An energy dissipation assembly is provided for mounting between a fixed support and moveable support. The assembly includes a sacrificial deformation tube, a hardened cutter/deflector assembly and, optionally, a connecting cable to maintain the cutter/deflector assembly in juxtaposed coaxial alignment with an end deformation tube. The cutter/deflector assembly has a generally flattened disc shaped profile and including a central hub, a circular support ring and one or more cutting blades. The support ring concentrically about the hub and has an inner diameter greater than the outer tube diameter. On the occurrence of a shock force, the cutter/deflector assembly moves axially to cut/deform the deformation tube to dissipate force energy.
