Strategic Integration: The Ukrainian Expeditionary Corps as the Expert Nucleus of the European Army.

This document provides a technical‑operational expansion of the plan Towards a United European Army (DOI: 10.5281/zenodo.17350350). It proposes the integration of up to 50,000 Ukrainian veteran soldiers as the expert nucleus and permanent training corps of the future European Army, significantly accelerating the EU’s Readiness 2030 objectives.

The proposal introduces a tripartite force structure composed of:  
- a 20,000‑soldier Permanent Expert Nucleus, forming the immediately deployable backbone of the European Army;  
- a 30,000‑soldier Training & Doctrine Corps, responsible for doctrinal development and the training of all European recruits;  
- 100,000 European recruits, selected according to demographic quotas and trained through a unified curriculum.

The document outlines a comprehensive integration framework including:  
- a Common Core Curriculum focused on hybrid warfare, EW, counter‑drone operations, and artillery‑survival tactics;  
- an Operational Evaluation Centre in Ukraine for testing MARTE, ENGRT and SAMP/T NG systems in realistic conditions;  
- an EU Hybrid Warfare Centre (HYBRIDEX) with 10,000 cyber specialists;  
- a phased legal roadmap based on PESCO;  
- a sustainable financing model combining ReArm EU and the Ukraine Facility.

The proposal transforms Ukrainian battlefield experience into a strategic European asset, reducing readiness timelines by 5–10 years and establishing a structural security bond between the EU and Ukraine.
