Ukraine has revived one of the oldest tactics of war — and is isolating Russian cities without needing soldiers

Ukraine is reviving siege warfare with drones, targeting roads, convoys, and logistics hubs to cut supply lines to occupied cities like Mariupol.

It is also using long-range drone strikes against Russia, including areas near Moscow, forcing air defenses to spread out and absorb constant costs.

The strategy turns logistics into a primary battlefield and enables isolation and attrition without large-scale ground assaults.

This reflects how drones are reshaping war by making supply chains and infrastructure central targets.
