This ammunition shares its stated dimensions with a powerful cartridge developed in the 20th century by the Soviet Union, intended as an anti-materiel and machine gun round. The [[UNSC]] employ it in their own [[SRS99 series|anti-materiel sniper rifles]], which are highly effective when used to engage and destroy enemy equipment, vehicles and infantry, though the latter is not their intended primary function. It has been noted, however, that in an anti-personnel role, weapons firing this cartridge possess admirable performance against advanced [[Covenant]] [[energy shield]] technology.<ref name="EVG179">[[Halo: The Essential Visual Guide|'''Halo: The Essential Visual Guide''']], page 179</ref> While there exists a variety of ammunition types available in this cartridge, they tend to be highly damaging, precise and effective at long range.<ref>[[Halo: Combat Evolved|'''Halo: Combat Evolved''']]'', Gameplay''</ref><ref name="NightfallJun">[[Halo: Reach|'''Halo: Reach''']]'','' [[Nightfall|''Campaign level "Nightfall"'']]</ref>{{Ref/Reuse|H5GG}}

The 14.5×114mm APFSDS (armor-piercing, fin-stabilized, discarding sabot) round is the most commonly employed ammunition type for use with the [[SRS99 series]].{{Ref/Reuse|SFMp192}}{{Ref/Site|URL=https://www.halowaypoint.com/news/the-new-halo-encyclopedia-is-out-today|Site=Halo Waypoint|Page=The New Halo Encyclopedia is Out Today|D=11|M=03|Y=2023}} The round is easily capable of over-penetrating armored soldiers and whatever was behind them, making caution paramount when employing this ammo.<ref name="HCEM">'''[[Halo: Combat Evolved Manual]]''', ''page 18''</ref> The round is also highly potent at inflicting damage against light vehicles.<ref name="SFMp192">'''[[Halo: Official Spartan Field Manual]]''''', page 192''</ref> Ammunition of this type which was utilized in 2557 aboard the [[UNSC Infinity|UNSC ''Infinity'']] with the [[SRS99-S5 AM sniper rifle]] bore the alphanumeric designation "M232".<ref name="brief">'''Halo 4 Limited Edition''', UNSC ''Infinity'' Briefing Packet</ref>

The 14.5×114mm HVAP high-velocity armor-piercing round is an alternate ammunition type to the standard APFSDS which was used with [[SRS99-AM sniper rifle]]s during the [[Battle of Reach]]. According to [[Spartan]] [[Jun-A266]], the round is sufficient to "take the hat off an elite at 2,000 yards." He also implied that they were highly expensive.{{Ref/Reuse|NightfallJun}} During [[Blue Team]]'s mission to [[Reach]] in 2559, Spartan [[Linda-058]] used titanium-jacketed, depleted uranium HVAP rounds which proved capable of penetrating the energy shielding of [[Keepers of the One Freedom]] [[Seraph|Seraph fighters]].<ref name="SoR2">''[[Halo: Shadows of Reach]], Chapter 2''</ref>

The 14.5×114mm HEAP (high-explosive, armor piercing) round is used by [[Linda-058]] in her personal modified rifle ''[[Nornfang]]''.<ref name="LAL">[https://www.halowaypoint.com/en-us/community/blog-posts/canon-fodder-locke-load '''Halo Waypoint''' - ''Cannon Fodder: Locke & Load'']</ref> These rounds explode violently on impact, doing a great deal of damage to the target.<ref name="H5GG">'''[[Halo 5: Guardians]]''''', Warzone gameplay''</ref>

*The closest equivalent to an anti-material rifle using an APFSDS round, akin to the 14.5mm one of the SRS99, would be the 15.2x169mm APFSDS utilized in the prototype [[Wikipedia:Steyr_IWS_2000|Steyr IWS 2000]], which was the first hand-held weapon to use such a round.
