Ukraine announced the expansion of its Marine Corps on March 1, 2026, converting all coastal defense brigades into marine brigades, as reported by Militaryland.net and shared by the Ukrainian Propaganda channel on X at approximately 2:00 PM UTC during the 59-minute reporting window from 1:46:35 PM to 2:46:17 PM UTC. The reform aims to strengthen naval infantry capabilities amid ongoing conflict with Russia. Militaryland.net detailed the restructuring in a post referenced by the Ukrainian Propaganda channel, linking to full details on brigade transformations. This development follows earlier reports from Andrew Perpetua on March 1 at 1:46 PM UTC of 5,406 Russian soldier deaths in February 2026, the highest monthly total recorded by his group based on video evidence. Separate posts from the same channel during the window criticized Russian drone penetrations of allied air defenses, stating one Shahed drone breaks through defenses, and quoted Kremlin spokesman Dmitry Peskov claiming Russia must remain an island of wisdom amid global chaos. Anton Gerashchenko shared on X a statement attributed to Vladimir Putin expressing condolences for the death of Iran's Ayatollah Khamenei, calling it a cynical murder violating international norms. A Telegram account believed to belong to Alexander Dugin expressed concern that Russia could be next if Iran collapses, as relayed in Gerashchenko's post. These statements emerged in the context of Ukraine's earlier calls for global recruitment centers to bolster its forces, as noted by Advisor Flash around 11:00 UTC on March 1.
