Anti-ram systems according to embodiments of the invention comprise at least one bollard section comprising a base of limited height and a plurality of spaced bollards extending upwardly from the base. An anti-ram system according to embodiments of the invention may be erected or installed on a paved surface such as asphalt, concrete, paver stones, etc., or on an unpaved surface such as soil, and need not be partially of fully buried, and yet can qualify for Department of State crash ratings previously assigned to buried bollard systems. Disclosed anti-ram system also comprise a plurality of bollard sections and one or more connectors for interconnecting two or more of the bollard sections, and may also include an anchor or anchor system engaging at least each end of a bollard section not connected to another bollard section. The bollard sections may be filled with ballast and high friction structure may be attached to the bottom of the bollard sections to resist sliding after impact.
