A system for providing a vehicle with landmine protection for occupants of a vehicle cab via controlled articulation of the vehicle cab in response to an under-vehicle explosive event includes a cab guide pin attached to the rear of the vehicle cab, and a vehicle frame having a sub-frame. The vehicle cab is mounted on the vehicle frame. The sub-frame includes a sub-assembly slot and the cab guide pin is disposed laterally at a first end in the sub-assembly slot. The sub-assembly slot has a substantially straight first section that is longitudinally positioned and having the first end of the sub-assembly slot, and a second arcuate section that extends vertically and forward from the first section opposite of the first end of the sub-assembly slot. When the vehicle is exposed to an under-vehicle explosive event, the vehicle cab articulates such that the cab guide pin travels forward through the first substantially straight section of the sub-assembly slot and in an arcuate path through the second arcuate section of the sub-assembly slot.
