Some enlisted paygrades have two ranks. The Army, for example, has the ranks of corporal and specialist at the paygrade of E-4. A corporal is expected to fill a leadership role and has a higher rank than a specialist, even though both receive E-4 pay.
A specialist E-4 is one of the most common ranks held in the U.S. Army and is the highest rank for junior enlisted recruits. The following are U.S. Army personnel who may be qualified to receive the E-4 rank: Those who have passed the Basic Leader Course. Individuals who have been given lower-level supervisory duties.
Like nearly all the other branches of the Armed Forces, the United States Army consider all ranks E-4 and above to be NCOs. Corporals (E-4) are referred to as junior NCOs, however, they are given the same respect as any other NCO.
E-4 is the highest among the enlisted rank that you may enter the US Army and Basic Training. Enlisted Ranks E-5 and above are referred to as NCOs, short for non-commissioned officers. Corporals are also considered to be non-commisioned officers, and serve as the base of the non-commissioned Officer (NCO) ranks.
No, it's considered fraternization and not allowed. Why? Because the E5 is likely to be in charge of the E4.
Staff sergeant (SSG) is the E-6 rank in the United States Army, just above sergeant and below sergeant first class, and is a non-commissioned officer.
E-4 through E-6 are called petty officers. All E-7s are called chief petty officer, E-8s senior chief petty officer, and E-9s master chief petty officer. Rates are displayed on a rating badge, which is a combination of rate and rating.
Also, if you have enough college credits, you are eligible to enter Army basic training as an E-4 (Specialist). An E-4 Specialist is the highest Army rank that you may obtain when enlisting in the US Army as an enlisted soldier.
You become eligible for promotion to E-4, whether corporal or specialist, when you have spent a full 24 months in the service, and have been a PFC for at least six months.
E-4 is the 4th enlisted paygrade in the United States military, with monthly basic pay ranging from $2,503.50 for an entry-level E-4 to $3,039.30 per month for E-4 personnel with over 40 years of experience.
What Is the Highest Military Rank? The highest military rank is O-10, or "five-star general." It is symbolized by five stars for each of the military services. Although it is currently a part of the military service rank system, only nine Americans ever have held this rank.
E-7. Army. Sergeant First Class (SFC)
Master sergeant (MSG) is the eighth enlisted grade (E-8), ranking above sergeant first class and below sergeant major, command sergeant major, Sergeant Major of the Army, and equal in grade but not authority to a first sergeant.
Through out the film Lt. Dan refers to Forrest as Private Gump, despite him achieving the rank of Sergeant at the time of his discharge (signified by the patch on his sleeve).
Army Drill Sergeants ranks can be as low as E-4 (Acting Jack/ 3 stripe Sgt) and as high as E-7 Sergeant First Class (SFC).
The top police ranking is colonel. Below colonel is the rank of lieutenant colonel, then major, captain, lieutenant, sergeant, trooper first class, and trooper.
Promotable Soldiers in the grade of E-4 will be allowed to stay up to 12 years.
Military Marriage Rules
A set of rules also govern "military fraternization." Among other prohibitions, those rules generally say that an enlisted member and an officer cannot marry.
To be eligible for promotion from E-4 to E-5, you must have completed basic training and any necessary advanced training programs and demonstrated strong leadership skills, commitment to your unit, and consistent performance of your duties.
