Here's what I used in my Elestrial Concordat MGT game:

Left side is officers, right is enlisted
Top to bottom: Navy, Marine, Patrol, Scouts
Rank is shown for officers with cuff stripes and shoulder boards, for enlisted with sleeve chevrons and rockers.
Note: rank 0-1 scouts wear officer uniform without boards, Senior Scouts wear boards with Rank 1 stripe.
Officers and all scouts have narrow lapels, enlisted don't. Officers and senior scouts have shoulder boards, scouts don't..
