In a war for resources, destroying the opponent's supply lines is an effective strategy to weaken their combat effectiveness. Here are some methods: 1. **Intelligence gathering**: Understand the opponent's supply routes, supply points and transportation methods in order to carry out targeted destruction. 2. **Destruction of key transportation routes**: Attack or destroy key transportation infrastructure such as bridges, roads and railways, making it impossible for the opponent's supplies to be delivered smoothly. 3. **Cyber attacks**: Paralyze the opponent's logistics system through cyber attacks, causing chaos in transportation scheduling and management. 4. **Ambush operations**: Set up an ambush on the road where the supply convoy passes and cut off its material transportation. 5. **Maritime blockade**: If the opponent relies on sea transportation for supplies, a maritime blockade can be implemented to intercept the supply ships. 6. **Air strikes**: Use the air force advantage to carry out precision strikes on supply stations and transport aircraft. 7. **Spreading false intelligence**: Let the opponent misjudge the security of the supply route, so as to relax its defense or change the route, exposing itself to greater risks. 8. **Guerrilla tactics**: Send small groups of troops to sabotage and harass the opponent's rear, increasing the difficulty of supply. 9. **Blockade of resource sources**: Directly capture or block the opponent's important sources of resources and materials, cutting off the source of the supply chain. The implementation of these strategies requires full consideration of one's own capabilities and resources, while paying attention to the opponent's possible countermeasures.
