what is the secret army? the secret army is one troop you can put in watever you want only need to be in your territories.
what is so special in that ? the special is when you put then in your stack , you stack will change to neutral color but still yours and your opponent dont know if that troops are neutral troops or your troops , thats the funny , you can stay in you opponent castle (feudal example) barb 6 and he dont see you .
this special army can be deployed every turn , or only one time in the beghining and moved with the rest of the stack ,
if your opponent kill the stack with the army , your special army die and never more come back in that game ,
in maps with a lot of neutrals is gonna be fun play with this opption , imagine a surprise attack

please help me with your ideas and with your english


PS: you can only use this troop with fog of war
