# Main Topic
**Operation Vivaldi:** A coordinated Ukrainian counter-offensive and active defense campaign targeting Russian occupation forces in the Lyman sector of Donetsk Oblast.
## Key Points
- **Significant Attrition:** Over 10,660 Russian troops reported killed or wounded in a single week (late September 2026).
- **Territorial Gains:** Ukrainian 3rd Army Corps retook 40 square kilometers and several villages in northern Donetsk Oblast.
- **Evidence-Based Reporting:** Ukrainian command claims video verification for all documented Russian losses during this period.
- **Operational Secrecy:** Operation Vivaldi remained classified from late spring 2026 until mid-September 2026 to maintain tactical surprise.
## Threat Actors
- **Russian Armed Forces:** Primary kinetic threat actor occupying Ukrainian territory.
- **Occupation Collaborators:** 44 individuals sanctioned for facilitating Russian political control through illegal elections.
- **North Korean Elements:** Identified through the presence of North Korean POWs, suggesting active foreign military support for Russian operations.
## TTPs
- **Active Defense:** Utilizing Air Assault Forces to disrupt Russian offensive momentum while conducting localized counter-attacks.
- **Information Obfuscation:** Keeping specific offensive operations (like Vivaldi) out of official communiqués for months to evade OSINT and Russian intelligence tracking.
- **Droning and Technical Surveillance:** Use of elite drone units to monitor and control highways in occupied regions (e.g., Crimea).
- **Political Subversion:** Holding sham elections in occupied territories to legitimize territorial claims.
## Affected Systems
- **Geographic Sectors:** Lyman, Pokrovsk, Kostiantynivka (Donetsk Oblast); Zaporizhzhia, Kharkiv, and Sumy oblasts.
- **Logistics/Infrastructure:** Highways in Russian-occupied Crimea targeted by Ukrainian drone units.
- **Information Integrity:** Breach of confidentiality regarding POW transfers impacting South Korean-Ukrainian diplomatic intelligence agreements.
## Mitigations
- **Kinetic Neutralization:** Continued elimination of occupying forces through coordinated ground and air assaults.
- **Economic & Diplomatic Sanctions:** Targeting individuals facilitating the occupation and administrative infrastructure of the adversary.
- **OPSEC (Operations Security):** Delaying public disclosure of military operations to protect personnel and objectives.
- **Technical Adaptation:** Rapid evolution of drone tactics to stay ahead of Russian electronic warfare and physical adaptations.
## Conclusion
The threat landscape is currently dominated by high-intensity kinetic warfare in Eastern Ukraine. The success of "Operation Vivaldi" suggests that Ukrainian forces have maintained operational surprise despite prolonged OSINT monitoring. However, the reported disclosure of North Korean POW movements indicates a potential friction point in international intelligence sharing. Organizations should monitor for increased Russian mobilization and potential retaliatory cyber or kinetic actions following these significant personnel losses.
