Only the CO of a squad can upload a squad insignia / patch and change it/update it
The CO can either upload a new updated file or if the squadron has been disbanded and no longer exists, then send Skuzzy a PM and ask if he can flush the squads subfolder....similar to how HTC flushes the unused gameid's
Like one of my old shade gameid's was Viper, about 4 to 5 months of Viper id being dormant (not used online or tied to a paid account) it was flushed, so it was available for anyone to use, in which someone did snatch it as soon as they found out it was available
Hope this helps
