Senior Airman Collin Kerrigan, a water fuels system maintenance specialist with the 155th Civil Engineering Squadron, stands at attention for a Class A dress blues inspection Jan. 7, 2018, at the 155th Air Refueling Wing, Nebraska National Guard air base, Lincoln, Nebraska. The CES conducts an inspection every year. "We just want to make sure everybody's uniforms are up-to-date and ready to go," said Senior Master Sgt. Sarah Bredthauer, the CE Operations Flight Superintendent. "You never know when you're going to wear your blues, and most of the time it's very unexpected."
