The Ranger skills which are a quiet and deadly part of the Tier 3 class selection bring an unusual role to the battlefield. Typically not providing skills meant for close quarters battle, the Ranger depends on stealth and combat support in the form of summoned soldiers and air strikes.
How to become a Ranger - As we stated above, the Ranger is part of the Tier 3 class selection and requires you to follow the Soldier branch. When you gain enough experience to become level 5 you will receive a mission to find the Soldier and Specialist trainer. Choosing the Soldier branch will allow you to continue along until you receive enough experience for level 15 and will need to see a Commando or Ranger trainer. While Ranger trainers can be found at many locations, the most accessible is just outside the Foreas Command Center in Foreas Base. After training as a Ranger you will receive the following skills:
  • Ability: Reinforcements
  • Ability: Polarity Field
  • Ability: Carpet Bombing
  • Training: Stealth Body Armor
  • Training: Net Gun
Reinforcements - Utilize the power of Logos to tap into the Waypoint Network, bringing an ally on the battlefield to provide combat support. The ally cannot leave the area of translocation and once the abilities energy is expended the ally will return to base. Training in this skill allows more powerful allies to be called with each skill level.
What this means is you'll be able to summon a specific type of AI controlled soldier to assist you. Each pump designates the soldier you can call starting off with a fairly weak Pistoleer but progressing up to Rifleman, Medic, Grenadier, and even a Chaingunner. While a reinforcement will obviouslly never take the place of squadmate, they can come in handy by providing a little extra firepower and more importantly taking damage so you don't. This skill will prove to have more use to people who solo than frequent groupers.
You'll need to find the Friend Logos which can be found southeast of Nidu Dav at -762.1, 365.2 in Concordia Divide, the Summon Logos which is in a cave to the northeast of the Crossroads around 824.7, 156.0 , 512.1 (it requires Star, Friend, Here, Enlighten, and Life Logos to enter) also in Divide, and the Here Logos located in Daghda's Urn around -974.0, 284.0, 744.2 (it requires Power and Life Logos to enter).
Polarity Field - Polarity Field - Creates a field around the targeted enemy that performs quantum inversion in energy packets that cross its barrier. The inverted energy is able to easily bypass the target's defense systems. This has the effect of transforming the target's defenses into vulnerabilities.
This ability basically weakens enemies against certain weaponry types. If you are carrying a particularly powerful Laser rifle, why not make your target a lot more susceptible to it's damage? Armor on the enemy breaks down significantly faster when this skill is used. Higher pump levels will provide you with a variety of weaponry types to choose from and can also be of assistance to squads.
You'll need to find the Defend Logos which is at the top of the command tower at Foreas Base in Concordia Divide (you will be unable to access the tower without finishing a number of missions), the Transform Logos which is just north of the Nidu Dav village at - 470.8, 591.5, and the Negative Logos located between the Foxtrot Outpost and Foreas Base on top of a hill around 184.9, 119.9, 134.4.
Carpet Bombing - Create one of more beacons that teleport high-explosive bombs onto the battlefield. There is a slight delay between the creation of these beacons and the arrival of these bombs. Higher pump levels create more beacons; at higher pump levels Carpet Bombing will create a wide swath of destruction on the battlefield.
This is probably hands down the coolest ability Rangers get providing the power to call in an air strike at any time cutting a path of destruction. The unfortunate side of Carpet Bombing is the strikes not only take a few seconds to land, but cut a straight line providing only a small radial AE. When aligned properly however this can be devastating to a large crowd of hostiles. The more pumps your put in this skill the more area your air stikes will cover. The only other downside is each air stike costs Weapon Grade Micromech every time you utilize this skill.
You'll need to locate the Communication Logos in the Pravus Research Facility, the Area Logos in Imperial Valley around -432.2, -595.2, and Damage Logos.
Stealth Body Armor - Allows the use of Stealth Body Armor. Stealth Body Armor makes the wearer hard to detect at range. This semi-invisiblity is improved with better training and is based on the number of pieces of Stealth Body Armor worn.

Stealth Body Armor is one of the biggest benefits to being a Ranger and will carry over into the realm of Snipers and Spies. Allowing you to move in much closer, it will increase your survivability and assist you in avoiding unwanted encounters. Each pump in this skill will raise the effectiveness of the armor by 2% per skill providing a maximum of 10% per piece. This means you will be granted an additional 50% bonus to stealth, but what does that really mean?
It's still being debated honestly but most would agree at maximum pump you should be able to move within 20-30 meters of something completely unnoticed, further if you are behind it. This skill is pivotal for Spies as they have a "backstab" ability allowing them to do unbelievable damage.
Net Gun - Allows the use of Net Gun weapons. Net Guns entrap opponents, slowing or stopping their movement, while dealing out steady damage to them.
The Netgun is a interesting choice of weapon that will provide utility in a number of situations but not replace your staple weapons such as rifles or shotguns in light of their 3 round clip and 40m maximum range. The ability to "root" an enemy to its place can assist in escaping or slow down something you don't want so close. Having a limited damage type you'll be stuck with electric damage until you reach the early twenties to find fire and ice options. While the first pump of the skill only allows you to use them, additional pumps add a damage bonus of 10% per level up to a maximum of 40%.
Recent changes to the Netgun along with statements from NCsoft has indicated the weapon is intended to be "crowd control" meaning it is to be used for pining down creatures and managing groups. While this was a entire class in other fantasy MMO games, with the speed of Tabula Rasa combat this seems unmanageable. It does have it's uses at times so should not be ignored especially when the fire and ice damage types come along.
