An overview of the M118 round.

The M118 Full Metal Jacket Armor-Piercing[1] is a 7.62×51mm rifle cartridge commonly used in the United Nations Space Command's MA5 series of assault rifles.

Overview[edit]

The M118 FMJ-AP round is the standard-issue 7.62×51mm ammunition utilised by the the UNSC Armed Forces, with other options including shredder rounds. Its armor-piercing properties stem from its specially hardened construction.[2] During the Battle of Installation 04, it was commonly found in 120-round packs the possession of dead Marines or stockpiled on the ground wherever UNSC forces were engaged with the Covenant.

The following weapons in UNSC usage are chambered for 7.62×51mm ammunition and typically make use of M118 FMJ-AP rounds;

Performance[edit]

Weapons chambered for 7.62×51mm ammunition such as the MA5B assault rifle are considered to be powerful by UNSC soldiers.[2] UNSC infantry combat armor is capable of preventing lethal penetration at close range from a limited burst,[3] though infantry and even light vehicles or aircraft such as un-shielded Covenant Banshees are susceptible to fatal damage under sustained, accurate fire.[4] 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]
