A multi-sectional, modular energy absorber 10 comprising one or more modules, which have one or more energy absorbing units 12 . Some have a first section 14 and a second section 16 that are united like a clamshell to form the energy absorbing unit 12 . There is a means for locating the sections 18 in relation to each other. First and second flange sections 20,22 extend from at least some of the first and second sections. There are means for coordinating energy absorbing units 24 in one of the one or more modules, the means for coordinating 24 having a topography including a number (n) of apertures 26 defined therein, where n is an integer >=0. At least some of the sections include an upper perimeter 28 , a lower perimeter 30 and an intermediate wall 32 extending therebetween with a number (m) of breaches defined in the intermediate wall before impact, where m is an integer >=0.
