The Angels Of Shadow Tactical Shouder Symbols Squad 1 are designed to work with most marine models. They are designed so you can easily use some glue and use putty/filler to add them to an existing shoulder pad, and then the raised symbol makes painting easy. They come in a set of 64 and are designed to easily snap off or using a set of clippers. Then prime them and glue them to your model. Any gaps due to differences in the shoulderpad and the symbol can be handled with putty/filler.
