With having played this game for awhile I've come to realize that it's very tricky trying to place my artillery or anti-tank guns into a good firing positions before either a enemy unit or turret takes them out. I think if possible ranged units should have a ring around them, when selected, that shows what the ranged units firig range is especially since they are so slow that by the time you get them into a good position they have already taken damage or Ive loser a few units. I don't know about anyone else preference but I think it would be help full if there was some type of range indicator
