| | '''7.62x51mm NATO''' is a round used by the [[UNSC]] in many of their weapons. This round was originally developed by the [[NATO]] organazation in the 20th Century. This [[NATO]] round's main purpose was for fully automatic reliability and heavy power. |
| | ==Background== |
| | As it is used with the [[MA5]] rifles, which are one of the most common armaments in the [[UNSC Army|Army]] and [[UNSC Marine Corps|Marine Corps]], it is probably the most commonly fired and used round in the [[UNSC]] ground forces. |

| [[File:HINF M392Bandit Render 1.jpg|thumb|250px|An M392 Bandit and several M118 7.62x51mm FMJ-AP rounds.]] | | The round is quite effective in combat, as its mass makes it effective against flesh, however the round performs poorly against heavy armored and [[shield|shielded]] enemies. |
| This cartridge shares its dimensions with a form of rifle ammunition developed in the 20th century, employed commonly across the nations of the [[North Atlantic Treaty Organization]] under the designation [[Wikipedia:7.62x51mm NATO|7.62 NATO]]. The [[UNSC]] utilize it in an enormous variety of weapons, including:

| |
| ===M118 FMJ-AP===
| |
| M118 FMJ-AP ([[wikipedia:Full metal jacket (ammunition)|full metal jacket]], [[wikipedia:Armor-piercing bullet|armor-piercing]]) rounds are the standard-issue ammo type employed by the [[MA5 series|UNSC's assault rifles]],<ref name="EVGAR">[[Halo: The Essential Visual Guide]], Assault Rifle</ref> the [[M392]]<ref name="EVGDMR">[[Halo: The Essential Visual Guide]], DMR</ref> and [[M395]] DMRs,<ref name="H4VGDMR">[[Halo 4: The Essential Visual Guide]], DMR</ref> the [[M739 Light Machine Gun|M739 LMG]],<ref name="H4VGSAW">[[Halo 4: The Essential Visual Guide]], SAW</ref> and the [[AIE-486H Heavy Machine Gun|AIE-486H HMG]].{{Ref/Reuse|ENC331}} The projectile's armor-piercing capabilities stem from its specially hardened construction.<ref name= "Flood1">''[[Halo: The Flood]]'', Chapter 1</ref> [[UNSC Marine Corps Battle Dress Uniform|UNSC infantry combat armor]] is capable of preventing lethal penetration at close range from a limited burst at the cost of bruising and significant discomfort,<ref name="TML">''[[Halo: Evolutions]]'', ''[[The Mona Lisa]]'', section ">Lopez 1527 hours"</ref> though infantry and even light vehicles or aircraft such as un-shielded [[Covenant]] [[Banshees]] are susceptible to fatal damage under sustained, accurate fire.<ref name="Flood2">''[[Halo: The Flood]]'', ''Chapter 2''</ref> [[Energy shielding|Energy shields]] drastically reduce the ammunition's stopping power, as a great deal of concentrated fire from multiple weapons - or an extended period of continuous automatic fire from a single weapon - is needed to overwhelm them.<ref name= "Flood1"/> The rounds are, however, capable of taking down unprotected targets quickly and cleanly.<ref name="ENC316">''[[Halo Encyclopedia (2009 edition)|Halo Encyclopedia: The Definitive Guide to the Halo Universe (2011 edition)]]'', Page 316</ref>

| |
| | |
| ===Shredder===
| |
| Shredder rounds are an alternate 7.62×51mm ammunition type occasionally employed with the [[MA5B assault rifle]].<ref name="TFoRPrologue">''[[Halo: The Fall of Reach]]'', Prologue</ref> The projectiles they fire are designed to splinter on impact,<ref>''[[Halo: The Fall of Reach]]'', Chapter 29</ref> and are highly effective against lightly-armored infantry like [[Covenant]] [[Unggoy]]{{Ref/Reuse|TFoRPrologue}} and building materials like marble tiles and wood.<ref name="TFoR22">''[[Halo: The Fall of Reach]]'', Chapter 22</ref> Ammunition of this type was used by the [[SPARTAN-II]]s of [[Blue Team]] to engage a horde of Unggoy in the [[Battle of Jericho VII]].{{Ref/Reuse|TFoRPrologue}} Another instance of their use by Blue Team was at [[Cote d'Azur]], when engaging a pair of [[Mgalekgolo]] in a museum. After finding their AP rounds were ineffective against the Mgalekgolo's armor, [[John-117]] ordered the [[SPARTAN-IIs]] to use shredder rounds to fire at the floor beneath the Hunters, causing them to fall to the level below.{{Ref/Reuse|TFoR22}}

| | |
| ===Hollow-point===
| |
| 7.62×51mm [[wikipedia:Hollow-point bullet|hollow-point]] ammunition is a variant type of round which is optimal for use against unprotected biological targets, also employed occasionally in the [[MA5B]]. A situationally useful attribute of this ammo type is that it is unlikely to cause unwanted to damage to potentially vulnerable structures like equipment cabinets, viewports and [[starship]] hulls, making them a useful tool when taking a ship. Magazines containing this ammunition are recognizably marked with red paint.<ref>''[[Halo: Silent Storm]]'', Chapter 24</ref>

| ===AP-T===
| |
| 7.62mm AP-T ([[wikipedia:Armor-piercing bullet|armor-piercing]], [[wikipedia:Tracer ammunition|tracer]]) ammunition is employed in the [[M231 Medium Machine Gun|M231 MMG]] co-axially mounted on the [[M808B Scorpion]].{{Ref/Reuse|BnetVehicles}}

| | |
| ===HEDP===
| |
| 7.62mm HEDP (high-explosive dual-purpose) ammunition is a variant of the 7.62×51mm round which is loaded in the machine guns of [[ONI Wasp|AV-49 Wasps]] in the service of the [[Office of Naval Intelligence]] security teams.<ref name="CFBH">[https://www.halowaypoint.com/en-us/news/bounty-hunters ''Halo Waypoint'': Canon Fodder - Bounty Hunters]</ref> The projectiles detonate on impact.<ref>''[[Halo 5: Guardians]]'', [[Warzone]] gameplay</ref>
