A cap badge, also known as head badge or hat badge, is a badge worn on uniform headgear and distinguishes the wearer's nationality and/or organisation. The wearing of cap badges is a convention commonly found among military and police forces, as well as uniformed civilian groups such as the Boy Scouts, civil defence organisations, ambulance services, customs services, fire services etc.

The Special Naval Landing Forces were the marines of the Imperial Japanese Navy (IJN) and were a part of the IJN land forces. They saw extensive service in the Second Sino-Japanese War and in the Pacific theatre of World War II. The SNLF should not be confused with the Naval Landing Forces, which were primarily ad-hoc units of naval personnel formed into naval infantry units whom rarely performed proper amphibious operations and were primarily utilized in a defensive role ashore.
A peaked cap, peaked hat, service cap, barracks cover, or combination cap is a form of headgear worn by the armed forces of many nations, as well as many uniformed civilian organisations such as law enforcement agencies and fire departments. It derives its name from its short visor, or peak, which was historically made of polished leather but increasingly is made of a cheaper synthetic substitute.

The Indonesian National Armed Forces (TNI) uses a simplified ranking system for the three branches of Indonesian Army, Indonesian Navy and Indonesian Air Force. Most of the ranks are similar with differences for the rank titles of the high-ranking officers. Exception exists, however, in the ranks of the service members of the Indonesian Marine Corps. While Indonesian Marine Corps is a branch of the Navy, the rank titles of the Marine Corps are the same as those of the Army, but it still uses the Navy's style insignia.

In the United States Armed Forces, the ranks of warrant officer and chief warrant officer are rated as officers above all non-commissioned officers, candidates, cadets, and midshipmen, but subordinate to the lowest officer grade of O‑1. This application differs from the Commonwealth of Nations and other militaries, where warrant officers are the most senior of the other ranks, equivalent to the U.S. Armed Forces grades of E‑8 and E‑9.

The ranks and rank insignia of the Red Army and Red Navy between 1940 and 1943 were characterised by continuing reforms to the Soviet armed forces in the period immediately before Operation Barbarossa and the war of national survival following it. The Soviet suspicion of rank and rank badges as a bourgeois institution remained, but the increasing experience of Soviet forces, and the massive increase in manpower all played their part, including the creation of a number of new general officer ranks and the reintroduction of permanent enlisted ranks and ratings.
Between 1943 and 1955, the ranks and insignia of the Soviet Armed Forces were characterised by a number of changes, including the reintroduction of rank insignia badges and the adoption of a number of higher ranks.
Ranks and insignia of the Russian Federation's armed forces from 1994 to 2010 were affected by the disintegration of the former Soviet armed forces, and there were other changes in insignia design when the newly established Russian Federation came into existence. The ranks depicted below were replaced with those adopted by decree № 293 of the President of the Russian Federation on 11 March 2010. The transition began with the issue of new military uniforms to the armed services in 2008 in the Moscow area and in 2010 nationwide. The ranks of marshal of the branch and chief marshal were officially abolished as a result of the 1994 regulations.
The extensive system of uniforms of the Russian Armed Forces was inherited from the Soviet Armed Forces and modified across the years.
Pilot training in the Imperial Japanese Navy (IJN) had several programs, which expanded, evolved and changed throughout the years. The aim of these programs was to train aircrew for the Imperial Japanese Navy Air Service (IJNAS). Initially, the pilot training program was open only to officers who graduated from the Imperial Japanese Naval Academy. However, the training was extended to include non-commissioned officers (NCO) in March 1914 and eventually also to enlisted navy personnel in May 1920. Over the years, the number of NCO and enlisted pilots significantly surpassed the number of commissioned officer pilots, and officers would typically only command units and lead formations in combat. As the Pacific War progressed and attrition impacted the units, it was not uncommon for NCOs to lead battle formations due to the lack of officers, and some units even ended up without officers, as in the case of 204th Air Group in summer 1943 after Operation SE. Prior to the Pacific war, the training programs were extremely selective and competitive, and produced only a small number of elite pilots every year. However, during the Pacific War, a rapid increase in the demand for replacement pilots significantly reduced the selectiveness and training time.
