The troops involved in the attack included the Military Police Fourth Battalion and, in particular, the Džokeri Unit. The Džokeri (Jokers), an anti-terrorist squad with twenty or so members, were created in January 1993 from within the Military Police on the order of Zvonko Voković, whose mission was to carry out special assignments such as sabotage, stationed at the bungalow in Nadioci. Other participants included the Vitezovi, the Viteška brigade of the municipality of Vitez, the Nikola Šubić Zrinski brigade of Busovača, together with Domobrani units (units set up in each village in accordance with a decision from Mostar dated 8 February 1993) stationed at Ahmići, Šantići, Pirići and Nadioci. Many witnesses in the Blaškić case also referred to soldiers in camouflage uniforms being present, wearing the emblem of the Croatian Army. Several Croat inhabitants of these villages also participated in the attack. They were members of the Domobrani such as Slavko Miličević for the Donji Ahmići sector, Žarko Papić for the Zume area, Branko Perković in Nadioci, Zoran Kupreškić in Grabovi (an area in the centre of Ahmići), Nenad Šantić and Colic in Šantići.
