As I understand it, 'Guard post' is supposed to imply 'structure that gets reinforcements'. Special forces guard posts do get reinforcements, so that's the correct name for them.
My point is: SF GP don't get regular reinforcements and are not guarded.
However, the reinforcement placement logic is broken (...) so that all regular reinforcements are placed at the command station. So, Wormhole Guard Posts should meet the definition but currently don't.
Okay. Good point.
