Talk:Wall-mounted artillery

What is missing?
I have been questioning this lately. This article is marked as a incomplete article. My question is, does anybody know what is the missing information? Since I started on the wiki I put some edits here and there and completed the story. To sum up, what do you think it is missing on this article? And if nothing is missing, should we retire it from the category of incomplete articles? Have nice day :) Raposu (talk) 12:23, May 25, 2015 (UTC)Raposu
