Here are the ways to deal with enemy structures:
* Destroy them: This is the most common way to deal with enemy structures. You can use your units' weapons, artillery strikes, or even special abilities to take them down.
* Bypass them: Sometimes, it's more efficient to ignore enemy structures and focus on attacking their units directly. You can use your units' mobility and your map knowledge to avoid them.
* Use flanking maneuvers: Attacking an enemy structure from the side or rear can be more effective than a frontal assault. This way you can avoid enemy defenses and take them out quickly.
* Exploit weaknesses: Some structures have weaknesses that can be exploited. For example, some structures are vulnerable to air attack, while others are easily destroyed by heavy weapons.
Remember, the best strategy will vary depending on the situation, the enemy's forces, and the type of structures you're facing.
