Footnotes

[1] Unless otherwise noted, names, positions held, organization titles, and periods of service were taken from the muster rolls of the units concerned, held in the Diary Unit, Files Section, Records Branch, Personnel Department, Headquarters Marine Corps. Units are listed only for those periods, indicated by the dates below parent unit designation for which they are entitled to campaign participation credit. This information is derived from muster rolls and U.S. Bureau of Naval Personnel. Navy and Marine Corps Awards Manual-NAVPERS 15,790 (Rev. 1953) with changes (Washington, 1953-1958). The muster rolls have been the final authority when there is a conflict in dates of unit entitlement within the overall campaign period as cited by the Awards Manual. In the case of Marine air units, many of which participated in the campaigns as flight or advance echelons only, the unit commander who was actually in the combat area is shown where muster rolls reveal this information. In order to conserve space, only units of battalion and squadron size, or larger, and sizeable separate detachments are listed for each operation, although smaller organizations may have participated also.

[2] Operations within the Gilberts include the capture of Tarawa, Makin and Apamama.

[3] No replacement colonel was available for the artillery regiment when Bourke was promoted to brigadier general, therefore he remained in command for the Tarawa operation.

[4] Includes: Kwajalein-Majuro Occupation, 29Jan-8Feb44; Eniwetok Occupation, 17Feb-2Mar44.

[5] Tactical Group I, V Amphibious Corps, consisting of headquarters staff and the 22d Marines (Reinforced), as well as other supporting units, represented the Fleet Reserve during the Kwajalein-Majuro operation and is shown in detail under Eniwetok, 17Feb-2Mar44.

[6] Under each unit listed there will appear a letter designation for each operation in which the unit participated, and dates of involvement. Following are the campaigns and dates of entitlements:

A.	Gilbert Islands		13Nov-8Dec43
B.	Marshall Islands
	1.	Kwajalein-Majuro	29 Jan-8Feb44
	2.	Eniwetok	17Feb-2Mar44
C.	Saipan		11Jun-10Aug44
D.	Tinian		24Jul-1Aug44
E.	Guam		12Jul-15Aug44
