I would just wear the medals, but then people wonder what they are for or from what service. So, a collar devise and small SCW device usually gives them some indication that they are not Boy Scout or NSCC awards. Also, on my jacket at work, we are allowed two "pins" and it has been a thorn in my side, but I wear a full size SCW device and CPO cap device. Hey, I only have two pins on my lapel for work. Talk with other vets so it makes for a good rapport with people coming in.
