Noob Query re. phased v. continuous-play mode

[Steel God]

IN phased play in the ACW titles if you can not spot a unit when you open the turn than it is possible you will not spot it during the movement phase until you bump into it.  That statement is caveat-ed by saying if the moving unit is cavalry you will "spot" at two hexes.  If the moving unit is infantry with skirmishers deployed it will spot at 2 hex range.  In phased play when you "spot" you only get to know a unit is there, you don't know what it is until you advance the phase.  It's not quite as blinding as you may think since visibility on a clear day in an ACW title is 70 hexes, so you will see movement all over the place and allow you to focus your scouting in areas where you detect movement.  Also, with that 70 hex range watching the replays becomes important as lots of spotting happens passively on your opponents turn.
