Abstract: "A vehicle and the ballistic shock isolator therefor including a turret, a sensor assembly and a shock isolator isolating the turret from the sensor switch and including upper and lower annular members, a plurality of leaves secured at opposing ends thereof to the annular members, each of the leaves having a corrugated bellows shaped portion in the form of an even number of similarly shaped portions, alternate ones of the similarly shaped portions having an open end in opposing directions, each of the leaves varying in thickness and width in a direction from the upper annular member to the lower annular member. The variation in width of the portion is alternately from wide to narrow and then from narrow to wide in a direction from the upper annular member to the lower annular member.
