned under Ukrainian control. https://twitter.com/War_Mapper/status/1668829293848215552
This comes after the joint statement by the US, UK, Netherlands, Denmark to supply Ukraine with air defence equipment. Germany dedicates Wisent-1 de-mining vehicles, Italy provides a “tranche of military aid for Ukraine, which includes weapon systems that are key for Ukraine’s defence” and Canada dedicates another $500mln USD to support Ukraine, including 200 anti-air missiles.
My guess is they are attempting to force Russia to commit their reserves to a location, pin them, and hit hard elsewhere.
