And just how useful is it if it's also a secret to everyone in your own realm? Not useful at all is the answer.
I agree with Lilwolf, it makes no sense for SF special abilities to be completely opaque to the person leading them. Realistically, how are you *not* going to know what your unit can do? If they're more effective against fortifications, it's probably because they're lugging around cannons, bombs or other specialized siege equipment. Not exactly secret.
Well, it would be useful if, let's say, you're the only person in your realm knowing how they work
Although I suppose the real advantage would be rather slim. I think the compromise offered in the other topic might be okay: adding some flavour text giving a hint about their 'specialty'. Perhaps even during the construction of the RC. Kind of lameif you call your unit the Keplerstan Paladins if they are good at climbing fortifications...
