Vertical lizard patterns in different colorways were apparently developed in Portugal from the original French horizontal patterns. The lizard pattern had been in use in Portugal since 1956 with the Air Force's Paratroopers, being extended to the Army's Special Rifles units in 1960. With the Portuguese Military engaged in the Overseas Wars mainly fought in the African jungles, the camouflaged uniform was issued throughout the whole Army and some units of the Navy and Air Force. In 1963, a vertical lizard pattern was developed, this replacing the French horizontal pattern. Paradoxically, the Portuguese vertical lizard pattern become popular amongst some of the guerrillas that opposed Portugal in the Overseas Wars and was later adopted by the armed forces of some of the former Portuguese African colonies after their independence.
