The Costa Rican National Guard was a military force that was sent to rescue the survivors of the Isla Nublar Incident in 1989. They had initially been very cautious about the situation, making calls back and forth between San José and Washington before help was finally sent. After rescuing the survivors via heavy duty helicopters, the National Guard then proceeded to destroy the facility on Isla Nublar through napalm bombing; killing all the dinosaurs on the island due to the immense danger the island posed.
