I've been wanting to make some of these for a while now, as all the ones online are kinda garbage IMO. So I took a GRFS image, edited it to remove the crosscom, made a vector image from that, digitized it, then sent off the digitized file to get embroidered into actual patches. They're velcro backed and awesome.
From the trailer we see that they aren't wearing the patches on their shoulders anymore. Mostly because they're wearing normal civilian clothing under their gear. The patches they're wearing are attached to their backpacks/vests in most scenes.
