The Context
On 5 May 2026, two civilians were killed and 35 injured in Cheboksary, Russia, by a Ukrainian drone strike. Twelve days later, a retaliatory Ukrainian drone offensive against Moscow killed three more and wounded 12, damaging numerous high-rise residential buildings. The UN Human Rights Monitoring Mission in Ukraine (HRMMU) documented that long-range weapons—including drones—caused 43% of all civilian casualties in April 2026, killing at least 84 and injuring 628. These are not battlefield accidents. They are the foreseeable consequence of a strategic choice to deploy long-range drones into densely populated urban areas without adequate distinction or precaution.
The Risk
Directors of entities that design, manufacture, supply, or integrate drone systems used in cross-border strikes face a direct and personal liability exposure under international humanitarian law (IHL). The UN has explicitly stated that striking civilians is a clear violation of IHL. Once UN findings—that long-range weapons in urban settings cause disproportionate civilian harm—are public, any continuation of such operations provides prosecutors with evidence that leaders were on notice. Under customary IHL and the doctrine of command responsibility, a director who authorises or materially enables drone operations that foreseeably kill civilians may be individually liable for war crimes. This is not a theoretical risk. The pattern is documented. The warning is recorded. The question is whether your board has an audit trail proving it took all feasible steps to prevent or cease such operations.
The Control
The strategic solution is not to withdraw from the sector. It is to implement a governance framework that ensures every drone system supplied or integrated is accompanied by a binding end-use assurance that prohibits use in urban cross-border strikes against civilian areas. That framework must include contractual clauses, independent verification, and a board-level escalation protocol for any breach. Without it, your company is a knowing contributor to operations with an established record of civilian casualties.
The Challenge
These are the critical questions you should be raising at the board table:
| What documented assurance do we have that our drone systems are not being used in cross-border strikes against civilian areas in Russia? | |
| Have we conducted a due diligence review of our supply chain to identify any end-user that may be using our technology in a manner that violates IHL? | |
| What is our board-level escalation protocol if we receive credible evidence that our systems are being used to cause civilian casualties? |
