Ok, here is a wee lil Flag Patch. This is not a MOD release nor shoud it be countered as such. Its based off Serg's work and some1 else's that I can no longer remember who. It has included markings for AC to match if you want it. There is no readme as I dont consider this a mod. Just unzip and copy or cut and paste into your SilentHunter III Folder.

PS: The "Marking under the Union Jack" is the 7 Pointer Star of Federation of Australia. 1 Point for each State and Territory, bar 1, the ACT.
