Around the late 1960s Guardia units began to receive surplus American Olive Green tropical uniforms, the US Army OG-107 cotton sateen utilities and the M1967 Jungle Utility Uniform. Elite formations within the GN received camouflage versions of these same uniforms, first in the "Duck Hunter" pattern, soon followed by "Tigerstripe" ("ERDL Thai Tadpole type") and "Highland" ("ERDL 1948 Leaf pattern", a.k.a. "Woodland pattern"). National Police BECAT teams had their own distinctive "Tan leaf" pattern, which consisted of puzzle leaf-shapes in medium brown, light brown, and sandy-grey on a tan background.
