Restoration of the provisions of Silla’s military-related laws

It was generally recognized that the ancient Japanese Gunbangryeong(軍防令) was created solely based on the Tang Yulryeong(律令). However, in the latter half of the 7th century, the relationship between Japan and the Tang was severed, and the information necessary for the interpretation and application of the Tang Yulryeong were transmitted from Silla. Many of the differences between Japanese Yulryeong and the Tang Yulryeong can be said to be the result of influence from the Silla Yulryeong. Therefore, by examining the differences along with Silla cases, it is possible to restore the provisions of Silla. Comparing the corresponding articles of Tang and Japan, which presented the composition of the command, while the former describes the number of administrative officials and the size of the troops divided into two sections, the latter stipulates the number of all commanders and divides the size of the troops into three sections. In particular, Bujanggun(副將軍), which is difficult to find examples of in China, is included in the article, which can be confirmed in the cases of Silla. The Bujanggun of Silla was a position that assisted the general, and it is presumed that it was introduced to Japan as a term officially used in Silla. Japanese Gunbangryeong added a troop size range of 3,000 to 5,000. This means that the minimum number of people who could independently wage war in Japan was 3,000, and it was also an important unit of organization in Silla. The cases of the 3,000 Silla army going on an expedition ac- counts for the largest proportion, and the installation of the Samcheondang(三千幢) in the mid-6th century shows that the Silla army was standardized around this time based on 3,000 people. In particular, the Umlihwasamcheondangjoo(音里火三千幢主) shows that the importance of the 3,000-man unit did not disappear until the later period.
