As used by NATO Forces

  • "The possibility to issue the M32A1 and the to individual’s soldiers, as either a primary weapon or an alternative support weapon has accentuated the versatility of the weapon. This, combined with the range of ammunition allows for a crucial impact in the theater of operation."

    - Battalion Commander of Special Forces.

  • "The M32A1 and MGL-AV140 are equally suitable for application in the static guarding role such as guard posts, gate control posts, roadblocks, and mobile or foot patrols guarding bases or other facilities. A great advantage is the stopping power by means of the grenade explosion to actually stop or break the momentum of approaching vehicles, trucks, or light armoured carriers and small boats. "
