With the Manirak rift open, the need for people who can live off the land for extended periods of time has become paramount.
As superb marksmen and survival experts, the Rangers are the obvious choice for any extended mission. Their camouflage skills allow them to stage ambushes along communication and supply routes and execute them with ruthless efficiency.
As more and more enemy forces were mustered up, an elite group of rangers started to experiment with explosives (mostly mines) as a force multiplier.
The success of these new ambush tactics has led to the rapid development of new, deadlier explosives. Unlike mines, the new devices were light enough to be launched by a heavy crossbow. These elite Ranger units are now known as Grenadiers.
