The E2O staff will be wearing the Energy and Environmental Officer insignia on their uniforms beginning this week. This is the first insignia change for the Corps of Cadets in decades. Class of 2013 Cadet John Hurdt, Company I-4, holds out a deck of the playing cards recently. The cards feature slogans developed last year by cadets that focus on the importance of recycling. During a recent E2O meeting, Maj. Andrew Pfluger, Department of Geography and Environmental Engineering, presents the insignia cadets on the Energy and Environmental staff will be wearing on their uniforms for the first time this week.
