July 2018 USACE DoD Anti-Ram Vehicle Barriers List Update

The DOD Anti-Ram Vehicle Barriers: July 2018 document adds several new barriers and adds two new aspects of defensive geometry.

  • “interpolated” designs where a barrier is tested for openings of 10′ and 20′ and is also approved for in between distances. such as 13′.
  • designs where a barrier is only able to be used for a particular engineered distance such as 20′.  This is challenging if your site doesn’t work in neat 10′ or 20′ increments.

To create this standard, the DoD employs an ASTM International performance standard and testing procedure for both active entrance barriers and passive perimeter barriers designated as “vehicle-impact rated barriers,” or “anti-ram barriers.” The current standard is ASTM F2656-07, Standard Test Method for Vehicle Crash Testing of Perimeter Barriers.

The ASTM F2656-07 test standard rates barriers in twelve impact categories, with three predetermined impact velocities for each category and four potential penetration ratings for each impact rating. These penetration ratings are: P1 – < 3.3 ft; P2 – 3.31 to 23.0 ft; P3 – 23.1 to 98.4 ft; and P4 – > 98 ft.

A few characteristics to consider are listed below (list taken from the DoD’s Protective Design Center – unlimited distribution):

  • Impact speed at barrier (low speed impact): The use of some vehicle barriers
    presented in this list exhibit vulnerabilities when impacted at speeds other than
    those associated with the ASTM and DOS test impact velocities.
  • Design Basis Threat (DBT) vehicle, other vehicle weights and speeds: The barriers
    presented in this list have been subjected to impacts under the specific conditions
    prescribed by the test designation. If the Installation’s DBT includes vehicles
    significantly different than the test vehicle, performance of the system may differ
    from what may be expected.
  • Deployment mechanisms: The mechanisms used to deploy vehicle barriers vary
    (pneumatic, hydraulic, electro-mechanical, manual). The various mechanisms
    should be investigated and the choice should be based on the best fit for the
  • Environmental condition at barrier: Environmental conditions can vary greatly
    from location to location. Conditions such as rain, snow, ice, sand, gravel, hot, and
    cold need to be considered when selecting a barrier for a specific location.
  • Operations and Maintenance (O&M) requirements: Each barrier comes with its
    own operational and maintenance requirements. The O&M requirements vary in
    the amount and intensity from barrier to barrier. O&M needs to be figured into the
    overall life cycle cost of the barrier.
  • After impact barrier gaps: Post impact gaps may be an inherent characteristic of the
    barrier system. The barrier system’s post-impact condition should be carefully
    evaluated for its cap

Sloan Assists BSU/Special Forces Collaboration

Mark Johnson, KTVB 10:52 PM. MST February 19, 2017 – Special forces in the U.S. military are in need of a tool – One that can help them detect how many people are inside a building before they enter. If the development of this innovative technology is successful, it could save lives and help the military better fight the war on terror.

Building that tool is now in the works by a team of five graduate students at Boise State University’s Venture College.

“How do you protect the good guys and get rid of the bad guys?” asked Venture College Director Ed Zimmer.

That’s where the Boise State’s best and brightest come in.

They are a group of five select graduate students with backgrounds in computer science, design, and math, who are tasked with coming up with a high-tech device that could be worn on body armor or drone-deployed that would give teams in combat situations the ability to know who and what’s inside a building.

“This is an attempt to save human life,”  Said Marine Lt. Col. (ret.) Brian Von Herbulis.

Boise State is one of six universities around the country given a military technology problem to solve by the Department of Defense.

Students found out about the project – called Hacking for Defense – last October and are working to complete it by the end of the spring semester.

The speed at which they’re moving is one of the reasons Congress approved funding, knowing that it could take years for the infamously slow-moving Pentagon to complete the project. By that time, the technology would be obsolete, said combat veteran Von Herbulis, who was a deployed to the Middle East on three separate occasions.

Von Herbulis, like Boise security expert Brice Sloan, is volunteering his time as a mentor and consultant for the team, giving them guidance that only someone who has been in actual special ops missions can.

“You can’t put a price on something like that and it really makes a difference,” team member Ben Rozeboom said of their experienced mentors.

Zimmer, a former CEO at a Boise design/manufacturing firm, is leading the program for Boise State that will earn the students three credit hours.  The class credit means very little to Boise’s Corey Hennen, who says the project is about making a difference for soldiers in the theater of war.

“It means a ton,” Hennen said. “We really are trying to save lives, reduce casualties in drone strikes, raids, all the above. I lost a personal family friend, a detective, in a raid, and yeah, those things hit home. Being able to help people, that’s what we’re doing.”
