A 7.62x51mm cartridge.

The 7.62x51mm cartridge is an ammunition size in which the rifles and machine guns of the United Nations Space Command are commonly chambered. A significant variation of ammunition types for this cartridge are employed.

Overview

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 7.62 NATO.[1] The UNSC employ it in a wide variety of weapons, including:

Weapons chambered for 7.62×51mm ammunition, such as the MA5B assault rifle, are considered to be powerful by UNSC soldiers.[2]

Variants

M118 FMJ-AP

M118 FMJ-AP (full metal jacket, armor-piercing) rounds are the standard-issue ammo type employed by the UNSC's assault rifles,[3] the M392[4] and M395 DMRs,[5] and the M739 LMG.[6] The projectile's armor-piercing capabilities stem from its specially hardened construction.[2] 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,[7] though infantry and even light vehicles or aircraft such as un-shielded Covenant Banshees are susceptible to fatal damage under sustained, accurate fire.[8] 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.[2]

Shredder

Shredder rounds are an alternate 7.62x51mm ammunition type occasionally employed with the MA5B assault rifle.[9] The projectiles they fire are designed to splinter on impact,[10] and are highly effective against lightly-armored infantry like Covenant grunt soldiers[9] and building materials like marble tiles and wood.[11]

Hollow-point

7.62x51mm 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.[12]
