Abstract: A T-shaped combined smoke-producing projectile and launch housing assembly aving dual-canister means for establishing an effective smoke screen simultaneously with an effective source of illumination and light-radiation throughout the duration of projectile flight after initiation of the launch or propelling charge. The aforesaid assembly is adapted to be attached to and detached from a tank or other vehicle within about 30 seconds via suitable quick release mounting means not comprising a part of this invention. The assembly includes a launching or propelling charge disposed within a propelling charge chamber, and means for causing simultaneous ignition of the compounds within the dual smoke generating canisters and of intense light-radiation to help blind enemy automatic weapons systems after the projectile has been launched.
