Over the years I've been playing airsoft, I've amassed a fair number of patches and the like.
Among the ones I like the most are the patches given at Ops.
Operation Crimson Dunes - August 16-18, 2002 (Agua Dulce, CA)
Operation Restore Order - November 7-9, 2003 (Riverside, CA)
Operation Lion Claws III - May 28-30, 2004 (Tehachapi, CA)
Operation Cold Burn - November 19-21, 2004 (Four Peaks, AZ)
Operation Lion Claws IV - May 27-29, 2005 (Tehachapi, CA)
Operation Irene III - September 23-25, 2005 (Ft. Knox, KY)
Operation Lion Claws V - May 26-28, 2006 (Hesperia, CA)
I don't know what that is on the Crimson Dunes patch. It kinda looks like a scorpion, but it only has six legs, so who knows.
But I think these are my favorite.
At some point in the future, there will another run or perhaps another version of the AA patch for those people who don't have these ones.
