The Special Forces Qualification Course (SFQC) or, informally, the Q Course is the initial formal training program for entry into the United States Army Special Forces. Phase I of the Q Course is Special Forces Assessment and Selection (SFAS). A candidate who is selected at the conclusion of SFAS will enable a candidate to continue to the next of the four phases. If a candidate successfully completes all phases they will graduate as a Special Forces qualified soldier and then, generally, be assigned to a 12-men Operational Detachment "A" (ODA), commonly known as an "A team." The length of the Q Course changes depending on the applicant's primary job field within Special Forces and their assigned foreign language capability but will usually last between 56 and 95 weeks.

The United States Army Special Forces (SF), colloquially known as the "Green Berets" due to their distinctive service headgear, is the special operations branch of the United States Army. Although technically an Army branch, the Special Forces operates similarly to a functional area (FA), in that individuals may not join its ranks until having served in another Army branch.
