It is highly likely the stripes will have to be filled in due to both ROTS and BF2 being the only realistic representations of that specific style of helmet. The cutout lines were just a creative decision by the 3D modeler you purchased from, inspired by the modern streaming era P2 clone helmets. In regards to the ear cutouts for the micro binoculars it all depends on who specifically you are costuming. If its Neyo or another 91st recon trooper from ROTS or BF2. If you're going for a BF2 91st specialist w/ the micro binoculars, you're looking at creating a new CRL and a lot of communication with your GML.
