ok - I know I should know this but I don't
what is the deal w/all the different types of scanners?
you have the Long Range scanners that you can place on a ship/unit that can scan a ship/unit up to 5 spaces away depending on your tech level so long as the target doesn't have a scanner jammer.
but what do the Tachyon, Optic, Gravitational, EM, Passive, whatever components do? Why would you use those?
do they do something the Long Range scanner doesn't do?
