The war in Ukraine has seen a surge in foreign volunteers joining the fight against Russian-backed separatists. However, with no formal structure for vetting volunteers, individuals with problematic pasts and fabricated military records have become entrenched in the International Legion and other volunteer groups. This has led to unchecked access to weapons and military equipment, posing a significant risk to the safety and security of those involved in the conflict. Formal structures for vetting volunteers are crucial to ensuring that only qualified individuals have access to weapons and military equipment.
