It is not possible that robots Hp are dropping while attacking or being attacked.
Take the following points into consideration:
- Global Rebel Army Cross-Server, their Hp counter is shared between different servers, and It is not necessary to see the troop's routes because it may get attacked by another server.
- Some players use very powerful and sophisticated tanks in their attack to reduce the Hp of the robots.
- And others use Lone Wolf's ultimate skill (Special Ops), which helps to finish the attack immediately.
