Graphic packs to make your regimental thread/website and it's users look fancy:
[*] Images for Ranks, rosters, badges, awards etc. (Includes PSD files to customize your own!) by Spunned
[*] Images for Ranks, detachments, badges, awards etc. (Includes PSD/Illustrator files to customize your own!) by Loppen
Tools
The packs above contain PSD files that you can edit in photoshop to customize it for your own regiment, not everyone has photoshop however. Luckily there are programs out there that are free and can open photoshop files aswell.
[*] Gimp Free image eidting software that can open & edit PSD files. (Cannot open Illustrator files)
If you know any good tool, graphical pack or perhaps something else that's free and can help Regiments/Armies in their looks or management, then post here on the topic and I will think about adding it to this list.
