The present invention concerns a ballistic protection against objects such as projectiles from fire arms, alternatively scatter from for example hand grenades. The protection comprises an enclosure (1, 2, 4, 5, 6, 7, 9) adapted so that the object (10) can penetrate the enclosure (1, 2, 4, 5, 6, 7, 9) in at least one area (2); at least one intermediate layer (3) comprising granules (27) arranged within the enclosure (1, 2, 4, 5, 6, 7, 9), which intermediate layer (3) and enclosure (1, 2, 4, 5, 6, 7, 9) are arranged to decelerate said object (10). The invention is further characterized in that: the granules (27) are movable arranged with respect to each other; the space in the intermediate layer (3) that is not occupied by granules (27) is filled by a gas medium to enable contact between adjacent granules (27); the granules (27) have mechanical properties so that a granule (27) is crushed and spread in the intermediate layer (3) when it is hit by an object (10), at the same time as adjacent granules (27) are subjected to impulses with a subsequent energy dissipation so that the object and fragments thereof remains in the protection with a reduced risk for ricochets.
