Problem using land units in missions
 

Folks - am testing some potential missions for the TSWSM and have created a test mission with some land based coastal bunkers...... I envisage some campaign missions where surface ships support the landings by taking out land based targets... I thought I'd start witht the coastal guns as a test.

Problem I have is the units get spotted by my deck watch, and I can see them in free cam and via binoculars .... but I can not target them with deck gun. Anyone know how these units work ? Are they just there to shoot at you and you have no way to target them ?
