Hundreds of prescription glasses sit ready and waiting for patients at a health services outreach site during Pacific Angel (PACANGEL) 17-2 in Tam Ky, Quang Nam Province, Vietnam, Sept. 11, 2017. Now entering its tenth year, PACANGEL ensures that the region’s militaries are prepared to work together to address humanitarian crises. Since 2007, PACANGEL engagements have impacted the lives of tens of thousands of people by providing health services ranging from dentistry, optometry, pediatrics and physical therapy to civil engineering programs, humanitarian aid and disaster relief and subject matter exchanges.
