GRISSOM AIR RESERVE BASE, Ind. -- As a general rule, for transporting an injured Airman on a litter, have one person give instructions so actions will be performed in unison. Here Master Sgt. Bradley Marcum, 434th Aerospace Medicine Squadron medical technician, gives a preparatory command to Master Sgt. Mike Dardini, 434th AMDS immunizations specialist, Staff. Sgt. Michael Allen, 434th AMDS health service apprentice, and Senior Airman Joseph Logan, 434th AMDS dental assistant. (U.S. Air Force photo/Senior Airman Carl Berry)
