From 23 August to 3 September the Far East Command allotted to the 7th Division the entire infantry replacement stream reaching FEC, and from 23 August through 8 September the entire artillery replacement stream.
By 4 September the division had received 390 officers and 5,400 enlisted replacements. General MacArthur obtained service units for the X Corps in the same way-by diverting them from scheduled assignments for Eighth Army. The Far East Command justified this on the ground that, while Eighth Army needed them badly, X Corps' need was imperative. [25-12]
In response to General MacArthur's instructions to General Walker on 11 and 13 August to send South Koreans to augment the 7th Infantry Division, 8,637 of them arrived in Japan before the division embarked for Inch'ŏn. Their clothing on arrival ranged from business suits to shirts and shorts, or shorts only. The majority wore sandals or cloth shoes. They were civilians-stunned, confused, and exhausted. Only a few could speak English. Approximately 100 of the South Korean recruits were assigned to each rifle company and artillery battery; the buddy system was used for training and control. [25-13]
The quality of the artillery and infantry crew-served weapons troops received from the United States and assigned to the 7th Division during August and early September was high. The superior training provided by the old infantry and artillery noncommissioned officers who arrived from the Fort Benning Infantry and the Fort Sill Artillery Schools brought the 7th Division to a better condition as the invasion date approached than could have been reasonably expected a month earlier. The 7th Division strength on embarkation,[ ??? when???] including the attached South Koreans, was 24,845. [25-14]
