Oregon Army National Guard Spc. Stefanie Blanchard, of the 224th Engineer Company, demonstrates search and extraction marking techniques to a group of Vietnamese engineers with the 249th Engineer Brigade, Vietnam People’s Army, Sept. 23, at the 249th Engineer Brigade Headquarters in Vietnam, during a week-long search and rescue technique exchange as part of the Oregon National Guard's State Partnership Program. The markings are used to identify different areas in a disaster zone or collapsed building and provide information such as casualties in the rubble, search teams in the rubble, or fatalities. The Oregon National Guard formally began its partnership with Vietnam's National Committee for Search and Rescue (VINASARCOM) in November of 2012. The partnership is designed to enhance the capabilities of VINASARCOM and the Oregon National Guard in areas of light and medium urban search and extraction and medical first response in disaster situations.
