The protection zone 30 is expandable by means of said movably arranged wall configuration 20 to an increased protection zone 30' in which the wall configuration 20 is arranged in the expanded position. The protection zone 30, 30' is configured to constitute protection for personnel and/or other protection worthy components and subsystems.

[0030] The vehicle body 10 further has a body portion 12 forming a volume. Said body portion 12 according to a variant has a basic protection level, the body portion 12 according to a variant being provided with armour constituting protection for basic armour level.

[0031] The wall configuration 20 comprises a movable wall element 40. Said wall element 40 is intended to be arranged in the vehicle body 10 and arranged to run essentially transversal to the longitudinal direction of the vehicle and run essentially from floor to roof in the vehicle so as to divide a space in the vehicle.

[0032] The wall element 40 is movable in the vehicle body 10 in the longitudinal direction for change of the configuration of said protection zone.

[0033] The wall element 40 has an inner side 40a with a surface intended to face the protected volume and an outer side 40b with a surface intended to be turned away from the protected volume. The wall element 40 has a roof side 40c arranged to run in connection to an upper area of the vehicle body 10 essentially transversal to the longitudinal direction of the vehicle, a bottom side 40d arranged to run in connection to a lower area of the vehicle body 10 essentially transversal to the longitudinal direction of the vehicle and sides 40e, 40f running along the respective vehicle side between said underside and upper side.

[0034] Said wall element 40 is intended to be arranged in the vehicle body 10, wherein the wall element 40 is movable between an expanded position shown in FIG. 2a in which said extended protection zone 30' is obtained, and a compressed position shown in FIG. 2b in which the wall element 40 is moved from the expanded position in the direction of the arrow A such that a compressed protection zone 30 is obtained.

[0035] Said wall configuration 20 further comprises removable additional protection elements 22, 24, 26, 28. Said additional protection elements comprise side protection elements 22, 24, roof protection elements 26 and/or bottom protection elements 28.
