Hi Steve

Don't forget modern subdued can fall into the following:Woodland's BDU subdued, Woodlands BDU subdued Velcro (short lived 2003-2005),Desert subdued , Desert Velcro (2003-2005 short lived )ACU Grey green Velcro(2005-2015, Multicam/Scorpion Velcro (2010-onwards). Dates are approximate.

The early OIF/OEF had Velcro added at Central Issue Facility CIF) before full production swung into action.

Modern era also has variations in eyes , beaks etc....

The last one ACU Grey is a production run with velcro as part of the process, the others CIF.
