I've been trying to understand submarines from discussions already posted before. However, information about subs is rather vague I believe.
I'm still having difficulties in understanding the following and I was hoping for someone to clarify that for me;
1. When do subs get spotted: Some say they get spotted by cruisers and Battleships once they enter their viewing range, is that true? Or is it that only when subs attack cruisers that they get spotted? Also, can balloons spot subs?
2. Do subs remain spotted after an attack? If yes, for how long?
3. Can subs be spotted when they get too close to other players' provinces. For example, if I have no relations with South USA (No right of way, and no share maps, just neutral), can they spot me if I get too close to their provinces as I'm scouting with the submarine? If the answer is yes, when do I get spotted? How close can I get?
4. How many fighters and also how many bombers does it take to kill a sub?
Thank you for your help, I very much appreciate it!
