Although it remains flexible to its mission, Delta Force is known as a tier-one counter-terrorist unit in the US Army that has been responsible for killing or capturing high-value units. They are specifically directed to dismantle terrorist cells as well. Given how sophisticated the team is, joining is not an easy task. Some of the requirements needed to get in include attending Infantry One Station Unit Training (OSUT), within the rank of E4-E8, having at least four years in service and two and a half years of service left on enlistment, and so much more.
