In addition to the CASEVAC set issued to USSOCOM, Tribalco has also introduced several new, smaller, specialized kits. One example of this is the Trunk Kit.
Designed specifically for LE first responders to render basic aid, the Trunk Kit was modified from a sub kit in the CASEVAC system. This bag configuration includes stopping bleeding, CPR and and prevent hypothermia. While the IFAK will support one person, the Trunk Kit supports up to six patients. The overall form factor will Velcro into place in a trunk, hence the name. It opens fully to expose all of the contents which can be customized based on local protocols.
Think of the IFAK as small, Trunk Kit as Medium and for a Large medical kit, Tribalco offers a Mass Casualty Kit.
