Inghimasi
Inghimasi (, "become immersed"), also called shahid (, "martyr") and istishhadi (, "martyrdom seeker"), are forlorn hope or suicide attack shock troops utilized by several Sunni jihadist groups, such as the Islamic State of Iraq and the Levant (ISIL), al-Qaeda, Jabhat al-Nusra, Tahrir al-Sham, Boko Haram, and al-Shabaab. Definition and etymology Inghimasi are usually well-trained guerrilla fighters who are organized into teams, and infiltrate enemy positions in order to cause as much damage as possible, generally expecting to be killed while doing so. They often wear explosive belts that are to be detonated when the possibility arises that they could be captured, run out of ammunition, or expect to be overwhelmed. Inghimasi fighters usually wear clothing resembling that of the target's forces, and use light weapons. Inghimasi have to agree to a 'no return' policy, and expect to die in combat. Unlike normal suicide attack forces, however, an Inghimasi can survive their missions and return to their base. The Islamic State gives new recruits the option of becoming an Inghimasi when enlisting, along with the option of operating a SVBIED or being a regular fighter. The word comes from the Arabic word Inghamasa (انغمس) meaning "to plunge" or "become immersed".
