@H20 Moodoo yes, people often take their heroes into the forest with a full army, so that if their castle is burned while they sleep, they at least have something with which to farm or fight back the next day.
Mind you, this does not work if they are an adjacent forest tile. They will be discovered and destroyed. They need to go camping somewhere.
ask them, currently there are no such game mechanics that hide troops at certain locations but people tend to flee with a hero with troops attached to them if you attack, thats why you should keep a hero outside town and send them in last seconds
there are games out there where you hide troops check your source and knoledge im a long time gamer played 100s of games anyway hideing troops for this game you throw all ya good troops on your heroes and stick them in a forest theres another way but thats telling you how i do it and i can hide thousands
