1, suppose there are three players: A, B and C.
2. Player A can initiate the assembly to Player B or open the assembly to the hammer.
3. The system will automatically remove the soldiers who participated in the assembly from the base. For example, 100 soldiers participated in the assembly, and these 100 soldiers will be automatically removed by the system after the assembly starts, and will be returned by the system after the assembly is cancelled.
4. Player C flies to B, and the gains will not disappear.
The advantage of this method is that even if the base is attacked, the soldiers will not be eliminated because they are removed from the base by the system. This is a very effective strategy to protect soldiers.
