The U.S. Army has issued a new manual (large pdf) on unmanned aerial systems (UAS), which are increasingly used in a wide spectrum of reconnaissance, surveillance and targeting missions.
UAS include what were formerly referred to as unmanned aerial vehicles (UAVs), plus their payloads and support systems.
The new Army manual includes fresh information on Army UAS programs and operations.
A copy of the unclassified manual was obtained by Secrecy News.
