Let´s say that I made contact with a High Density Task Force, and after revealing the boats I have no way to shoot. I know by 14.16 that I can forfeit the attack and retreat, but I am not sure if I need to make the resistance check to stay at sea (the rulebook says: after a round of combat.
The same if I make the contact check and get "no contact". Or if I avoid the search and contact.
As there is a -1 mod if I do not make contact or search, I am checking to everyone, but I want to be sure. It´s difficult like hell mantain the subs at sea !
