The M79 is a 40 mm grenade launcher that remains unused by any faction in ArmA 2. It was added with the release of the Operation Arrowhead expansion pack.
Overview[]
The M79 is a single-shot grenade launcher with a break-action operation. It is designed to fire 40 mm grenade rounds.
It can only load 40 mm grenades that can be shared with M203/XM320 underbarrel grenade launchers.[CfgWp 5] The M79 can attain a fire rate of up to 120 rounds per minute[CfgWp 6][Formula 1] and has a simple leaf sight that can be used to aim with.
The M79 can load several types of grenade rounds with different kinds of warheads, ranging from basic high-explosive (HE), to coloured smoke, as well as flare shells for illumination and signalling purposes.
Like all other single-shot grenade launchers, the M79 must be reloaded after every shot, which significantly limits its fire rate. In addition, the operator is restricted to carrying an absolute maximum of eight grenades at all times (unless they choose to bring a backpack), which simultaneously prevents them from being able to carry magazines for a sidearm.
To make matters worse, the M79 is treated as a primary weapon[CfgWp 1] but uses ammunition that occupies secondary weapon slots.[CfgMa 2] On top of preventing the use of a sidearm since all of the slots are taken up by the M79's grenades, this prevents the user from being able to defend themselves if enemies get inside the M79's minimum range or if they run out of ammunition; whichever occurs first.
Needless to say, all these factors combined contribute to the M79 being a completely redundant weapon regardless of the situation. There is little reason to wield the M79 unless there's no alternative to using it.
Ironsights[]

The M79's leaf sight does not support manual zeroing adjustments.
When "aiming" in first person, the rear sight aperture approximately represents the point of impact for targets located 200 metres away.[note 1]

Trivia[]
- Along with the Sa-61 Scorpion, the M79 is one of the few weapons in ArmA 2 that remains unused by any in-game faction, though it can still be assigned to units through the use of scripting commands.
- Prior to the latest Steam version patches (as part of the Community Configuration Project updates), AI units that were issued the M79 were unable to aim properly. They would either miss their targets completely or refuse to fire the weapon. This was eventually fixed by the CCP's release, which added a unique hidden firemode that can only be utilised by the AI (this firemode "allows" them to shoot the M79 properly).[1]

Notes[]
- ↑ ArmA 2 does not natively support animated leaf sights on grenade launcher-type weapons. It is still technically possible to attack targets at distances greater than 200 metres, though it may be preferable to rely on the UI's crosshair instead if the latter is enabled in the player's difficulty settings.
