1. An armored cab having a longitudinal axis and a transverse axis, the armored cab comprising:
a right side frame extending parallel to the longitudinal axis;
a left side frame extending parallel to the longitudinal axis; and
a cab lower surface extending from the right side frame to the left side frame comprising:
a right hull transitioning at a right inflection point to define an integral right front plane defining a forward facing surface of the right side frame, wherein the right front plane is convexly curved upwards,
a left hull transitioning at a left inflection point to define an integral left front plane defining a forward facing surface of the left side frame, wherein the left front plane is convexly curved upwards, and
a center tunnel having a center tunnel right edge coupled to a first outer portion, the center tunnel having an exterior curvature with a variable radius extending upward along the transverse axis of the armored cab from the center tunnel right edge to a center tunnel upper boundary and downward from the center tunnel upper boundary to a center tunnel left edge coupled to a second outer portion, wherein the first outer portion and the second outer portion each have a convex exterior curvature along the transverse axis of the armored cab.
