What casualty movement device is typically lowered from a hoist during MEDEVAC operations?

In MEDEVAC operations, the sked is a specialized device designed for transporting casualties in various environments, particularly when conditions are challenging or when a patient has injuries that require immobilization. The sked is beneficial because it can be easily lowered from a hoist due to its lightweight and compact design when rolled up.

This versatility makes the sked an ideal choice for aerial extrications, where space constraints and the need to secure a patient quickly are critical. Unlike other devices, the sked can be used in both flat and rugged terrain and can be adapted to fit a wide range of patient conditions, making it particularly useful in emergency medical situations. Additionally, the sked can be deployed rapidly from a hoist without the need for extensive preparations, enhancing the efficiency of the MEDEVAC process.
