They can, they respond to orders normally (attack orders in their small attack circle, self-D, fire state...).

Depends on the purpose, sometimes it behaves like one or the other. In some ways it behaves like neither (for example it has a ghost site, like a building, but it disappears immediately when it dies without requiring scouting, unlike proper buildings). In some, like a building (can't be thrown by Lobster/Newton or transported). In some, like a mobile unit (doesn't block terraform). It's a bit like asking if a mushroom is a plant (because it can't move) or an animal (because it's not green).
From a technical engine PoV it's an "immobile", which is a broader category that contains buildings, but has a bunch of exceptions to rules that normally affect immobiles.
