Phrog SPIEs.

Reconnaissance Marines with Company C, 4th Reconnaissance Battalion, Marine Forces Reserve, conduct Special Patrol Insertion/Extraction, or SPIE rigging, out of a CH-46E Sea Knight helicopter with Marine Medium Helicopter Squadron 774, to maintain their qualifications during Integrated Training Exercise 4-14. SPIE rigging permits quick extraction of Marines from a situation where a helicopter cannot land or is limited on time. Reserve training exercises like ITX 4-14 are imperative to maintaining readiness and integrating seamlessly with their active duty counterparts.

Marine Medium Helicopter Squadron 364 (HMM-364) CH-46E Sea Knight helicopters combat swirling ash as they attempt to land on base in the aftermath of Mount Pinatubo’s eruption.  The volcano, which erupted for the first time in over 600 years, forced the U.S. military to coordinate Operation Fiery Vigil evacuation efforts to remove more than 20,000 evacuees from the area.
