ALWAYS upgrade Rangers to Pathfinders. Rangers don’t exist. The ADDITIONAL +1 to cover on top of Stealth is worth at least an extra 10 points per model- you get it for 5, AS WELL AS MORE, most notably the +1 to the AP 1 roll when rolling to hit. Combined with the snipers always wounding anything on a 4 anyway, they can take on practically anything that is’nt a vehicle. Don’t forget to make your opponent roll for pinning checks! In buildings they have a 2+ cover save. Virtually indestructible scoring unit that will likely stay on the board firmly for the whole game.
