Master Sgt. Michael Riggenbach, occupational safety technician assigned to the 910th Airlift Wing, operates a Spangdahlem Air Base "Skid Monster" July 10, 2018, on SAB, Germany. While at SAB Riggenbach assisted with vehicle safety classes, part of the class was operating a vehicle meant to mimic a car skidding on ice. All Airmen 26 years old or under are required to take the vehicle safety class and "Skid Monster" operation course when stationed on SAB. The 910th AW Reserve Citizen Airmen on annual tour in Germany trained with their active duty counterparts and filled critical shortages for the active duty during their peak leave period.
