Powder-fine sand clings to a Marine’s hand print on the back window of a Mine Resistant, Ambush Protected vehicle during a convoy conducted by Combat Logistics Regiment 2, Regional Command (Southwest), in Helmand province, Afghanistan, Sept. 29, 2013. Long military convoys kick up the sand, commonly referred to as “moon dust," and choke visibility on the province’s isolated desert roads.
