Advantages
The sniper rifle is designed to be used at medium to long ranges, and is equipped with a scope and night vision for precisely this purpose. With its 2x and 10x zooms and ability to penetrate Covenant shields, the sniper rifle is useful against distant Elites. A headshot against any Covenant infantry except a Zealot (Gold) Elite or Hunter results in an instant kill; Hunters fall from one shot to their unarmored torso or neck. When playing in the highest difficulty, Legendary, this is only true for Minor (blue) Elites; the Majors (red) will take two shots to the head, and the Zealots will take three. Also when night vision function is turned on (activated by pressing the flashlight button) one can see an invisible Elite very easily(note that in normal, easy, and heroic difficulties, the sniper rifle can kill pretty much an enemy in two shots as long as they hit the enemy [this doesn't include the Hunters' armor and the Jackals' energy shield]. When playing online, some players use the sniper rifle to great effect when camping.  For example, someone will crouch inside a confined hallway, and fire without the use of the scope from close range, resulting in an instant kill.

Disadvantages
The sniper rifle is almost impossible to aim at short range, due to the sticky-aim being removed when the scope is disabled and the paltry 4-shot magazine. It also has a steeper learning curve than most weapons, taking significant practice to master. Like any weapon, there is a need to lead targets if they are affected by internet lag, and it is hard to use at short range because its aim is so precise. Ammunition for this weapon is also quite rare. It is highly ineffective against all forms of Flood and against Sentinels. The only way that the sniper rifle can be effective against the flood is if you fire at thier arms, which will fall off leaving them harmless. The bullets leave a strong visible trail that can reveal the shooter's position to others. Though the cartridges would fit an anti-material rifle, the rifle performs poorly even against Ghosts, unless the pilot is shot, or the half-orb energy cell, (commonly mistaken for a "gas tank") on the left side of the ghost is shot. This is likely for balance reasons, since in First Strike a sniper round tears through a Covenant dropship.

Influence
The sniper rifle appears to heavily inspired by (if not directly copied from) the Barrett .50 caliber rifles (most notably the Barret M82 )and the South African NTW-20  including features such as the muzzle brake and futuristic angle design. The African rifle is chambered for both the 20mm x 83.5 round and the 14.5mm x 114 cartridge, while the Barrett fires a .50 BMG round. (note: a canadian sniper team had a confirmed 2400 yard kill in Afghanistan with the MacMillan Tac-50, a .50 BMG rifle similar to the Barrett 'Light Fifty'. There are reports that also state that high powered rifles such as the Barrett M82 can actually rip men in half, when using explosive ammunition. This, if anything, shows how underpowered the sniper rifle in the Halo games is, as it fires 14.5mm APFSDS projectiles, easily capable of tearing a hole through several sheets of steel, and commonly used as tank munitions in a much larger calibre.) Many of the features present in the Halo-version are included in both weapons, the recoil-dampening piston, the general look of the receiver; and for the Barrett the magazine placement, muzzle brake, and many other attributes such as the semi-automatic firing mode.



Appearences
The Sniper Rifle was featured in both Halo 1 and Halo 2. The original Halo Sniper Rifle had a digital radar-like view which was green. In Halo 2, the view was replaced with a visual image of the sniper's scope in real time. This weapon will return in Halo 3. How it behaves and other features have yet to be uncovered.
