a wheel arm pivotably coupled to a chassis of the howitzer, the wheel arm comprising:
a chassis coupling feature centered on an arm pivoting axis;
a wheel coupling feature centered on a wheel rotation axis, and wherein the chassis coupling feature is spaced apart from the wheel coupling feature; and
a lever which extends from the wheel arm to a handle region at a free end, the lever having a lever engagement feature provided as a protrusion which extends away from the wheel arm along an engagement feature axis, the protrusion comprising a wall defining a cavity with an opening centered on the engagement feature axis, and the wall defines a drain aperture extending through the wall;
wherein the lever, the wheel coupling feature, and the chassis coupling feature are provided in series along the length of the wheel arm;, the method comprising:
a user grasping the handle region of the lever and applying a force to the lever so that the wheel arm pivots relative to the chassis about the arm pivoting axis.
