A barrier which is extensibly deployed from a vehicle and which includes at least three coils of barbed tape supported and spaced from one another with an upper coil located above two lower coils. The coils are spaced parallel from one another, and are supported, by transverse rods located along the respective lengths of the coils. Each coil is a plurality of short coils which are interconnected in axial alignment in head-to-tail relation, with adjacent short coils having oppositely directed senses of rotation to counterbalance any net rotational forces produced by each short coil.
