They do not show all details of their subordinate units. Below is a table of summary T/Os and their subordinate T/Os. Please order the T/Os listed in the right hand column for all subordinate unit details. Please also note that some of the subordinate units in the right hand column are themselves summary T/Os (with their own subordinate units). |

Specific Notes
Note 1 | This document is retyped from the original T/O, with all data faithfully reproduced. The original T/O could not be used for photocopying due to its poor condition. |
Note 2 | Includes changes as of 22 July 1944. |
Note 3 | The only equipment data provided by this T/O is the individual weapon assignment (i.e. whether the Marine carried a carbine, pistol, rifle, or automatic rifle). |
Note 4 | This T/O was approved 1 May 45 and revised 17 October 45 |
Note 5 | It would appear that since Okinawa was invaded on 1
April 45 that these Marine units would not have been organized under these
T/Os. However, pages 694-695 of the book Victory and Occupation , by B.
M. Frank and H. I. Shaw, Jr., Volume V of the History of U. S. Marine Corps
Operations in World War II, states: "Although the G-Series [Marine Division] T/O was not published until 4 September 1945, after the Pacific War had ended, the tables of some division units had been published earlier. For example, the T/O for an infantry regiment is dated 1 May 1945, but this is misleading because many of the changes inherent in the G-Series had been made before this time. A case in point is the fact that the Marine infantry regiments which landed on Okinawa just a month before the T/O publication date were organized in accordance with these tables. ... Further indicating that the 1st and 6th Marine Divisions were organized on Okinawa in accordance with the G-Series tables is the fact that the 75mm self-propelled gun platoon had been replaced by the 105mm self-propelled howitzer platoon in the regimental weapons company prior to the landing." |
Note 6 | This T/O contains a few hand markings but is legible. |
