Guard Post

Overview
The Guard Post is basically a slightly upgraded Bunker with no other benefits to speak of. It needs a little bit of Steel and  Concrete to build. It can hold 15 soldiers and no vehicles, and appears to have a defense radius a tiny bit bigger than that of a Cannon Tower.

The in-game description used to be bugged and misleading, saying that it has a defense radius of 0 and implying that it is a defensive structure more like a Pillbox than a Bunker, but more recent patches have fixed that issue.

The player is required to build a Guard Post at one point during the Crazy Blades mission sequence.
