OK after I got done flying tonight I started thinking about this some more..

And I was wondering if this was something that could be programed into the system.

Basicly you have your normal spawns but a certain bases you have those red ones that could only be seen by the attacking country. Say knights would have 1 or 2 of these in Rookland and a couple in Bishland on the knight advance line that they could see and the same with the other countries.
So the idea is that if you work your way to the base where the line starts you then get the option to jump ahead on the line to what ever base it leads to, be it NOE mission or a conventional one. This would give you some advantage over your oponant if the capture was successfull.
It would also be nice if say the base was retaken by the original country the secret line would change starting and ending points so that it would be a surprise all the time and people would never know what base would be the secret target.
This might be a pain to program, I don't know because I'm not a programmer but I was just trying to think of a way to keep some of the sneaky missions in game. Otherwise the NME will always have some idea where you might attack.
Anyway just throwing ideas out here.

Oh BTW HT I fixed the missing arrow heads in the pic above.
