An anti-ram vehicle barrier system adapted to arrest an impacting vehicle of substantial mass within a selected distance of the barrier. The barrier system includes a fence portion and/or a gate for selectively allowing passage through an entry port. The fence portion includes a pair of terminal posts positioned in and secured to the ground in a spaced apart relationship and cables connected between the terminal posts. The gate includes a cable extending across a panel that is connected on opposing ends to opposing posts positioned on opposite sides of the entry point. For passage the panel is moved relative to the posts and to the ground.
