US Treasury official stated basis is previous agreement (Feb), Trump claims final signing next week (Apr 24). Aims to facilitate US investment.
Leadership Changes:
Sumy OMA: Head Volodymyr Artyukh dismissed. Dismissal confirmed by Presidential decree. Russian sources (TASS) claim dismissal linked to fallout from Apr 13 RU strike on alleged military meeting. Oleh Hryhorov appointed.
Luhansk OMA:Oleksiy Kharchenko appointed.
Kherson MVA: Head Roman Mrochko dismissed. Dismissal confirmed by Presidential decree dated Apr 17.
Drone/Equipment Needs: Multiple units continue fundraising appeals (FPVs, Mavic recon, vehicle repair), citing high operational tempo and RU activity.
B. Russian Capabilities & Developments
Logistics/Morale: Continued reliance on volunteer aid (e.g., MOO Veche supplying marines with tactical medicine/gear). Fundraising appeal for basic evacuation vehicles (UAZ) on high-intensity Pokrovsk axis indicates potential shortfalls. RU milbloggers report command discourages public unit identification in aid requests, hindering support. RU source claims UA command prohibits evacuating non-ambulatory wounded (potential LOAC issue/propaganda).
Advanced Systems: Use of Tornado-S MLRS, Iskander missiles, ODAB/FAB-1500 UMPK bombs highlighted. MoD RU promotes Grad/Uragan MLRS use.
Internal Issues: Kursk corruption investigation ongoing. Report of 810th Naval Infantry Brigade servicemember arrested for alleged double murder (Stary Oskol).

Paris Ceasefire Talks (Apr 17):
High-level meeting (UA/US/FRA/UK/GER) described as "positive and constructive" (France). US State Dept stated results show peace is possible.
Next round planned for London next week.

Rubio reportedly informed Lavrov of Paris talks; stated Trump seeks swift end to conflict. Lavrov confirmed RU readiness to work with US on "root causes." Agreement to maintain communication.
Ukrainian Position (Yermak): Only acceptable Putin response is support for complete ceasefire and agreement on control/monitoring mechanism and humanitarian track. Ukraine reportedly agreed ceasefire should be first step (per RU source citing Yermak).
RU MFA: Claimed "progress" in US dialogue.
US State Dept: Stated "encouraging reception" of US concepts in Paris shows peace is possible if all parties seek agreement.
