Testing. This barrier has not been crash-tested.
Passive Barrier Systems. The following is a compilation of passive vehicle barrier
systems used at DOD facilities. Included are generic systems that can be constructed with self-
help projects, using standard, locally available materials. Some of the systems have not been
formally tested, but should inflict substantial damage on a vehicle if impacted. Cost data for
passive barrier systems is provided in Appendix C. A consolidated list of passive barriers,
kinetic energy, and penetration data is provided in Appendix E.
