Home Spawn Point (or Home Base) is the technical term for all Base types where players can respawn if they've set their spawn there but also deploy to from Home Region. Players can also build Cranes and Construction Vehicles next to it.
You can only deploy there if the base's Garrison Size isn't zero. Garrison Size and Garrison Activity of those bases can be checked by putting your cursor on the base's icon on the map when in the world.
On the deployment menu, Home Spawn Points appear as black diamonds whose size represents their Garrison Size.
Players can have one spawn set to a Home Spawn Point and another to a Forward Spawn Point.
