This publication is Part IV of the overall document, WE WENT TO WAR, a series of historical data reports on the 380th Bombardment Group (Heavy), Fifth Air Force, United States Air Forces. The 380th served in the South West Pacific Area during World War II. They served in the Northern Territory, Australia (under overall Australian command) and periodically in New Guinea from May 1943 — February 1945. Then they served in The Philippines (Mindoro) from March — August 1945 and had moved to Okinawa by war's end.

We are particularly indebted to Ms. Sue Goble of the Force Integration Division, U.S. Total Army Personnel Command, United States Army, Alexandria, Virginia, for her most willing service in providing us annotated copies of the pertinent U.S. Army personnel documents which defined the MOS/SSN procedure during World War II.

Without her outstanding help this whole series of reports would be much less complete than they can be now. We have taken the liberty to add her name to our Compilers List of this Part as a small token of our thanks to her. We hope she approves and accepts our heartfelt thanks.

Any military unit of the size of a World War II Heavy Bombardment Group requires a very large number of different personnel skills among its approximately 8,000 personnel. This is particularly so when the unit must serve in an isolated area far from its sources of supply and assistance from other related military units. Such was the 380th Bomb Group which served in the Northern Territory of Australia, New Guinea, and The Philippines (Mindoro) during World War II.

Fortunately, the United States Army had foreseen the need for such capability and had instituted an elaborate personnel classification and training system to supply such a need. The occupational skills and specialties needed have been recorded as MOS/SSN numbers (Military Occupational Specialties/Service Specialty Numbers) and are described in a series of Army Regulations and Technical Manuals.

We, the compilers of this series of documents, have, to the extent possible, listed the MOS/SSN number and title for each individual on our roster. It is noted that the assignment of MOS numbers as used here seems to bear little relationship to related occupational skills.

The information that made this analysis possible was supplied by Ms. Sue Goble of the Force Integration Division, U.S. Total Army Personnel Command, United States Army, Alexandria, Virginia. She supplied us with copies of the pertinent pages from the following documents:

Army Regulations, AR 615-26, Sections 7 and 17, Civilian and Military Occupational Specialists (Date Unknown), and

Technical Manual, TM12-427, Section IV, Specifications for Military Occupational Specialties, dated 30 June 1945,

and other documents as needed. This document would have been impossible without this help.

The MOS/SSN numbers changed several times during World War II as indicated by the redundancy in Occupational Specialty Names used here and the occasional double use of some numbers. Such numbers were radically revised during the 1960s and since, and current usage is radically different than that of World War II, again highlighting the value of the information supplied by Ms. Goble.

This document is divided into five sections as follows:

Section 1: Alphabetical Officer MOS Listings

Section 2: Numerical Officer MOS Listings

Section 3: Alphabetical Enlisted MOS Listings

Section 4: Numerical Enlisted MOS Listings

Section 5: Division of MOS Designations by Department Assigned

The Departments are:

    1. Administration and Services
    2. Armament
    3. Communications
    4. Engineering — Facilities Engineering and Maintenance
    5. Engineering — Aircraft and Related Maintenance
    6. Intelligence
    7. Medical
    8. Operations
    9. Ordnance
    10. Supply
    11. Transportation

In all cases, both MOS Number and Title are presented. Many specialties are needed in more than one Department. This is indicated when known. We have not attempted to include the specifications of each of the MOS/SSNs presented because of the bulk involved and because the titles themselves are generally quite explanatory.
