Going through the ITS12 missions, all of the missions which involve holding console at the end of a game have a stipulation that prevents deploying in silhouette contact with the console, except Safe Area.
Unless the missions specify that it's possible to deploy in contact with an objective, you are not allowed to. Still, seems like a small bit of oversight that could be added. https://infinitythewiki.com/Infiltrate?version=n4 REMEMBER Troopers cannot be deployed in contact with enemy and neutral Models, Markers, or Tokens, or in contact with any mission objective, no matter the Special Skills they have.
