Staff sergeant (SSG) is E-6 rank in the U.S. Army, just above sergeant and below sergeant first class, and is a non-commissioned officer. Staff sergeants are generally placed in charge of squads, but can also act as platoon sergeants in the absence of a sergeant first class.
First Lieutenant is a military rank and, in some forces, an appointment. The rank of Lieutenant has different meanings in different military formations (see comparative military ranks), but the majority of cases it is common for it to be sub-divided into a senior (First Lieutenant) and junior (Second Lieutenant) rank. second lieutenant (grade O-1) is usually promoted to first lieutenant (grade O-2) after 18 months in the Army or 24 months in the Air Force and Marine Corps.
