In an embodiment, a hybrid slat armor configured for protecting a body against a threat having an anticipated impact direction. The hybrid slat armor comprises a plurality of slat units, each extending along a first longitudinal direction, the units being spaced apart along a second direction perpendicular to the first direction. Each slat unit has a strike end configured for facing the anticipated impact direction, a rear end opposite the strike end, a top set of piercing elements and a bottom set of piercing elements. The piercing elements of each set are successively arranged along the longitudinal direction of the slat unit at the strike end thereof and are spaced apart in the longitudinal direction; The piecing elements of the top set are spaced from the piercing elements of the bottom set in the second longitudinal direction to a distance which is considerably smaller than that between adjacent slat-units.
