Thanks guys, appreciate it. I'll try to work on the Royal Navy's (and the British Armed Forces and the US') but I'm pretty much still locked on this little project of mine.
Yes, actually I'm on the process of drawing the insignia for the Philippine Army, Air Force, Marine Corps and Coast Guard. And probably some for police forces and fire services.
I'm still kinda stuck though on the design for the metal collar insignia for the Warrant Officers. And the digital pattern for the camouflage pattern. (part of the AU timeline/storyline)
