It is unclear who developed the first tigerstripe pattern, consisting of sixty-four (64) stripes. The French used a similar pattern (Lizard) in their war in Vietnam. After the French left Vietnam, the Republic of Vietnam Marine Division continued using the pattern, a variant of which was later adopted by Vietnamese Rangers (Biệt Động Quân) and Special Forces (Lực Lượng Đặc Biệt). When the United States began sending advisors to South Vietnam, USMAAG advisors attached to the ARVN were authorized to wear their Vietnamese unit's combat uniform with US insignia. Soon, many American special operations forces in the Vietnamese theater of operations wore the pattern, despite not always being attached to ARVN units: it became the visible trademark of Marine Corps Recon, Green Berets, LRRPs, SEALs, and other elite forces.
