first post in here and decided to show my face at this time (I'm the guy responsible for a lot of the schemes... they keep me in the paint shed to keep me from becoming a nuisance!) ....
it is indeed BLUFOR as i refer to it, the Scheme is loosely based upon the USAF's trial 'Ferris' camouflage, as to the roundel, I can take the blame for that design.... I used to run, a while back, an online virtual Private Military Contractor.... 'Mercenair' (Mercenaire being the French word for Mercenary, we dropped the 'e' to keep it Air based... there's method to my madness... sometimes) and being Greek by Birth but English by parentage i wanted a Roundel that was Unique.... so i went for the old Spartan 'Lambda', like you see on the shields... this signified that the line would be held for as long as we could at all costs no matter how few we were.... the Bars on the Roundel were due to the vPMC being US Based.... so now you know the back story to the roundel.... i felt it was time to release it to you guys, let you all run with it, and so it was applied to the -21.... if anyone does want the roundel in large size for their own scheming just let me know and i'll be more than happy to get that out to you all!
See you on the Flightline!
