ArmA: Cold War Assault

« The M16 Assault Rifle series of weapons developed from research conducted by the U.S. Army's Operations Research Office (ORO), created at Johns Hopkins University in September 1948. As the United States Army's standard-issue rifle, the M16 is a reliable and accurate weapon (although prone to jamming, as it's relatively easy for dirt to get into the chamber and magazine).

The M16A2 5.56 mm assault rifle.

The M16A2 is used exclusively by U.S. military forces in ArmA: Cold War Assault.

Overview

The M16A2 is a gas operated, selective fire assault rifle that is chambered to fire the 5.56×45 mm NATO round.

It loads from 30-round magazines and can attain a fire rate of up to 857 rounds per minute, with a muzzle velocity of 990 m/s. It has an effective range of up to 450 metres.

The M16A2 was the standard issue service weapon of the U.S. Armed Forces at the height of the Malden Islands Crisis. Along with its Soviet counterpart, it is one of the two staple weapons that can be used in Cold War Assault.

U.S. grenadier armed with the UGL-equipped M16A2.

However, compared to the AK-74's 5.45 mm round, the M16A2's 5.56 mm NATO retains better ballistics when the weapon is fired in at medium-long ranges. The M16A2 is also able to (unique to both the M16A2 and the XM-177E2) launch rifle grenades from its muzzle.

In terms of drawbacks, the M16A2's main weakness is its lack of a full auto mode as the M16A2 is restricted to toggling between semi-auto and 3-round burst fire.

This makes it comparatively less effective in close quarters since the AK-74's shooter will always be able to fire without interruption (even if they miss). In contrast, the M16A2's operator will be left vulnerable for a split second if they miss their initial burst.

The M16A2 GL is a modified version of the baseline M16A2 rifle that has an underbarrel grenade launcher fitted onto it.

While identical in most aspects, the M16A2 GL's sole downside is that it cannot utilise its parent weapon's ability to fire rifle grenades from the muzzle; though it's not necessarily a downside given that it already has an underbarrel grenade launcher to begin with.

The M16A2's M203 grenade launcher can launch either high-explosive (HE) or flare rounds, and is accurate at distances of up 250 metres away.

Both variants of the M16A2 only support a single type of magazine. It requires one free inventory slot to carry:

30-round magazine loaded with 5.56 mm ball ammunition.


Trivia

  • Although technically not anachronistic, the M16A2 didn't actually begin replacing the M16A1 in U.S. Army service until the late 1980s. Prior to this, it was only used by the U.S. Marine Corps (U.S. forces in Cold War Assault predominately consist of units from the Army).

ArmA: Armed Assault

« The M16 assault rifle entered service in 1965 at the onset of the Vietnam War. It answered the army's need to replace the ill-suited M14 with a lightweight rifle capable of effective automatic fire.
The M16 uses a small, high velocity round with low recoil and good armor penetration, effective to about 500m. After numerous improvements and upgrades throughout its lifespan, the M16A2 remains in service today as the army's basic service rifle.

The M16A2 5.56 mm assault rifle.

The M16A2 is used by both RACS military forces and Black Element PMCs in ArmA: Armed Assault.

Overview

The M16A2 returns from Cold War Assault and serves as a general-purpose 5.56 mm assault rifle.

It can now load from either 20-round box or 30-round STANAG magazines, has a muzzle velocity of 850 m/s, and can only attain fire rate of 600 RPM. The M16A2 is not available in any variant fitted with optical sights/muzzle attachments.

Armed Assault's M16A2 is the primary service rifle of the Royal Army Corps of Sahrani, and is similar role-wise to the Russian AK-74 wielded by their SLA counterparts. However, the M16A2's actual performance leaves much to be desired, and comparatively inferior when matched against its modernised counterpart and the G36 family.

Since it cannot be fitted with optical sights (both attached and integrated), this limits the M16A2 to a maximum effective range of just 400 metres. Beyond that distance, the M16A2's ironsights are too cumbersome to reliably hit targets with.

The M16A2 + M203 5.56 mm assault rifle.

The M16A2 + M203 is a modified version of the baseline M16A2 rifle that has had an underbarrel grenade launcher fitted onto it.

The M16A2 + M203 is only wielded by RACS grenadier soldiers, and has no functional or performance differences from its parent weapon.

The M203 is capable of launching either conventional high-explosive (HE) grenades or illumination/signal flare shells. It has a leaf sight that is accurate at distances of up to 300 metres.

Trivia

  • On release, Armed Assault's M16A2s had an unrealistically low fire rate of just 400 rounds per minute. This was later corrected to 600 RPM after the release of Patch 1.14, and is also adjusted correctly by default in the Gold version of the game.

The M16A2 5.56 mm assault rifle.

The M16A2 is used by both the Takistani Army and anti-government rebels in ArmA 2.

Overview

Once again returning in ArmA 2, the M16A2 is now used by several more factions but functionally remains the same as its predecessors.

It still loads from either 20-round box or 30-round STANAG magazines shared by its modern counterpart, and is able to attain a fire rate of up to 800 RPM on burst. The M16A2 does not come in any variant that has either optical accessories or muzzle attachments fitted to it.

Identical to its predecessor in Armed Assault, the M16A2 is often wielded as an alternate primary weapon alongside the heavier FAL battle rifle carried by most Takistani soldiers.

Compared to its Russian-made counterpart, the M16A2 has better ironsights with a slimmer aiming post which makes it easier to aim at targets at distances of up to 400 metres away. The M16A2's use of 5.56 mm also allows it to share ammunition with modern assault rifles like the M4 carbine, or even the SCAR family of modular weapons.

Its lack of modularity does mean that isn't nearly as useful compared to other modern rifles though, as is its inability to fire on full auto. Since it doesn't feature any variants fitted with suppressors, the M16A2 is also useless for missions that require stealth.

It is wielded by some ION PMC contractors operating in Takistan, but is otherwise used only by the Takistani Army and anti-government rebels.

Like its parent, it is also chambered to fire the same 5.56 mm NATO round, but has an underbarrel grenade launcher that can fire 40 mm grenades. It is otherwise completely identical in terms of stats and handling.

The M203 has a conventional leaf sight that is accurate at ranges of up to 300 metres.

30rnd G36 SD

Trivia

  • ArmA 2 is the first game in the series to feature the M16A2 as a REDFOR weapon rather than BLUFOR or a BLUFOR-aligned INDFOR faction.
    • Some USMC units can still be seen wielding the M16A2 in the early stages of the Operation Harvest Red campaign. However, none of their units actually utilise the M16A2 in regular gameplay.
  • Like the G36 and XM8 assault rifles, the M16A2 was actually available in ArmA 2 first but would remain unused by any in-game faction until the release of Operation Arrowhead.

The M16A2 5.56 mm assault rifle.

The M16A2 is used exclusively by U.S. military forces in ARMA Reforger.

Overview

This section is a stub. You can help Armed Assault Wiki by expanding it.

A selective-fire assault rifle, Reforger's M16A2 returns as the standard-issue service weapon of all U.S. military forces.

Unlike its predecessor in ArmA 2, it can only load two types of 30-round STANAG magazines. Its muzzle velocity and fire rate remain unchanged at 930 m/s and 800 RPM (respectively).

The M16A2 is still unable to mount optical sights and cannot be suppressed with muzzle attachments. However, the carryhandle's sights do allow for manual zeroing. Starting at a minimum of 200 m it can be zeroed up to a maximum of 800 m, with adjustments being made in 100 m increments/decrements.

Additionally, the M16A2 can be fitted with the M203 underbarrel grenade launcher. It requires replacing the barrel's handguard with a dedicated heat shield and the M203 itself.

M16A2s are limited to loading two types of magazines. They are not interchangeable with other 5.56 mm-chambered weapons:

5.56×45mm 30rnd STANAG Mag

Reforger-ammunition-30rndstanag.png

30-round STANAG magazine loaded with a mix of M855 ball and M856 tracer ammunition (with a 25/5 split). Only the last five rounds of the magazine comprise of visible tracers.

It has a weight of 0.120 kg and occupies 1x1 inventory slots with a volume of 200 cm3.

5.56×45mm 30rnd STANAG Tracer Mag

Reforger-ammunition-30rndstanag.png

Dedicated tracer magazine loaded exclusively with M856 tracers.

It shares the same weight, inventory slot layout, and volume space requirements with standard 30-round STANAGs.


Trivia

  • When firing on burst mode, Reforger accurately simulates the M16A2's burst trigger memory "flaw" whereby if the user interrupts the 3-round burst early, the next burst will only fire the remainder of the previous burst's rounds (i.e. user fires two rounds, halts, and then fires only one round for the next burst).
  • Amusingly, if the M203 is removed on M16A2s that already have one attached by default (thereby leaving the barrel exposed), the user's hands will continue to grip the M16A2's invisible handguard as if it were still present.
The information below details unused, pre-release or removed content.
  • There is an unused M16A2 variant that exists within the game files (Entity name: Rifle_M16A2_4x20).
    • Based on its naming scheme, it is presumably intended to be an M16A2 fitted with the Colt "4x20 Carry Handle Scope". However, the scope itself does not actually exist as an attachment.
