“They lost everything”: what its like to deploy to disaster-stricken communities
In the aftermath of Hurricane Maria, a Puerto Rico community celebrated Christmas by using birdhouses to build a nativity scene. Several of the birdhouses’ roofs are painted blue to symbolize the corps’ Blue Roof mission. Operation Blue Roof provides homeowners in disaster areas with temporary roofing, made of fiber-reinforced sheeting, that protects damaged roofs until permanent repairs can be made (U.S. Army photo by James Frost).
