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-rikusen-tai: In the narrow sense, a temporal unit consists sailors for ground battles. In the wide sense, a general term means Navy Land Force.
 * Japanese Special Naval Landing Forces or 海軍特別陸戦隊 Kaigun-tokubetsu-rikusen-tai: the Japanese Marines
 * The Base Force or 根拠地隊 Konkyo-chitai and The Special Base Force or 特別根拠地隊 Tokubetsu-konkyo-chitai provided services, primarily security, to naval facilities
 * Defence Units or 防備隊 Bōbi-tai or 防衞班 Bōei-han: detachments of 200 to 400 men.
 * Guard Forces or 警備隊 Keibi-tai: detachments of 200–500 men who provide security to Imperial Japanese Navy facilities
 * Air Defence Units or 防空隊 Bōkū-tai: Antiaircraft artillery units of 200-300 men equipped with 8 Anti-Aircraft guns or 24 AA machine guns.
 * Pioneers or Construction Units or 海軍設営隊 Kaigun-setsuei-tai built naval facilities, including airstrips, on remote islands. Most of personnel were civilian employees and unarmed.
 * The Naval Communications Units or 通信隊 Tsūshin-tai of 600–1,000 men to provide basic naval communications. They also handled encryption and decryption.
 * The Tokkeitai 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 Keishi-chō civil police and Tokkō secret units in security and intelligence services.

Although both the Keibi-tai and Bōbi-tai received amphibious assault and beach defence training, their performance was poor or average when they were used as assault troops.
