This Hoplite was first delivered to the Czech Ministry of the Interior (FMV) in July 1990 and transferred over to the Czech police in January 1993. During this period the Czech Bovernment had noted the success of helicopters around Europe in helping the emergency services and so from 1st April 1987 the (Czech) Air Rescue Service (Záchranná služba - Air Ambulance) began operating. This helicopter is on display in the excellent Fire Protection Exhibition museum in recognition of this fact.
