what is a Delta force
The Delta Force (1st Special Forces Operational Detachment-Delta), is a U.S. Army unit used for hostage rescue and counterterrorism, as well as direct action and reconnaissance against high value targets.elta Force was formed after numerous, well-publicized terrorist incidents in the 1970s. These incidents led the U.S. government to develop a full-time counter-terrorism unit. Key military and government figures had already been briefed on a model for this type of unit in the early 1960s.
