Helocasting and SPIE operations allow the recon Marines to enter and exit tactical landing zones that are inaccessible to helicopters during amphibious operations. The 31st MEU, the Marine Corps’ only continuously forward-deployed MEU, provides a flexible force ready to perform a wide-range of military operations in the Indo-Pacific region.
