Missing

The search is on for two missing Navy service members in Afghanistan, who are believed to be in enemy hands. From the Associated Press:

KABUL, Afghanistan – Two U.S. Navy service members disappeared in a dangerous area of eastern Afghanistan, prompting a massive air and ground search and appeals on local radio stations for their safe return, NATO and Afghan officials said Saturday.

The two left their compound in the Afghan capital, Kabul, in a vehicle Friday afternoon, but never returned, NATO said in a statement. Vehicles and helicopters were dispatched to search for the two, who may have been killed or captured by the Taliban in Charkh district of southern Logar province — about a two-hour drive south of Kabul, said district chief Samer Gul.

While extremely rare, it still surprises me that these things happen to our military. Given the edge we have regarding communication technology, and the military's rapid response to any battle and flare-up, how does this happen?
