This is for ribbon placement, order of how the ribbons should be and what doing an event more than once will equal.
Ribbons are a big deal for a uniform, and perhaps the most tricky to place. The only actual rule is that they need to be 1/8 inches from the top of the pocket on the left side. Other than that, you can have them all really close together or with 1/8 inches gap between the rows. I would recommend getting a ribbon rack (perfectly spaced bars to hold ribbons instead of the single brass bars that hold 3 that you can retrieve in your supply room). This holds them perfectly for me (of course, I have 19, so its incredibly hard to make them look decent without it). The order is on the charts above, which shows how the ribbons should look. This gives you an advantage for having all your ribbons in order and making sure you have them on correctly.
"Lamps". Lamps are the second thing over on the lower half of the page in the example. These are to be placed in the center of a ribbon if you have completed this more than once. Example, the Personal Appearence ribbon, which is awarded for outstanding uniform inspection grades, will be given once a year. If you continue to set this example, you will get a bronze lamp your second year of completion. Third year is replaced by a silver lamp, and fourth year is replaced with a gold lamp.
