GLA hole

A GLA Hole would be left behind if a Generals:GLA building was destroyed. From within the Hole a Worker could emerge to rebuild the building in question. The Worker that performed this task disappeared back into the Hole (and presumably the GLA Tunnel Network after construction.

Enemy commanders had to be careful to remove the GLA Hole each time they destroyed a GLA structure, or the hard work of their troops would be undone.
