Now that we can fortify units, It would be nice if on the following turns you would have an option to set a watch. Doing so would increase your sight radius by the movement of the units fortifying. Would represent patrolling that would naturally occur. The button for fortify could turn into a tower symbol or something, and if chosen a little wood platform could be added to the palisade graphic.
It should probably cost some materials 3-5 or so.
