The Sinchis, also known as the Sinchis de Mazamari after their training location, are a paratrooping unit of the National Police of Peru specialized in counterinsurgency and anti-narcotics operations.

A paratrooper is a military parachutist—someone trained to parachute into a military operation, and usually functioning as part of airborne forces. Military parachutists (troops) and parachutes were first used on a large scale during World War II for troop distribution and transportation. Paratroopers are often used in surprise attacks, to seize strategic objectives such as airfields or bridges.
