The Secretary of Defense (Marshall) to the Secretary of State

top secret

Dear Mr. Secretary: In the attached memorandum of 17 January 1951 the Joint Chiefs of Staff have submitted their views regarding the request of the Korean Government that the Korean Youth Corps be armed, and regarding the general question of increasing Korean forces to resist Communist aggression. The Joint Chiefs of Staff have concluded that there is not, at present, any desirable, feasible and timely method of appreciably increasing the Korean forces to resist Communist aggression.

Accordingly, I am forwarding this memorandum to you, for your information, with the request that, whenever appropriate, the Department [Page 106] of State inform representatives of the Korean Government that, from the military point of view, the most effective utilization of members of the Korean Youth Corps and other qualified males at present is to replace losses in existing ROK units.

Faithfully yours,

G. C. Marshall

Subject: Proposed Arming of the Korean Youth Corps.

1.
In accordance with your memorandum of 14 December 1950,1 the Joint Chiefs of Staff have considered the request of the Korean Government that the Korean Youth Corps be armed, and the general question of increasing Korean forces to resist Communist aggression.2
2.
Initial study indicated that, although no machine guns, mortars, anti-tank weapons or artillery can be made available for additional Korean forces, there are sufficient small arms and ammunition available in Zone of Interior stocks to increase Korean forces by from 200,000 to 300,000 men, armed with rifles, automatic rifles, carbines and sub-machine guns. Further, it seemed probable that on the order of 75,000 to 100,000 of these men might profitably be utilized to:
a.
Augment the rifle strength of Republic of Korea (ROK) divisions and U.N. forces;
b.
Form special units for guarding lines of communication and for operations against Communist guerrillas; and
c.
Conduct guerrilla operations in Communist-held territory.
3.
However, it is General MacArthur’s opinion that such utilization of additional Koreans would be of questionable value. His comments with respect to the subparagraphs above are substantially as follows:
a.
In the combat areas, withdrawal of U.N. forces, including the current retrograde movement from the Seoul vicinity, has been due in most instances to the inability of ROK units to maintain the integrity of their assigned sectors. This failure has been repeated in situations involving either North Korean or Chinese forces and, whenever determined enemy pressure is encountered, appears to have equal application to ROK divisions closely integrated in U.S. corps zones as well as those operating directly under ROK Army control. In consequence, it now appears that any possibility of checking the enemy may be dependent upon the establishment of a defensive position of such proportions that U.S. divisions can be deployed in depth in mutually supporting locations.
b.
Continued effort has been made since 25 June 1950 to effect the most practicable utilization of Korean personnel. In addition to materially augmenting the ROK Army, members of the Youth Corps and other qualified males have been supplied with significant quantities of small arms for the purpose of strengthening police units and anti-guerrilla security elements. Despite the relatively large number of non-army personnel now under arms, enemy guerrilla units continue to operate effectively in many widely scattered regions of South Korea.
c.
Furthermore, members of the Youth Corps and other qualified males have been supplied with arms for the creation of special organizations to operate in Communist held territory. Such guerrilla forces, however, have accomplished little in Communist rear areas, primarily due to lack of strong-willed leadership.
d.
On the basis of past accomplishments of ROK armed forces, the probable restricted size of the battlefield in which U.N. forces may soon be operating and the high priority of requirements for the National Police Reserve of Japan, the most effective utilization of available Korean manpower in the near future would be to replace losses in existing ROK units. Any long-range requirement for, or desirability of, arming additional ROK personnel appears to be dependent primarily upon determination of the future U.S. military position with respect to both the Korean campaign and the generally critical situation in the Far East.
4.
In view of the above the Joint Chiefs of Staff conclude that there is not at present any desirable, feasible and timely method of appreciably increasing Korean forces to resist Communist aggression.
5.
Accordingly, the Joint Chiefs of Staff recommend that you inform representatives of the Korean Government and the Secretary of State that, from the military point of view, experience indicates that the most effective utilization of members of the Korean Youth Corps and other qualified Korean males is to replace losses in existing ROK units.
For the Joint Chiefs of Staff:
