The experimental DGIII pattern was the predecessor to the AOR2 pattern currently (2020) standard issue to the US Navy as seen on the NWU Type 3.
“Item: Custom” and “Material: Custom” on tags.
Torso fabric is thicker than Multicam G2 AC shirt.
Rubbery (silicone?) tag on arm pocket is characteristic of older Crye items before they switched to the ribbon some time after 2006 (as seen on LV MBAV).
“Experimental Prototype” on tag.
Field Pants (AOR1)
These were found together with the prototype shirts shown above. The pattern is known as “DGII”, and later “AOR1”. This pattern would also become more commonly used by the Navy by both Special Forces as well as regular personnel in desert areas.
Tag says “Army Custom”.
Later DGIII Field Shirt:
In later versions of DGIII, the pattern is now vertically oriented so it is more similar to the standard issue NWU III.
Despite its resemblance to the Navy’s uniform, it still says “Army Custom” on the tag.
There are small “DGIII” watermarks throughout the pattern.
DGIII Pattern Comparisons:
The prototype pattern is similar to later NWU Type 3 (AOR2) but horizontal and more subdued, especially the black portion which appears almost translucent.
The later DGIII pattern’s black is darker than the prototype.
The black on the later DGIII also appears to be “shinier” than the NWU III’s black.
Used by Delta Force (CAG) in 2006. The photos below are mostly from Iraq (except for the Chevrolet ad, obviously).
