Terry Gilliam’s The Suicide squad (2006)

The modern incarnation of the Suicide Squad is Task Force X, an American special operations team composed mostly of incarcerated supervillains who undertake high-risk black ops secret missions in exchange for either parole, work release, and/or reduced prison sentences. Regardless of abilities and talent, every member of the squad is expendable and it is expected that not many will return. As expendable assets, all members are fitted with an explosive device in their neck to assure obedience.
