The Kraber fires a unique round that ensures 'one-shot,one-kill' results against human-scale targets. However, considerable judgement in leading is required, making this a difficult weapon to use against moving targets.
The Kraber-AP is a straight-pull bolt-action sniper rifle with a side-mounted magazine. As expected from its large-caliber 14.5x114mm rounds, it has unparalleled damage amongst Pilot weapons, able to kill any infantry in one shot at any range. Pilots must lead against moving targets due to the long projectile travel time between the shot and impact (slightly faster bullet speed than rounds from the 40mm Cannon) of the weapon's projectiles.
This one-shot-kill weapon is great for long-range fights, but if you get really confident with the weapon, you can be a threat mid-range with a well-placed shot on enemy Pilots.
This weapon is difficult to snipe Pilots with when they are wall running and double jumping—try to catch them off-guard when they are on top of a roof. Distance is your friend when you are sniping. Get in a elevated perch away from danger so you can pick off enemy Pilots without the risk of dying. Keep in mind that you have to lead your shot due to the weapon’s low bullet velocity. If enemy Pilots are sniping or holding a static position, this is the weapon to take them out with.
If your goal is to take out minions, this is not the best weapon. With the slowest rate of fire and smallest magazine capacity, this gun is mainly an anti-Pilot weapon.
If you want to sit back and support, be sure to use the default 6X Zoom Scope or the 4.5X Zoom Scope and find the highest perch available. If you want to move up with your team and be a mid-range threat, equip the AOG scope along with a Suppressor to conceal your position.
The Supressor attachment removes the Kraber's one-shot potential, making it almost completely useless and requiring a pilot to land at least two shots to kill. It is highly recommended not to use this attachment.
The AOG, or Advanced Optical Gunsight, is fixed at 2.4X magnification, and includes an integrated "current magazine capacity" readout with a backup numerical display. The AOG is ideal for combat at extended range.
The Kraber is an exceptionally bulky weapon and it handles as such, with slow weapon handling and long reload times. It does however have immense power, in that it is capable of outright killing any human-size enemy with a single round.
Rounds fired by this weapon have a considerable arc and travel time, both of which must be taken into account beyond close range engagements.
It takes true skill to effectively wield a Kraber, and it is this trait that endears the rifle to many players.
In general, the Kraber is used with a pistol sidearm rather hang the conventional AT weapon, as pilots are extremely vulnerable in CQB should they eschew such a weapon. It is worth noting that if you are able to overcome this problem, an AT weapon will make you a versatile and lethal force, capable of slaughtering all foes. As of The War Games, players can now wield an AT weapon and a sidearm at the same time, so player's opting for the Kraber will always have a CQC option in their arsenal.
Parkour will greatly hinder the accuracy of this weapon, so it is advisable to remain fairly still when aiming the weapon. Relocating between shots will allow you to get the drop on your opponent, making shots much easier to land.
The Kraber's name is a reference to Erik Kraber, the audio lead of Titanfall.
The weapon is most likely based off the South African NTW-20 and the Indian Vidhwansak, both are multi-calibers (using 12,7x108, 14,5x114 and various 20mm shells) anti-materiel rifles. Besides the incredible size of the rifle, the most distinct shared trait is the side-mounted magazine, an oddity among other weapons of its type. Concept art also describes the weapon as being inspired from competition shooting rifles.
The Kraber is the strongest weapon in both Titanfall 1 and 2 being the only weapon to have 100 damage per shot.
According to Grunt chatter, academy training includes target practice with the Kraber, firing at parasites on Behemoths. Despite this, no AI forces ever deploy with Krabers.
Despite being called an Armor Piercing rifle, the Kraber can not penetrate a Titan's armor without hitting the weak spots highlighted in red.
