1. An armored vehicle comprising a laterally alignable mortar operated by a firing crewman, the armored vehicle incorporating a turret for housing the firing crewman, said mortar incorporating a number of launching barrels which are rigidly connected with the laterally alignable turret of the armored vehicle, the launching barrels having muzzles which are located at the wall of the turret, an annular compartment concentrically arranged with respect to the axis of rotation of the turret arranged about the turret, an armored vehicle hood member for protecting the annular compartment, an infeed mechanism for the shells and magazines arranged in the annular compartment, said magazines being movable relative to the turret by means of said infeed mechanism into a position in alignment with the mortar, the turret possessing a substantially truncated conical configuration, and wherein the launching barrels are directed perpendicular to the wall of the turret, said infeed mechanism comprising to support for the shells, and said shells being arranged at the support perpendicular to the wall of the turret with their shell tips pointing towards the outside.

7. An armored vehicle comprising a laterally alignable mortar operated by a firing crewman, the armored vehicle incorporating a turret for housing the firing crewman, said mortar incorporating a number of launching barrels which are rigidly connected with the laterally alignable turret of the armored vehicle, the launching barrels having muzzles which are located at the wall of the turret, an annular compartment concentrically arranged with respect to the axis of rotation of the turret arranged about the turret, an armored vehicle hood member for protecting the annular compartment, an infeed mechanism for the shells and magazines arranged in the annular compartment, said magazines being movable relative to the turret by means of said infeed mechanism into a position in alignment with the mortar, means for infinitely varying the propellant charge chamber at the launching barrels for the purpose of altering the firing range of the shells, said means for varying the propellant charge chambers comprising a sleeve member displaceable within each lauching barrel and serving as a stop for the shells, said sleeve member being equipped with external teeth, and further including helical gears and a shaft, said sleeve member being in driving connection with the shaft via the external teeth and the helical Gears, said sleeve member possessing four forwardly extending arms which are uniformly divided about the periphery thereof, two of said arms being situated diagonally opposite one another and carrying said external teeth, and both of the other arms protruding somewhat past the arms equippped with the external teeth and having a point.

8. An armored vehicle comprising a laterally alignable mortar operated by a firing crewman, the armored vehicle incorporating a turret for housing the firing crewman, said mortar incorporating a number of launching barrels which are rigidly connected with the laterally alignable turret of the armored vehicle, the launching barrels having muzzles which are located at the wall of the turret, an annular compartment concentrically arranged with respect to the axis of rotation of the turret arranged about the turret, an armored vehicle hood member for protecting the annular compartment, an infeed mechanism for the shells and magazines arranged in the annular compartment, said magazines being movable relative to the turret by means of said infeed mechanism into a position in alignment with the mortar, means for infinitely varying the propellant charge chamber at the launching barrels for the purpose of altering the firing range of the shells, said means for varying the propellant charge chamber comprises a sleeve member displaceable within each launching barrel and serving as a stop for the shells, the sleeve member possessing internal threading, a threaded spindle, the internal threading of said sleeve member being in driving connection with the threaded spindle, an external sleeve, the sleeve member being displaceable within the external sleeve, said external sleeve being sealingly guided at the floor of the firing mechanism and together with the threaded spindle being mounted to be axially non-displaceable at a plate member, a further threaded spindle mounted at the firing mechanism, said plate member being displaceable at said further threaded spindle.

10. A mortar comprising a launching barrel having a lengthwise axis and equipped with a muzzle, means for the infeed of shells in front of the muzzle of the launching barrel, said infeed means incorporating a rotatable support, a plurality of shells arranged upon said rotatable support, the axes of said shells forming with one another an imaginary cone surface, the axis of the cone coinciding with the axis of rotation of the rotatable support and the axis of the launching barrel being located at said cone surface.
