So, on page 96, the rules for gun emplacements all refer to being mounted on/in a building. Obviously, the aegis shield wall is not a building, it is a battle field debris (Defence Line).
There are also rules for battlefield debris gun emplacements(pg 105), which do not have automatic fire, only manual fire. I would like for the aegis shield walls gun emplacement to have automatic fire like the other buildings, but it doesn't look that way. Since the aegis shield wall is not a building, and the gun should be targetable I have to think we are meant to use those rules for it (has a statline also, same as artillery)
Anyway, I was just wondering how other people were planning on playing it and if I had missed something somewhere. I was considering using a shield line with my nid army but primarily for anti-air fire (i know lots of people were) but it doesn't seem to work
