A 14.5mm APFSDS round.

The 14.5x114mm Armor Piercing Fin Stabilized Discarding Sabot bullet is used by the UNSC's Sniper Rifle System 99C-Series 2 Anti-Matériel and Sniper Rifle System 99D-Series 2 Anti-Matériel.

BackgroundEdit

Possibly similar to an ammunition type employed by the Soviet Union during the twentieth century, the round is employed in an anti-matériel role, used to damage or destroy enemy equipment and vehicles. However, thick Covenant armor, and the use of Energy Shields by Sangheili and Kig-Yar, has caused it to take on an anti-personnel role in addition to its anti-armor roles.[1][2]

The 14.5mm sniper round has less effect on living targets due to the ammunition type. These are designed for penetration and not terminal performance; this type of bullet does not fragment nor does it tumble, which would cause maximum damage to a target but instead punches through with extreme velocity, so the actual wound it creates is rather unimpressive, at least compared to that of a weapon firing rounds that would tumble or fragment. This is generally not a concern against any but the hardiest of creatures or those with bodies well suited to handling the forces involved without grievous injury, such as Mgalekgolo, as the sheer force of such a round should still be sufficient to create an impact capable of blowing off human limbs at most ranges. APFSDS rounds were originally intended for use in armor vehicle main weapons (IE 90mm-120mm smoothbore guns) to defeat armored vehicles due to the increasingly ineffectiveness of HEAT and HESH shells against modern armor, though many other large caliber weapons have seen use with it.

TriviaEdit

  • The 14.5x114mm round is actually a Russian heavy machine gun round that was developed for use in anti-tank rifles like the PTRD and PTRS in World War II, later used in anti-aircraft and vehicle mounted roles with the KPV; it remains in use to this day.[3]
  • Its armor piercing capability is evident when a single bullet fires through multiple Spartans and Sangheili with full Energy Shields.
  • The round bears striking similarity to the 14.5 and 15.2mm APFSDS rounds developed by Steyr-Mannlicher AG & Co KG in the mid 1980s for their AMR 5075 and IWS 2000 sniper weapons.[4]
  • This type of round is a .57 caliber, much bigger than the 12.7x99mm (.50 BMG) the M41 LAAG uses.
