BALAD AIR BASE, Iraq -- Airman 1st Class Nathan Milliman, 332nd Expeditionary Civil Engineer Squadron emergency manager, helps Senior Airman Krista McVicar, 332 ECES emergency manager, put on a protection suit before responding to a simulated mysterious substance report during a battle drill here, March 26. The suits can be worn for up to an hour; Airmen must work diligently to ensure they don't become exhausted or too warm wearing the suits. The suits provide emergency managers with protection from chemical, biological, radiological or nuclear substances. Airman McVicar is deployed from Davis-Monthan Air Force Base, Ariz.
