This mod adds historical ERDL camo pattern to the BoS Field Scribe outfits, such as Field Scribe's armor (the one with the backpack) and Brotherhood Fatigues. It includes both the stock version (the one with the red sweater in the vanilla version), as well as custom variants with white, brown and black sweater.

Camo Scribe hat is also included :)

ERDL pattern was developed US Army at its Engineer Research & Development Laboratories (Hence the name :) ) in 1948, although it was not issued to the soldiers until early 1967. It was later used as a basis for M81 camo pattern, reflecting a shift in the tactical focus of the US military from an extremely close-range war in Vietnam to a longer-range battlespace on the fields of Europe.
