Maj. Kevin Eilers (right), bio-environmental engineer for the Kentucky Air National Guard’s 123rd Contingency Response Group, demonstrates how to use a wet bulb globe temperature apparatus to Master Sgt. Peter Vicini during Operation Lone Oak at Volk Field, Wis., June 9, 2021. The apparatus takes temperature readings to determine work-rest cycles during certain weather conditions, which became crucial for safety during an unprecedented heat wave over the course of the exercise.
