JAPANESE DELIBERATE FIELD FORTIFICATIONS undated captured on SAIPAN

EDITORS NOTE

This is the most comprehensive set of deliberate field fortification layouts and specifications that has been found to date Some of the diagrams in this set have appeared in previous publications suppleshymented by photographs sketches and comments (In particular _see JICPOA Bulletin 71-44 Japanese Military Installations 15 June 1944 with Supplement of 25 sept 1944 CINCPAC-CINCPOA Special Translashytion 59 Heavy DP Gun Emplacements 100mm Type 98 120mm Type 10 contains supplementary material For detailed information suppleshymenting the section on AA Installations consult CINCPAC-GINCPOA Special Translation 62)

Translations of captured fortification plans issued by area forces have also been published (GILBERTS JICPOA Item 3769 Standard Japanese Field Fortifications mdash Selected MARSHALLS JICPOA Items 8056 Permanent Fortifications and 6365 Information On Obstacles Used To Impede Landing Craft and Amphibious Vehicles mdash 4th Fleet Planning Section also JICPOA Items 7785 Special Fire Points Covered Rifle and Gun Emplacements and 7723 Notes on Beach Obshystacles mdash 1st Amphibious Brigade MARIANAS JICPOA Item 9535F Plans For Construction of Dummy Batteries On GUAM mdash MARIANAS Grp Hq)

In addition ATIS has published similar reports covering the Southwest Pacific Areas and Part I of the Japanese Infantry Field Fortificashytion Manual (Enemy Publication 50 23 Oct 1943)bullbullbull Further informashytion on fortifications may be found in published Defense Plans of OGASAWARA PALAU the MARIANAS etc

To a large degree all have been adaptations to local conditions of plans in this set with emphasis on the use of on-the-spot materials The Japanese in fortifying their more remote territories lacked materials to construct the elaborate installations called for in some of these plans However reconnaissance photographs and the experience of recent operations would seem to indicate that we shall in the homeshyland encounter deliberate fortifications which are up to official specifications Cut-ltand-cover fortifications will be dug deeper than indicated herein andor their walls and ceilings will be thicker andor bursU^g^layers provided Specifications captured on OKINAWA call for wgtft ffj|rffl |J^iEinrf| 3r$ jiy3 0$ jgeterB thick for MG Pillboxes (Casemates ioff P^Jd-mreJSu^bi amp ~$5 ^^^^Jor ftegi-rcental or Mountain GuEJ S M p ^ J amp B M ^ 2 meters Artillery Observation rostsW^i^^sJ^^OTjfcTplaconients for Rif3es and MG 13 meters) Cave-type construction with either open-cut or horizontal shaft will undoubtedly be substituted whenever possible

JAPANESE DELIBERATE FIELD FORTIFICATIONS undated captured on SAIPAN

EDITORS NOTE

This is the most comprehensive set of deliberate field fortification layouts and specifications that has been found to date Some of the diagrams in this set have appeared in previous publications suppleshymented by photographs sketches and comments (In particular _see JICPOA Bulletin 71-44 Japanese Military Installations 15 June 1944 with Supplement of 25 sept 1944 CINCPAC-CINCPOA Special Translashytion 59 Heavy DP Gun Emplacements 100mm Type 98 120mm Type 10 contains supplementary material For detailed information suppleshymenting the section on AA Installations consult CINCPAC-GINCPOA Special Translation 62)

Translations of captured fortification plans issued by area forces have also been published (GILBERTS JICPOA Item 3769 Standard Japanese Field Fortifications mdash Selected MARSHALLS JICPOA Items 8056 Permanent Fortifications and 6365 Information On Obstacles Used To Impede Landing Craft and Amphibious Vehicles mdash 4th Fleet Planning Section also JICPOA Items 7785 Special Fire Points Covered Rifle and Gun Emplacements and 7723 Notes on Beach Obshystacles mdash 1st Amphibious Brigade MARIANAS JICPOA Item 9535F Plans For Construction of Dummy Batteries On GUAM mdash MARIANAS Grp Hq)

In addition ATIS has published similar reports covering the Southwest Pacific Areas and Part I of the Japanese Infantry Field Fortificashytion Manual (Enemy Publication 50 23 Oct 1943)bullbullbull Further informashytion on fortifications may be found in published Defense Plans of OGASAWARA PALAU the MARIANAS etc

To a large degree all have been adaptations to local conditions of plans in this set with emphasis on the use of on-the-spot materials The Japanese in fortifying their more remote territories lacked materials to construct the elaborate installations called for in some of these plans However reconnaissance photographs and the experience of recent operations would seem to indicate that we shall in the homeshyland encounter deliberate fortifications which are up to official specifications Cut-ltand-cover fortifications will be dug deeper than indicated herein andor their walls and ceilings will be thicker andor bursU^g^layers provided Specifications captured on OKINAWA call for wgtft ffj|rffl |J^iEinrf| 3r$ jiy3 0$ jgeterB thick for MG Pillboxes (Casemates ioff P^Jd-mreJSu^bi amp ~$5 ^^^^Jor ftegi-rcental or Mountain GuEJ S M p ^ J amp B M ^ 2 meters Artillery Observation rostsW^i^^sJ^^OTjfcTplaconients for Rif3es and MG 13 meters) Cave-type construction with either open-cut or horizontal shaft will undoubtedly be substituted whenever possible

JAPANESE DELIBERATE FIELD FORTIFICATIONS undated captured on SAIPAN

EDITORS NOTE

This is the most comprehensive set of deliberate field fortification layouts and specifications that has been found to date Some of the diagrams in this set have appeared in previous publications suppleshymented by photographs sketches and comments (In particular _see JICPOA Bulletin 71-44 Japanese Military Installations 15 June 1944 with Supplement of 25 sept 1944 CINCPAC-CINCPOA Special Translashytion 59 Heavy DP Gun Emplacements 100mm Type 98 120mm Type 10 contains supplementary material For detailed information suppleshymenting the section on AA Installations consult CINCPAC-GINCPOA Special Translation 62)

Translations of captured fortification plans issued by area forces have also been published (GILBERTS JICPOA Item 3769 Standard Japanese Field Fortifications mdash Selected MARSHALLS JICPOA Items 8056 Permanent Fortifications and 6365 Information On Obstacles Used To Impede Landing Craft and Amphibious Vehicles mdash 4th Fleet Planning Section also JICPOA Items 7785 Special Fire Points Covered Rifle and Gun Emplacements and 7723 Notes on Beach Obshystacles mdash 1st Amphibious Brigade MARIANAS JICPOA Item 9535F Plans For Construction of Dummy Batteries On GUAM mdash MARIANAS Grp Hq)

In addition ATIS has published similar reports covering the Southwest Pacific Areas and Part I of the Japanese Infantry Field Fortificashytion Manual (Enemy Publication 50 23 Oct 1943)bullbullbull Further informashytion on fortifications may be found in published Defense Plans of OGASAWARA PALAU the MARIANAS etc

To a large degree all have been adaptations to local conditions of plans in this set with emphasis on the use of on-the-spot materials The Japanese in fortifying their more remote territories lacked materials to construct the elaborate installations called for in some of these plans However reconnaissance photographs and the experience of recent operations would seem to indicate that we shall in the homeshyland encounter deliberate fortifications which are up to official specifications Cut-ltand-cover fortifications will be dug deeper than indicated herein andor their walls and ceilings will be thicker andor bursU^g^layers provided Specifications captured on OKINAWA call for wgtft ffj|rffl |J^iEinrf| 3r$ jiy3 0$ jgeterB thick for MG Pillboxes (Casemates ioff P^Jd-mreJSu^bi amp ~$5 ^^^^Jor ftegi-rcental or Mountain GuEJ S M p ^ J amp B M ^ 2 meters Artillery Observation rostsW^i^^sJ^^OTjfcTplaconients for Rif3es and MG 13 meters) Cave-type construction with either open-cut or horizontal shaft will undoubtedly be substituted whenever possible

JAPANESE DELIBERATE FIELD FORTIFICATIONS undated captured on SAIPAN

EDITORS NOTE

This is the most comprehensive set of deliberate field fortification layouts and specifications that has been found to date Some of the diagrams in this set have appeared in previous publications suppleshymented by photographs sketches and comments (In particular _see JICPOA Bulletin 71-44 Japanese Military Installations 15 June 1944 with Supplement of 25 sept 1944 CINCPAC-CINCPOA Special Translashytion 59 Heavy DP Gun Emplacements 100mm Type 98 120mm Type 10 contains supplementary material For detailed information suppleshymenting the section on AA Installations consult CINCPAC-GINCPOA Special Translation 62)

Translations of captured fortification plans issued by area forces have also been published (GILBERTS JICPOA Item 3769 Standard Japanese Field Fortifications mdash Selected MARSHALLS JICPOA Items 8056 Permanent Fortifications and 6365 Information On Obstacles Used To Impede Landing Craft and Amphibious Vehicles mdash 4th Fleet Planning Section also JICPOA Items 7785 Special Fire Points Covered Rifle and Gun Emplacements and 7723 Notes on Beach Obshystacles mdash 1st Amphibious Brigade MARIANAS JICPOA Item 9535F Plans For Construction of Dummy Batteries On GUAM mdash MARIANAS Grp Hq)

In addition ATIS has published similar reports covering the Southwest Pacific Areas and Part I of the Japanese Infantry Field Fortificashytion Manual (Enemy Publication 50 23 Oct 1943)bullbullbull Further informashytion on fortifications may be found in published Defense Plans of OGASAWARA PALAU the MARIANAS etc

To a large degree all have been adaptations to local conditions of plans in this set with emphasis on the use of on-the-spot materials The Japanese in fortifying their more remote territories lacked materials to construct the elaborate installations called for in some of these plans However reconnaissance photographs and the experience of recent operations would seem to indicate that we shall in the homeshyland encounter deliberate fortifications which are up to official specifications Cut-ltand-cover fortifications will be dug deeper than indicated herein andor their walls and ceilings will be thicker andor bursU^g^layers provided Specifications captured on OKINAWA call for wgtft ffj|rffl |J^iEinrf| 3r$ jiy3 0$ jgeterB thick for MG Pillboxes (Casemates ioff P^Jd-mreJSu^bi amp ~$5 ^^^^Jor ftegi-rcental or Mountain GuEJ S M p ^ J amp B M ^ 2 meters Artillery Observation rostsW^i^^sJ^^OTjfcTplaconients for Rif3es and MG 13 meters) Cave-type construction with either open-cut or horizontal shaft will undoubtedly be substituted whenever possible
