The Wall is your base’s first line of defense against attacks from other players in Last War Survival. You can assign up to 5 squads to defend the Wall.
When your base is under attack, the troops stationed there will take damage and may suffer losses. For beginners, it’s usually best not to place any squads in the Wall, as doing so can result in heavy troop losses.
