Imperial Japanese Navy Land Forces

Imperial Japanese Navy Land Forces of World War II originated with the Special Naval Landing Forces, and eventually consisted of the following:

*The Naval Landing Force or "海軍陸戦隊 Kaigun Rikusentai": In the narrow sense, a temporal unit consists sailors for ground battles. In the wide sense, a general term means Navy Land Force.
*Special Naval Landing Force or "海軍特別陸戦隊 Kaigun Tokubetsu Rikusentai": the Japanese Marines
*The Base Force or "根拠地隊 Konkyotitai"　and The Special Base Force or "特別根拠地隊 Tokubetsu Konkyochitai" provided services, primarily security, to naval facilities
*Defence units or "防備隊 Bobitai" or "Boei-han": detachments of 200 to 400 men.
*Guard forces or "警備隊 Keibitai": detachments of 200–500 men who provide security to Imperial Japanese Navy facilities
*Air Defence units or "防空隊 Bokutai": Antiaircraft artillery units of 200-300 men equipped with 8 Anti-Aircraft guns or 24 AA machine guns.
*Pioneers or " Kaigun Setsueitai" built naval facilities, including airstrips, on remote islands. Most of personnel are civilian employees and unarmed.
*The Naval Communications Units or "通信隊 Tsushintai" of 600–1,000 men to provide basic naval communications and also handled encryption and decryption.
*The "Tokeitai" Navy military police units were part of the naval intelligence armed branch, with military police regular functions in naval installations and occupied territories; they also worked with the Imperial Japanese Army's Kempeitai military police, the Keishicho civil police and Tokko secret units in security and intelligence services. Although both the "keibitai" and "bobitai" received amphibious assault and beach defence training, their performance was poor or average when they were used as assault troops.
