U.S. MC-140 Helicopter Support Team Helmet

Designed for the USMC by Gentex Corporation. This one was worn by a member of the Helicopter Support Teams. A helicopter support team (HST) is a unit of organization within the United States Marine Corps that manages the activities of a helicopter landing zone (LZ). It consists of a team of eight Landing Support Marines who are trained to hook up external loads to the hooks of primarily military helicopters.

This is a very rare helmet that is rarely offered for sale.
