Do you know what they were used for or were they just for fun.
Ripcord's a combo Ranger, ESD (medical) and DPW pern. He makes up several style of patches throughout the year and ends up gifting them to pretty much everyone in a particular department which he's designed for. The scans really don't do these justice as the colors are much more vibrant when viewing the real thing.
He has them done somewhere in New York I believe. The company does a lot of military squadron, police and fire dept patches.
If you click on the thumbnails they give a much more detailed version. My fave is the very green patch for Perimeter. The various shades above the Man's head represent the sweep of a radar screen which we refer to as the Lighthouse. Lighthouse is a tracking unit that we utilize to see hippies 3-4 miles from the perimeter fence who're trying to sneak in.
Some refer to it as the Eye of Sauron.
