Sexion d'Assaut, formerly known as 3ème Prototype, was a French hip hop band formed in 2002, composed of eight Parisian rappers. They are signed to independent record label Wati B, which is under exclusive license to Sony Music Entertainment France.
The founding members were L.I.O. Black M, Maska and Lefa. In 2003, it became a collective as Maître Gims and JR O Crom joined in. Throughout its existence, it included about 20 rappers, but set-up changed from time to time. The group distinguishes itself of staying away from "bling bling" that other French rappers have adopted.
