Seconded. There should be options for wire mesh, metal grating/rebar, and plating w/ vision slit. Mesh should be fairly ineffective and provide no wind protection but cause minimal loss of vision. Metal grating would be a reinforced version of mesh that reduces vision range. Vision slits would be strongest and provide a sealed environment, but would severely restrict field of view. Firing ports would be a variation on vision slits without any glass, allowing wind through while firing out.
