Locally manufactured grenade

Also known as
  • Locally fabricated grenade
  • Locally made grenade
  • Drone-carried locally fabricated grenade
  • Grenade-strapped drone payload

Locally manufactured grenade is the public-source wording for an improvised grenade payload carried by Boko Haram/ISWAP-linked armed drones during the 24 December 2024 Wajiroko attack in Borno State. Sources do not identify a factory model, fuze, casing, or exact explosive fill, so the entry covers the documented locally fabricated payload rather than a standardized grenade family.

Specifications

Identification
Described in reporting as locally manufactured or locally fabricated
Delivery
Carried by multiple armed drones in the 24 December 2024 Wajiroko attack
Reported quantity
Up to four armed drones were observed in the Wajiroko drone attack
Function
Improvised explosive payload used in a drone-delivered strike on a military position
Public detail
Exact model, fuze, casing, explosive fill, and dimensions were not identified in the public reporting
Identification Limits

The public record identifies the payload by descriptive manufacture terms rather than a model name. That makes the strongest supported reading a locally fabricated grenade adapted for drone carriage, not a named industrial grenade type.

Reported terms

Sources use locally made, locally manufactured, and locally fabricated grenade wording for the Wajiroko payload.

Carrier

The grenades were reported on multiple armed drones in the 24 December 2024 attack.

Unidentified details

Public reporting does not name a fuze, casing type, explosive fill, dimensions, or fabrication workshop.

Variants

Public reporting uses descriptive terms rather than a formal designation, so the variants below preserve the reported naming forms without implying a standardized model series.

  • Locally fabricated grenade
  • Locally made grenade
Carrier Drones

Reporting on the Wajiroko attack connects the grenade payload to commercially derived armed drones rather than a conventional hand-thrown employment method.

ISS, The Nation, Defense Mirror, and Peoples Gazette described armed drones carrying locally made, locally manufactured, or locally fabricated grenades in the 24 December 2024 Wajiroko attack.

Timeline

Locally manufactured grenade Key Events

  1. Wajiroko drone attack

    Reporting on a Nigerian military signal said militants attacked FOB Wajiroko after an initial mortar-and-firearms assault, using multiple armed drones carrying locally fabricated or locally manufactured grenades.

  2. Nigerian Air Force counter-UAV response

    Nigeria's Chief of Air Staff cited the Wajiroko incident while describing an integrated counter-UAV response to terrorist drones carrying locally fabricated grenades.

  3. ISS Lake Chad assessment

    Institute for Security Studies assessed the Wajiroko attack as a turning point in Lake Chad Basin insurgent drone use and described four ISWAP armed drones carrying locally made grenades.

In the Lake Chad basin, reporting links ISWAP and Boko Haram-linked forces to a late-2024 shift from ISR and propaganda drone use toward armed quadcopter attacks carrying locally made or locally fabricated grenades against Nigerian military positions in Borno and Yobe.
Craft-produced firearm, Locally fabricated small arm, Infantry WeaponsInfantry WeaponsCraft-produced firearmLocally fabricated small armCraft-produced firearms in Nigeria are locally fabricated small arms made outside formal industrial production, ranging from muzzle-loading Dane guns and break-action shotguns to self-loading pistols, sub-machine guns, and AK- or G3-style rifle copies. Small Arms Survey documented craft-produced weapons in a Boko Haram cache captured in 2018, and UNIDIR reports their wider use by community-security actors in northeast Nigeria during the 2009 Boko Haram Insurgency.

Public reporting documents pickup-mounted rebel launchers in the 2011 First Libyan Civil War and a four-tube ISWAP/Boko Haram-side pickup launcher in the 2009 Boko Haram Insurgency, giving irregular forces a mobile but inaccurate area-fire capability from standoff range.

Technical references disagree on the explosive fill, while conflict reporting documents the type in Iraq weapons caches, Boko Haram-captured materiel in northeast Nigeria, and opposition-area Syrian arms-market listings.
