Hand Grenades are throwable explosive devices.

Throughout the series, hand grenades have appeared in various forms and always serve as auxiliary pieces of equipment for infantry units. They are always thrown and in most cases, must also be manually primed whereupon they will detonate after a few seconds.

Hand grenades are mostly fragmentation-based though some grenades are of a high-explosive (HE) type instead. They are highly lethal against unarmoured infantry and will damage (or disable) lightly armoured vehicles easily as well.

However, their splash radius is minimal and much smaller compared to explosive-based munitions fired by vehicle cannons or shoulder-carried launchers loaded with anti-personnel rounds.

NOTE: Hand grenades should not be confused with the rifle grenades launched by specific firearms like the M16A2 in ArmA: Cold War Assault, nor those fired by underbarrel grenade launchers fitted to assault rifles such as the MX in ArmA 3.

ArmA: Cold War Assault

Cold War Assault-era hand grenade

« A Hand Grenade can be thrown 130ft/40m by the average soldier, and is a standard battlefield weapon.

In ArmA: Cold War Assault, hand grenades are standard issue for both U.S. and Soviet troops. Almost every soldier carries at least 4-6 grenades.

Grenades in Cold War Assault must be manually cycled and primed by their user, though the user can adjust the "strength" of their throw which will in turn affect how far the grenade gets thrown. Grenades always detonate on impact and inflict damage in a blast radius of 7 metres, so caution is advised when using them near friendly forces.

ArmA: Armed Assault

Armed Assault-era hand grenades

« Soviet defensive, impact fused frag grenade. It weights 530g and can be thrown 30 to 40 meters, with a lethal radius of 6 meters on impact.

The body of the M-67 hand grenade is a sphere designed to burst into numerous fragments when detonated. Each grenade is fitted with a 5 second fuse which activates the explosive charge.

RGO 20 7

In ArmA: Armed Assault, hand grenades are now available in two variants: the Russian-made RGO exclusive to the SLA and American-made M67 Frags used by both U.S. Army and RACS forces.

Both grenades have an identical damage output and have a kill zone radius of 7 metres. The sole difference between them is how they detonate after being thrown. The RGO is an impact grenade that detonates instantly on landing just like its predecessor in Cold War Assault. The M67 Frag on the other hand, will only explode five seconds after being thrown.

ArmA 2

ArmA 2-era hand grenades

« The timed anti-personel fragmentation grenade. Explodes 4.2 sec after releasing.
Upon detonation it splits into fragments which then spread across an area about 30m in diameter. Those caught within 5m of the exploding grenade are nearly always killed.

M67 20 7
RGD-5 20 7
L109A1 20 7

In ArmA 2, hand grenades are used by all factions and are available in up to three variants. Damage-wise, all are the same and have identical blast radii of 7 metres.

BLUFOR factions such as the USMC and U.S. Army utilised the M67 frag grenade. British forces on the other hand carried the L109A2 HE grenade. Infantry for REDFOR factions like the Russian and Takistani militaries or NAPA/ChDKZ guerillas carried the RGD-5 HE grenade instead.

Grenades in ArmA 2 must be manually selected and primed like in Cold War Assault/Armed Assault. How far the grenade gets thrown will depend on how long the user holds the primary fire key. In addition, grenades no longer detonate upon impact with the terrain and have proper fuse timers of 4 seconds.

However, they also have a tendency to bounce beyond their intended target; particularly if thrown on flat and non-natural surfaces. Users should take care to avoid using too much "power" when throwing a grenade as a result.

ArmA 3

ArmA 3-era hand grenades

« Use grenades to quickly dispatch enemies behind cover. The angle of the throw has a great influence on its distance.
Field Manual
Grenade variant Base damage value Blast radius (metres)
RGO 8 6
RGN 6 4

ArmA 3's hand grenades are now reverted back to Cold War Assault standards and are universally employed by all factions regardless of their side. BLUFOR, REDFOR and INDFOR alike share the RGO HE grenades and RGN mini-frags.

The RGO is the standard-issue grenade carried by most line infantry. It cannot be thrown far but has a larger kill zone radius of 6 metres and deals more damage. The smaller RGN on the other hand deals less damage, has a smaller blast radius of only 4 metres, and is limited to use by recon and special forces only. However, it can be thrown much further and is more precise for long distance targets.

Unlike in previous games, grenades no longer need to be selected as a separate weapon nor do they need to be primed, but they can still be manually cycled through to switch between RGOs/RGNs. A consequence of this change is that the user can no longer adjust the "power" of their throw, which means that they are only able to change the direction in which the grenade gets thrown in.

ARMA Reforger

Reforger-era hand grenades

Field Manual

ARMA Reforger's hand grenades are side-specific once more and are no longer universally shared amongst BLUFOR and REDFOR factions. The U.S. military wields the M67 while Soviet forces and the FIA make use of the RGD-5.


  • The Cold War Assault hand grenade is based on the American-made "M26" and is oddly used by Soviet forces as well. This is completely unauthentic to real-life however as the Soviet military at the time utilised the "RGD-1" instead, not the M26 as depicted in-game.
  • For both Armed Assault and ArmA 2, the BLUFOR grenades are modelled on the real-world "M67" fragmentation grenade, while for REDFOR factions it is based on the Soviet-era "RGD-5" grenade.
    • However, the L109A1 grenades used by British forces are not actually modelled after the real-world L109A1 grenade and incorrectly reuse the M67's model instead.
    • Although the L109A1 in real-life does share some similarities with the M67, they are based on Swiss-made "HG 85" grenades which have a slightly different appearance and would not be exactly the same as the M67. Whether this was intended or was simply an oversight is not known.
    • RGD-5s in Armed Assault are incorrectly named as RGOs. Though it functions similarly to the real "RGO", its appearance is not based on the RGD-5 as shown in-game.
  • The ArmA 3 RGO is once again modelled on the "M67" while the RGN is based on the Dutch-made "V40 Mini-Grenade".
    • The names and models for the ArmA 3 hand grenades are completely incorrect. Just like in Armed Assault, the so-called "RGO" is actually a Soviet-era TNT-based grenade while the "RGN" likewise is a smaller counterpart to it
    • Its use by in-game Mediterranean and Pacific CSAT forces - which are based on the Iranian and Chinese militaries respectively, is also highly unrealistic. The armed forces of both nations have their own proprietary hand grenade designs (like the Chinese-made "Type 82" HE grenade).
    • Likewise, the V40 grenade has long since been retired from active service with Western militaries and would be anachronistic for the mid-2030s timeline that ArmA 3 is set in.
